Oxidative stress is responsible for the advent of seizure hence, antioxidants are used for the treatment neurodegenerative ailments such as epilepsy. Profoundly, Butea monosperma possess several medicinal properties and the preliminary phytochemical screening revealed the presence of steroids, alkaloids, triterpenoids, polyphenols, flavonoids, tannins, and glycosides in the leaves. Thus, the present study aimed to evaluate the bioactive potentials in the isolated crude flavonoid fraction (FF) from the leaves. FF was isolated by successive methanol extract method and was evaluated for antioxidant and anticonvulsant activities in vitro and in vivo. For in vivo study, 25 healthy Wistar Albino rats were employed in five groups (Gp): Gp 1: control, Gp 2: standard group receiving phenytoin sodium and Gp 3-5: test groups receiving oral doses of FF i.e., 50, 100 and 200 mg/kg, respectively. In vitrodata showed concentration-dependent antioxidant activity (88.86±0.006%), reducing power activity (0.694±0.002%) and nitric oxide scavenging activity (87.98±0.013%). In vivo, a significant depression in the phases and percentage incidence of convulsions was observed in the maximal electroshock model in a dose-dependent manner. The pentylene tetrazole-induced seizure model also depicted a significant (p≤0.001) decrease in the latency of convulsions and an increase in the percentage protection against the convulsions in a dose-dependent manner. Our findings suggest antioxidant and anticonvulsant potential of FF obtained from Butea monosperma leaves.
氧化应激是癫痫发作的原因,因此抗氧化剂被用于治疗神经退行性疾病,如癫痫。不仅如此,单精子茶还具有多种药用特性,初步的植物化学筛选发现其叶片中含有类固醇、生物碱、三萜、多酚、黄酮类化合物、单宁和苷类化合物。因此,本研究旨在评价从叶中分离的黄酮粗提取物(FF)的生物活性潜力。采用甲醇连续提取法分离FF,体外和体内评价FF的抗氧化和抗惊厥活性。体内实验选用健康Wistar Albino大鼠25只,分为5组(Gp): Gp 1为对照组,Gp 2为苯妥英钠标准组,Gp 3-5为试验组,分别口服FF 50、100和200 mg/kg。体外实验结果显示其抗氧化活性(88.86±0.006%)、还原力活性(0.694±0.002%)和一氧化氮清除活性(87.98±0.013%)呈浓度依赖性。在体内,在最大电休克模型中观察到惊厥的阶段和百分比发生率明显降低,并呈剂量依赖性。戊二烯四唑诱导的癫痫模型也以剂量依赖的方式描述了惊厥潜伏期的显著(p≤0.001)减少和对惊厥的保护百分比的增加。我们的研究结果表明,从单精子Butea叶中提取的FF具有抗氧化和抗惊厥的潜力。

4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-11-01 DOI: 10.56042/ijeb.v61i11.3650
Basella alba fruit extract (BAFE) has been used in rural eastern India by the traditional practitioners to treat anemia during pregnancy. In the present study, hematopoietic and hepatoprotective activity of BAFE was established in animal model. Animal ethical permission was obtained before experiments. Male Swiss albino rats were divided into: gr.1- sham control, gr.2- disease control (anemia or hepatotoxicity), gr.3- standard drug treated, gr.4- BAFE treated (low dose) and gr.5- BAFE treated (high dose). Anemia was induced in animals through blood loss at regular intervals and hematological, cytokine, antioxidant parameters and RBC morphology were done. Hepatotoxicity was induced in animals by CCl4 (1 mL/kg/p.o.) and serum biochemistry, cytokine, antioxidant parameters and histology were done. There was a significant improvement of hematology (Hb, TC of RBC, TC of WBC, hematocrit, serum iron, TIBC), cytokine (IL 1β), antioxidant (SOD, catalase, LPO, GSH) and RBC morphology in BAFE treated animals when compared to group 2 animals. Significant improvement in biochemical (AST, ALT, γGT, ACP, ALP, total bilirubin), cytokine (IL 1β, IL 4, IL 12, IL 17, cathepsin K, TNF α), antioxidant (SOD, catalase, LPO, GSH) and liver histology were observed in BAFE treated animals when compared to group 2 animals. The present study confirmed the hematopoietic and hepatoprotective activity of BAFE in animal model and warrants further studies.

Anti-inflammatory effect of ethanolic extract of Ocimum basilicum L. in the healing process of incisional wounds in mice 罗勒乙醇提取物在小鼠切口伤口愈合过程中的抗炎作用
4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-11-01 DOI: 10.56042/ijeb.v61i11.1908
Maintaining the structural and functional integrity of the skin is critical to ensuring body homeostasis. After damage, a series of cellular and molecular events occurs in this structure in order to repair the injured tissue. Imbalances in one or more repair steps are commonly related to difficulties in proceeding with healing. In this sense, the search for treatments that improve the repair has encompassed research with several plants, given the possibility of effects on one or more stages, the reduction of costs and possible side effects. Ocimum basilicum, used globally from cooking to practices in folk medicine, has in its phytoconstitution substances with different actions such as anti-inflammatory, antioxidant, antimicrobial. Therefore, the present study aimed to evaluate the anti-inflammatory effect of intraperitoneal treatment with ethanolic extract of Ocimum basilicum (EEOB) on wound healing in mice. Incisional wounds were induced in mice, they were divided according to treatment period and group, n=6, and received EEOB intraperitoneally (i.p.) at 150 mg/kg daily or saline solution for 5 or 7 days. At the end of this period, the animals were euthanized and the lesions underwent histopathological processing and analysis. In animals treated with EEOB injection, there was a decrease in the number of leukocytes at 5 days and mast cells at 7 days post-injury compared to the control. The observed anti-inflammatory action can be associated with the presence of several phenolic compounds and their individual or synergistic effects on the evaluated process. Keywords: Healing; medicinal plants; inflammation.
维持皮肤的结构和功能的完整性是确保身体稳态的关键。损伤后,在该结构中发生一系列细胞和分子事件,以修复受损组织。一个或多个修复步骤中的不平衡通常与继续愈合的困难有关。从这个意义上说,寻找改善修复的治疗方法包括对几种植物的研究,考虑到可能对一个或多个阶段产生影响,降低成本和可能的副作用。罗勒在全球范围内从烹饪到民间医学实践中都有使用,其植物构成物质具有不同的作用,如抗炎、抗氧化、抗菌。因此,本研究旨在评价罗勒乙醇提取物(EEOB)腹腔注射对小鼠伤口愈合的抗炎作用。取小鼠切口创面,按治疗周期和组分,n=6只,每日150 mg/kg或生理盐水腹腔注射EEOB,连续5、7 d。在这段时间结束时,对动物实施安乐死,并对病变进行组织病理学处理和分析。在注射EEOB的动物中,与对照组相比,在损伤后5天白细胞数量和7天肥大细胞数量减少。观察到的抗炎作用可能与几种酚类化合物的存在及其对所评估过程的单独或协同作用有关。关键词:愈合;药用植物;炎症。

4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-11-01 DOI: 10.56042/ijeb.v61i11.1916
Protective effect of Diospyros Kaki leaves extract against oxidative damage and inflammation in the testicular ischemia-reperfusion model were investigated in the study. 32 male rats were randomly and equally divided into 4 groups. While saline (SF) was given to the control and ischemia/reperfusion (I/R) groups for 5 days, Diospyros Kaki (DK) and I/R+DK were given 200 mg/kg of DK leaf extract. Afterwards, left orchiectomy was performed in control and DK, and testicular torsion was performed in I/R and I/R+DK for 2 hours. All rats were sacrificed 24 hours after procedures and samples were collected. Compared to the control, I/R had high MDA levels, low GSH and GSH-Px levels; compared to the I/R, MDA levels of the I/R+DK were lower, and the GSH and GSH-Px levels were higher. In I/R, the presence of congestion and hemorrhage were determined and the deterioration in seminiferous tubule structure and spermatogenesis were less in the I/R+DK. TNF-α, COX-2, BCL-2, and BAX genes expressions significantly lower in the I/R+DK. TNF-α and COX-2 proteins were higher in I/R and I/R+DK, while NRF2 was higher in I/R+DK. These results show DK leaves extract has crucial protective effect against oxidative damage and inflammation in the I/R model of rats.

Abelmoschus esculentus (L.) Moench seed extract alleviates acute acetaminophen induced liver damage in rats 绿毛鼠(L.)芒硝子提取物减轻对乙酰氨基酚所致大鼠急性肝损伤
4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-11-01 DOI: 10.56042/ijeb.v61i11.1326
Acetaminophen (APAP) is one of the most regularly utilized medicines in children. When administered at the recommended doses, it is a safe medication. However, oxidative stress and inflammation caused by exposure to toxic doses lead to centrilobular hepatic necrosis. N-acetylcysteine (NAC) is utilized in the therapy, however it has potentially adverse effects. On the other hand, it is known that the seed of Abelmoschus esculentus (AE), a herbal product, possesses antioxidant and anti-inflammatory qualities. The aim of this study is to investigate whether AE may be used as an alternative to standart NAC therapy without fear of adverse effects in the treatment of acute APAP-induced liver injury. Forty male Wistar rats were placed into five groups: Control, AE, APAP, APAP+AE, and APAP+AE+NAC groups. Antioxidants such as native thiol and total thiol can be raised in the APAP group by taking just AE (p=0.043 and p=0.028, respectively). Anti-inflammatory indicators such as IL-10 can be increased in this group, while markers such as ALT, which is a sign of hepatotoxicity, can be decreased (p=0.005 and p<0.001, respectively). Histologically, AE has been shown to improve worsened congestion (p=0.003), cytoplasmic vacuolization (p=0.01), sinusoidal dilatation (p=0.001), Kupffer cell proliferation (p<0.001), and inflammation (p<0.001). These results suggest that AE seed may be a potential therapeutic agent for APAP-induced hepatotoxicity. The antioxidant and anti-inflammatory properties of AE seed contribute to this advantage.
对乙酰氨基酚(APAP)是儿童最常用的药物之一。按推荐剂量服用时,它是一种安全的药物。然而,暴露于有毒剂量引起的氧化应激和炎症可导致小叶中心肝坏死。n -乙酰半胱氨酸(NAC)用于治疗,但它有潜在的副作用。另一方面,众所周知,草籽(AE)是一种草药产品,具有抗氧化和抗炎的特性。本研究的目的是探讨在急性apap诱导的肝损伤治疗中,AE是否可以作为标准NAC治疗的替代方案,而无需担心不良反应。将40只雄性Wistar大鼠分为5组:对照组、AE组、APAP组、APAP+AE组和APAP+AE+NAC组。仅服用AE可提高APAP组抗氧化剂的天然硫醇和总硫醇含量(p=0.043和p=0.028)。IL-10等抗炎指标升高,ALT等肝毒性指标降低(p=0.005, p= 0.001)。组织学上,AE已被证明可以改善恶化的充血(p=0.003)、细胞质空泡化(p=0.01)、窦状窦扩张(p=0.001)、库普弗细胞增殖(p=0.001)和炎症(p=0.001)。这些结果表明,AE种子可能是apap诱导的肝毒性的潜在治疗剂。AE种子的抗氧化和抗炎特性有助于这一优势。

Apoptotic and antiproliferative effects of Urtica dioica L. extract on K562 chronic myeloid leukemia cell line 杜鹃花提取物对慢性髓系白血病K562细胞的凋亡和抗增殖作用
4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-11-01 DOI: 10.56042/ijeb.v61i11.1574
Urtica dioica (stinging nettle) is an herb commonly in use as a medical supplement for its anticarcinogenic, antiinflammatory, analgesic, antifungal . In this study, phytochemical composition extract was analyzed and its apoptotic and antiproliferative effects were investigated in K562 cell line, a model cell line for chronic myeloid leukemia (CML). K562 cells exposed to different concentrations of Urtica dioica extract (0, 25, 50, 75 and 100 mg/ml) were tested for cell proliferation and appropriate methods and different phases of the cell cycle were analyzed using flow cytometry. Phenolic content of the plant was analyzed by LC–MS/MS. We showed that Urtica dioica ethanol extract has four phenolic compounds: caffeic acid, chlorogenic acid (major compound), malic acid and rutin. Urtica dioica significantly repressed proliferation of K562 cells compared to control mononuclear cells (PBMCs) isolated from the peripheral blood of healthy donors. Increase in Bax/Bcl-2 and PARP cleavage ratio, decrease in mitochondrial membrane potential indicated that the extract inhibited cell proliferation through an apoptosis-mediated process. Furthermore, cell cycle arrest at G0/G1 phase increased in a concentration dependent manner. Our results explicitly demonstrate that ethanol extract of to decrease in cell viability and proliferation, initiate apoptosis and induces G0/G1 cell cycle accumulation in this cell line. This study is the first to show antiproliferative and apoptotic effects of Urtica dioica on leukemia cell line in vitro.                                  
荨麻(荨麻)是一种草药,因其抗癌、抗炎、镇痛、抗真菌而被广泛用作医疗补充剂。本研究分析了植物化学成分提取物对慢性髓性白血病(CML)模型细胞株K562细胞的凋亡和抗增殖作用。采用流式细胞术检测不同浓度荨麻提取物(0、25、50、75、100 mg/ml)对K562细胞增殖的影响,分析不同浓度荨麻提取物对K562细胞增殖的影响。采用LC-MS /MS法对其酚类物质含量进行分析。结果表明,杜鹃花乙醇提取物中含有咖啡酸、绿原酸(主要化合物)、苹果酸和芦丁四种酚类化合物。与从健康供者外周血中分离的对照单核细胞(PBMCs)相比,荨麻疹明显抑制K562细胞的增殖。增加Bax/Bcl-2和PARP切割比,降低线粒体膜电位,表明提取物通过凋亡介导的过程抑制细胞增殖。此外,细胞周期阻滞在G0/G1期以浓度依赖的方式增加。我们的研究结果明确表明,乙醇提取物可以降低该细胞系的细胞活力和增殖,启动细胞凋亡,诱导G0/G1细胞周期积累。本研究首次在体外实验中证实了荨麻对白血病细胞的抗增殖和凋亡作用。,,,,,,,,,,,,,,,,今天早上

K562 cells exposed to different concentrations of Urtica dioica extract (0, 25, 50, 75 and 100 mg/ml) were tested for cell proliferation and appropriate methods and different phases of the cell cycle were analyzed using flow cytometry.

The immune system is the main responsible candidate to induce pro-inflammatory conditions in the hospitalized SARS-CoV-2 infected patients. The roles played by humoral immunity-related factors in the pro-inflammatory conditions of the patients are yet to be clarified. It has been revealed that a proliferation-inducing ligand (APRIL), interferon (IFN)-γ-inducible protein 10 (IP-10), and microRNA-16-5p (miR-16-5p) play key roles in the induction of inflammation. Thus, this project was aimed to explore the expression levels of the molecules in the SARS-CoV-2 infected patients with severe symptoms. In addition, miR-194 can inhibit immune responses against viral infection. Another aim of this study was to evaluate expression of the molecule in the patients to explore the effects of the molecule during coronavirus disease 2019 (COVID-19). In this project, 60 severe SARS-CoV-2 infected patients who were in the peak of the disease and 60 healthy controls were enrolled to evaluate APRIL, IP-10, miR16-5p, and miR-194 expression levels. IP-10 expressions were evaluated using enzyme linked immunoassay (ELISA), while APRIL, miR-16-5p, and miR-194 were evaluated using Real-Time PCR technique. The results showed that APRIL, miR-16-5p, and miR-194 expression and serum levels of IP-10 significantly increased in the hospitalized SARS-CoV-2 infected patients in comparison to healthy controls. There was a positive correlation between miR-16-5p and miR-194 levels in the patients. Due to the fact that miR-16-5p significantly participates in the induction of inflammation, it, APRIL, and IP-10 may be the main parts of the excess inflammation in the hospitalized SARS-CoV-2 infected patients with severe symptoms. Up-regulation of miR-194 may be natural negative feedback to the pro-inflammatory conditions and may be associated with establishment of SARS-CoV-2 infection.
在住院的SARS-CoV-2感染患者中,免疫系统是诱导促炎的主要负责候选者。体液免疫相关因子在患者的促炎条件中所起的作用尚不清楚。研究发现,增殖诱导配体(四月份)、干扰素(IFN)-γ-诱导蛋白10 (IP-10)和microRNA-16-5p (miR-16-5p)在炎症诱导中起关键作用。因此,本项目旨在探讨这些分子在SARS-CoV-2感染重症患者中的表达水平。此外,miR-194可以抑制对病毒感染的免疫应答。本研究的另一个目的是评估该分子在患者中的表达,以探索该分子在2019冠状病毒病(COVID-19)期间的作用。本项目选取60例处于疾病高峰期的SARS-CoV-2严重感染患者和60例健康对照者,评估其APRIL、IP-10、miR16-5p和miR-194的表达水平。采用酶联免疫分析法(ELISA)检测IP-10的表达,采用Real-Time PCR技术检测APRIL、miR-16-5p和miR-194的表达。结果显示,与健康对照组相比,住院SARS-CoV-2感染患者的APRIL、miR-16-5p、miR-194表达和血清IP-10水平均显著升高。患者miR-16-5p与miR-194水平呈正相关。由于miR-16-5p显著参与炎症的诱导,因此它、APRIL和IP-10可能是住院重症SARS-CoV-2感染患者过度炎症的主要部分。miR-194的上调可能是对促炎条件的自然负反馈,并可能与SARS-CoV-2感染的建立有关。

The curry leaf extract is known to have anticancer property against breast cancer. Identification of the specific compound therein the curry leaf and its validation is essential for successful discovery of drugs. In that content, here, we extracted oleoresin from the mature curry leaves was subjected to antioxidant fractionation using column chromatography. Fraction obtained using 60:40 hexane and ethyl acetate solvent system, showing the maximum inhibition of DPPH, was subfractionated and those with the highest antioxidant property was analyzed in LC-MS/MS. Spectrum of molecules identified, along with FDA approved drugs, were docked with target proteins for breast cancer. In vitro screening of candidate phytocompounds doxylamine, histidinol and pheniramine, in their commercially available form, through Trypan blue exclusion assay against murine cancer cell lines EAC and DLA had shown that they have no cytotoxicity. Pheniramine maleate salt (PMS), doxylamine succinate salt (DSS) and L-histidinol dihydrochloride (LHD) have shown dose-dependent inhibition of proliferation of MCF-7 cells, with 280 μg/mL PMS at 72 h of incubation giving the maximum of 98.46%. Acute toxicity studies in Swiss albino mice (100 mg PMS/kg body wt.) have confirmed that the drug has no toxicity. Mouse mammary pad tumour model has shown that PMS significantly reduces the WBC count in the tumour induced mice. Liver function tests, histopathological analyses of liver, mammary pad and kidney tissues and expression analysis of oncogenes ER-α1, Bcl-2, c-Myc and Pin1 have confirmed the drug candidature of PMS.
众所周知,咖喱叶提取物对乳腺癌具有抗癌作用。咖哩叶中特定化合物的鉴定和验证对药物的成功开发至关重要。在该含量中,我们从成熟的咖喱叶中提取油树脂,用柱层析法进行抗氧化分馏。以60:40的正己烷和乙酸乙酯为溶剂体系,对DPPH抑制效果最好的馏分进行了次分馏,并对抗氧化性能最好的馏分进行了LC-MS/MS分析。已确定的分子光谱,以及FDA批准的药物,与乳腺癌的靶蛋白对接。对市售的候选植物化合物多西胺、组氨酸和苯那敏进行了体外筛选,通过台苯蓝排除法对小鼠癌细胞系EAC和DLA进行了体外筛选,结果表明它们没有细胞毒性。马来酸苯那敏盐(PMS)、琥珀酸多西胺盐(DSS)和l -组氨酸二盐酸盐(LHD)对MCF-7细胞的增殖抑制呈剂量依赖性,培养72 h时,PMS对MCF-7细胞的抑制作用为280 μg/mL,最大抑制率为98.46%。对瑞士白化病小鼠的急性毒性研究(100 mg PMS/kg体重)证实该药物没有毒性。小鼠乳腺垫肿瘤模型显示,经前ms可显著降低肿瘤诱导小鼠的白细胞计数。肝功能检查、肝脏、乳腺垫和肾脏组织病理学分析以及癌基因ER-α1、Bcl-2、c-Myc和Pin1的表达分析证实了PMS的候选药物。

Intensified biodegradation of Congo red dye by mixed culture in a sequential bioreactor: Kinetics and phytotoxicity studies 顺序生物反应器中混合培养强化刚果红染料的生物降解:动力学和植物毒性研究
4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-09-29 DOI: 10.56042/ijeb.v61i10.1686
Although textile industries lead the economic sector in several countries, the pollution that they cause, particularly to water bodies, is a serious environmental concern. Dyes and their metabolites are harmful to human and aquatic life due to their toxic, mutagenic, and carcinogenic potential. In this study, we have made an effort to treat the complex Congo red (CR) dye-containing wastewater in an anaerobic-aerobic sequential bioreactor. The impact of CR dye concentration (20-100 mg/L) on the performance of sequential bioreactor was examined. The CR dye removal efficiencies (REs) of 97, 88.1, 75.9, 68.7, and 42.56% were obtained at 20, 40, 60, 80 and 100 mg/L of CR dye, respectively. Similarly, the overall Chemical oxygen demand (COD) RE of 90% was also obtained. It was found that the CR dye and COD REs were high at low concentrations of CR dye. The obtained experimental data was fitted with growth and substrate inhibition models. A phytotoxic study indicated that the Chickpea (Cicer arietinum L.) grown in treated wastewater showed better germination (93%) than untreated wastewater (66%).
虽然纺织工业在若干国家的经济部门中占主导地位,但它们造成的污染,特别是对水体的污染,是一个严重的环境问题。染料及其代谢产物具有毒性、诱变性和致癌性,对人类和水生生物有害。在本研究中,我们尝试在厌氧-好氧序列生物反应器中处理含刚果红(CR)染料的复合废水。考察了CR染料浓度(20 ~ 100 mg/L)对序式生物反应器性能的影响。在CR染料浓度为20、40、60、80和100 mg/L时,CR染料去除率分别为97、88.1、75.9、68.7和42.56%。同样,总化学需氧量(COD) RE也达到90%。结果表明,在低浓度CR染料条件下,CR染料和COD REs较高。得到的实验数据符合生长和底物抑制模型。一项植物毒性研究表明,鹰嘴豆(Cicer arietinum L.)在处理后的废水中萌发率(93%)高于未处理的废水(66%)。

A plate assay to screen manganese-tolerant Aspergillus niger strains 筛选耐锰黑曲霉菌株的平板试验
4区 生物学 Q Biochemistry, Genetics and Molecular Biology Pub Date : 2023-09-29 DOI: 10.56042/ijeb.v61i10.830
Two different physiological effects of Mn[II] interactions with Aspergillus niger are known. Excess Mn[II] levels are toxic and restrict fungal radial growth on plates and second, an Mn[II] limited fungal growth is the key to successful citric acid fermentation. While studying Mn[II] toxicity we noted that the Mn[II]-supplemented minimal medium (MM) agar plates were translucent. Also, clearing zones around the fungal colonies owing to organic acid release were observed. Simultaneous scoring of these two parameters was exploited to screen for Mn[II] tolerant/ insensitive A. niger strains with improved acid production. Clear halos were best viewed on MM plates supplemented with ≥ 5.0 mM of Mn[II]. Accordingly, an acid unit (AU; the ratio of diameter of the clear zone to that of colony diameter) was defined. Colonies that produced larger zones of clearing (and higher AUs) were picked up and sub-cultured. A Mn[II] tolerant/ insensitive spontaneous mutant of A. niger was isolated by this screen and characterized. It produced significantly higher amounts of citric acid and the yield was not adversely affected by the added Mn[II]. While separate screens for metal tolerance and citric acid production were reported earlier, the method presented here is simple and directly combines the two features for strain selection/screening.
锰[II]与黑曲霉相互作用的两种不同的生理效应是已知的。过量的Mn[II]水平是有毒的,限制真菌在平板上的径向生长;其次,Mn[II]限制真菌的生长是柠檬酸发酵成功的关键。在研究Mn[II]毒性时,我们注意到Mn[II]补充的最小培养基(MM)琼脂板是半透明的。此外,由于有机酸释放,真菌菌落周围出现了清理区。利用这两个参数的同时评分来筛选Mn[II]耐受性/不敏感的黑曲霉菌株。在添加≥5.0 MM Mn[II]的MM板上观察到的光晕最清晰。因此,一个酸单位(AU;定义了透明区直径与菌落直径之比。产生更大的空地(和更高的AUs)的菌落被捡起并进行继代培养。通过该筛选分离到一株耐/不敏感的黑曲霉Mn[II]自发突变体,并对其进行了鉴定。它产生的柠檬酸量显著增加,并且添加的Mn[II]对产率没有不利影响。虽然之前报道过金属耐受性和柠檬酸产量的单独筛选,但本文提出的方法简单,直接结合了菌株选择/筛选的两个特征。
