As an alternative to the conventional but expensive gold micro carriers regularly employed in micro-projectile bombardment method, this study had utilized, novel, promising but cheaper clay particles-MMT (montmorillonite) as micro-carriers for gene transfer. Gene expression with novel micro carriers was reported through the universally employed GUS expression system at both transient and stable expression levels in comparison to the gold and tungsten. Results suggest that GUS expression levels are higher with MMT than tungsten carriers but lower to gold carriers. It is interesting to note that the GUS expression zones are larger (>1 mm) with MMT carriers in comparison to tungsten (0.6 mm) and gold (0.4 mm). Molecular assays on the transformed cells suggest proper gene delivery by MMT carriers. The results suggest that novel micro carriers can be a viable alternative to gold for gene transfer with high promise in minimizing the costs without compromising the transformation efficiency.
作为传统的、昂贵的金微载体在微弹轰击法中的替代方案,本研究采用了一种新型的、有前途的、价格低廉的粘土颗粒——蒙脱土作为基因转移的微载体。与金和钨相比,通过普遍使用的GUS表达系统,报道了新型微载体基因在瞬时和稳定表达水平上的表达。结果表明,在MMT中GUS的表达量高于钨载体,而低于金载体。有趣的是,与钨(0.6 mm)和金(0.4 mm)载体相比,MMT载体的GUS表达区更大(>1 mm)。对转化细胞的分子分析表明,MMT载体可以适当地传递基因。结果表明,新型微载体可以作为一种可行的替代金的基因转移方法,在不影响转化效率的情况下,将成本降到最低。

In order to demonstrate the transmission of resistance genes between clinical and community Pseudomonas, 61 strains of Pseudomonas including 47 (77.04%) community Pseudomonas and 14 (22.96%) clinical Pseudomonas were tested with antibiotics by the method of diffusion of the antibiotic discs in solid medium on Mueller Hinton medium. Thirty four strains of DNA comprising 20 (58.82%) community strains and 14 (41.18%) clinical strains exhibiting colistin resistance were extracted; then, the mcr-1 resistance gene was detected by PCR. The antibiotic sensitivity test showed that tobramycin and ciprofloxacin were more active in community and clinical Pseudomonas. The difference was significant with one p<0.05 for five antibiotics between community and clinical Pseudomonas. PCRs of the mcr-1 gene are positive for 8 (40%) community Pseudomonas strains and 5 (35.71%) clinical Pseudomonas strains. The amplified mcr-1 gene fragments were different in size in clinical Pseudomonas.

Isoprene is an industrially important five carbon compound primarily used for production of high quality synthetic rubber. Two major pathways are involved in isoprene synthesis. The mevalonate pathway is present in eukaryotes, archaebacteria and cytosol of higher plants whereas the non-mevalonate pathway exists in many eubacteria and plastids in algae/plants. There have been continuous efforts to study and understand the phenomenon of biological production of isoprene for more than half a century. Although, the current feasibility and cost advantage of chemical processes leading to production of isoprene seems to be far from being dominated by a suitable biological substitute, the fear of extinction of non-renewable resources (raw material for chemical processes) in the near future prompts for a colossal expectation from the synthetic biology community. Technological advances in the field of metabolic engineering have made it possible to vigorously modify and swap genes among different organisms and push the limits for microorganisms to over-produce isoprene to an enormous extent. This review touches upon the limitations faced while improving isoprene titres and the meticulous strategies used to overcome them. It analyzes recent approaches that have resulted in significant improvement of biologically produced isoprene, summarizes the lessons learned from them, and compiles an exhaustive list of potential gene targets that could facilitate prospective research in this widespread arena.
异戊二烯是工业上重要的五碳化合物,主要用于生产高质量的合成橡胶。异戊二烯的合成有两个主要途径。甲羟戊酸途径存在于真核生物、古细菌和高等植物的细胞质中,而非甲羟戊酸途径存在于许多真细菌和藻类/植物的质体中。半个多世纪以来,人们一直在不断努力研究和了解异戊二烯的生物生产现象。虽然目前化学工艺生产异戊二烯的可行性和成本优势似乎远未被合适的生物替代品所主导,但对不可再生资源(化学工艺原料)在不久的将来灭绝的恐惧促使合成生物学界产生了巨大的期望。代谢工程领域的技术进步使得在不同生物之间大力修饰和交换基因成为可能,并在很大程度上推动了微生物过量生产异戊二烯的极限。本文综述了提高异戊二烯滴度所面临的限制以及克服这些限制所采用的细致策略。它分析了最近在生物生产异戊二烯方面取得重大进展的方法,总结了从中吸取的经验教训,并编制了一份详尽的潜在基因目标清单,可以促进这一广泛领域的前瞻性研究。

In this research, we have tried to maximize the potential of Fe3O4 magnetic nanoparticles coated by SiO2 and immobilized with imidazoline hetropolymer (MNPS-IHSP) to stabilize and release the drug molecule called ampicillin (amp). In this purpose, nanoparticles of 50 nm in size were investigated under a tool such as; FT-IR, SEM, EDX detection and its structure in-vitro conditions. MNPS-IHSP nanoparticles is a specific and suitable nanocomposite that it have a mission as well as stabilizing the amp in the presence of silica coating (electrostatic bonding), that it called MNPS-IHSPA, and the results indicate a stabilization with a higher percentage of 85. It was beneficial to the silica coating. This measurement was performed by a UV-V is spectrophotometer analysis. Ultimately, in-vitro conditions, these magnetic nanoparticles that were migrating with ampicillin was tested on growing bacteria and resulted in the bacterial killing, indicating the antibacterial properties of magnetic nanoparticles. Ultimately, the project tells us that it can also be useful for destroying pathogenic bacteria living cells in vivo conditions.
在这项研究中,我们试图最大限度地发挥Fe3O4磁性纳米颗粒的潜力,这些纳米颗粒被SiO2包裹,并被咪唑啉异聚物(MNPS-IHSP)固定,以稳定和释放药物分子氨苄西林(amp)。为此,在以下工具下研究了50纳米尺寸的纳米颗粒:FT-IR, SEM, EDX检测及其体外结构条件。MNPS-IHSP纳米粒子是一种特殊的、合适的纳米复合材料,它具有在二氧化硅涂层(静电键合)存在的情况下稳定放大器的任务,它被称为MNPS-IHSPA,结果表明稳定率高达85%。它有利于二氧化硅涂层的形成。该测量由紫外-紫外分光光度计分析完成。最后,在体外条件下,这些随氨苄西林迁移的磁性纳米颗粒在生长的细菌上进行了测试,并导致细菌死亡,这表明磁性纳米颗粒的抗菌特性。最终,该项目告诉我们,它也可以用于在体内条件下摧毁致病菌活细胞。

Petroleum is a complex mixture of hydrocarbons. No single species of microorganisms is able to degrade all components of the petroleum. Mutually beneficial interaction of microorganisms in the form of a consortium is required during the process of oil degradation. One form of mutually beneficial interaction between fungi and bacteria is biofilm formed by bacteria on fungal surface. The formation of bacterial biofilm on fungal surface was reported to increase the synergistic action of the two microorganisms in destroying certain complex compounds. This work was aimed to assess the capacity of hydrocarbon degrading-bacterial biofilm on the surface of hydrocarbon degrading-fungal surface to degrade hydrocarbons derived from drill cuttings. The hydrocarbon degrading-soil bacteria and fungi were isolated from different area in Yogyakarta, Indonesia after enrichment. The ability of bacteria to form biofilm on the surface of fungal hyphae was examined under light microscope with 1000x magnification after the addition of lactophenol. The effect of microbial amendment in the form of biofilm, in comparison with the planktonic culture, on degradation of hydrocarbons derived from drill cuttings were assessed by measuring the extractable petroleum hydrocarbon. The results showed that co-culture between fungi and bacteria which one among them or both of them have low ability to degrade hydrocarbon may significantly improve their ability and the ability of the co-culture to degrade hydrocarbon has no relationship with the ability of the bacteria to form biofilm on the surface of the fungal hyphae.
石油是碳氢化合物的复杂混合物。没有一种微生物能够降解石油的所有成分。在石油降解过程中,微生物以联合体的形式相互作用是必要的。真菌与细菌相互作用的一种形式是细菌在真菌表面形成的生物膜。据报道,真菌表面细菌生物膜的形成增加了两种微生物在破坏某些复杂化合物时的协同作用。本研究旨在评价烃类降解真菌表面的烃类降解细菌生物膜对钻屑烃类的降解能力。在印度尼西亚日惹市不同地区分离到烃类降解土壤细菌和真菌。加入乳酚后,在1000倍放大镜下观察细菌在真菌菌丝表面形成生物膜的能力。通过测量可提取的石油烃,对比浮游培养和生物膜形式的微生物改良对钻屑烃类降解的影响。结果表明,真菌和细菌对烃类的降解能力较差时,其中一种或两种细菌共同培养可显著提高其降解烃类的能力,其降解能力与细菌在真菌菌丝表面形成生物膜的能力无关。

This study aims to test different extracts (water, 70% ethanolic-water and acetal) of Capsicum sp. on the growth of Alternaria sp., Penicillium sp., Fusarium sp. and Aspergillus flavus. The nature of the antifungal activity, the antifungal parameters (MIC, MFC, IC50) and the percentage of survival of the strains were determined with the dilution method. On Alternaria sp., Penicillium sp. and Fusarium sp. strains, values of MFC/MIC ratios of water and 70% ethanol extracts of Capsicum annuum antillais were equal to two. Concerning Capsicum frutescens (soudanais, attie, doux and oiseau) varieties, these values varied from 1 to 2 on the fungal strains. These ratios for most of the strains were lower than 4. These extracts exerted a fungistatic action on chosen strains. The curves obtained had a declining appearance with more or less steep slopes depending on the extracts. These curved were used to obtain the inhibitory concentrations for 50% survival (IC50) of the moulds. The highest activity was achieved at the lowest IC50 values which varied from 0.2 mg/mL to 0.3 mg/mL. Therefore, Capsicum extracts proved to be active on in vitro growth of the fungal strains studied in a dose-dependent manner.
本研究旨在考察辣椒不同提取物(水、70%乙醇水和缩醛)对赤霉、青霉、镰刀菌和黄曲霉生长的影响。用稀释法测定菌株的抑菌活性、抑菌参数(MIC、MFC、IC50)和存活率。辣椒水提取物和70%乙醇提取物对赤霉、青霉和镰刀菌的MFC/MIC比值均为2。对于甜椒(soudanais, attie, doux和oiseau)品种,真菌菌株的这些值在1到2之间变化。大多数菌株的上述比值均小于4。这些提取物对选定的菌株有抑菌作用。所得到的曲线有一个下降的外观,或多或少陡坡取决于提取物。这些曲线用于获得霉菌50%存活率的抑制浓度(IC50)。IC50最小值(0.2 ~ 0.3 mg/mL)时活性最高。因此,辣椒提取物对真菌菌株的体外生长具有一定的剂量依赖性。

Trichoderma has been used as a biocontrol agent against soil borne diseases that cause economic losses for crops. The objectives of the present investigation were (i) to isolate and characterize Trichoderma spp. from Menoufia Governorate and (ii) to evaluate the isolated Trichoderma spp. as potential biocontrol agents against some soil borne diseases. Soil samples were collected from nine districts and 25 isolates were obtained. Methods of identification of macroscopic and microscopic features, and the sequences of ITS and TEF1-α yielded three species; T. harzianum, T. longibrachiatum and T. asperellum. Phylogenetic tree of the identified 22 strains confirmed that the two strains T. longibrachiatum and T. asperellum came together in the same branch while the rest of the strains which were T. harzianum were on the other side of the tree. All 25 Trichoderma strains and isolates exhibited inhibition to the mycelial growth of four pathogenens. They were antagonized by competition mechanism against 000v m Sclerotium spp., by antibiosis against Fusarium oxysporum and partially against Sclerotium spp. and by mycoparasitism against Rhizoctonia solani. Also, they elucidated differences in total chitinolytic activity measured by two different methods and exochitonolytic activity. Finally, no correlation was found between total chitinolytic activities and total protein contents.
木霉已被作为一种生物防治剂用于防治土壤传播疾病,这些疾病给作物造成经济损失。本研究的目的是:(1)从Menoufia省分离木霉并鉴定其特征;(2)评价分离的木霉作为防治某些土壤传播疾病的潜在生物防治剂。在9个地区采集土壤样品,分离得到25株菌株。采用宏观和微观特征鉴定方法,对ITS和TEF1-α序列进行鉴定,得到3种;哈氏霉,长臂霉和曲霉。对鉴定的22株病原菌进行系统发育树分析,结果表明长臂曲霉与曲霉在同一枝上,其余为哈氏曲霉的病原菌在树的另一侧。25株木霉菌株和分离株对4种病原菌的菌丝生长均有抑制作用。对000v m菌核菌具有拮抗作用,对尖孢镰刀菌和部分菌核菌具有拮抗作用,对茄枯丝核菌具有支寄生虫拮抗作用。此外,他们还阐明了两种不同方法测定的总壳质水解活性和外壳质水解活性的差异。最后,总几丁质溶解活性与总蛋白质含量之间没有相关性。

They were antagonized by competition mechanism against 000v m Sclerotium spp., by antibiosis against Fusarium oxysporum and partially against Sclerotium spp. and by mycoparasitism against Rhizoctonia solani. Also, they elucidated differences in total chitinolytic activity measured by two different methods and exochitonolytic activity. Finally, no correlation was found between total chitinolytic activities and total protein contents.","PeriodicalId":16453,"journal":{"name":"Journal of Microbial & Biochemical Technology","volume":"56 1","pages":"9-23"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91312233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: The present study is designed to evaluate the antitumor activity of sulphur containing compounds in Nano formulations against Ehrlisch Ascites Carcinoma (EAC) in female albino mice. Methods: Preparation of sulfur nanoparticles (S-NPs) was done throughout. Firstly, the evaluation of their composition and purity by fourier transform infrared spectrometer (FT-IR) analysis. Secondly, the shape and size of S-NPs were investigated by scanning electron microscopy (SEM) techniques in all S-NPs samples which were prepared with Tetramethylammoniumbromide (TMAB) surfactant, Then, Energy-dispersive X-ray spectroscopy (EDS) for the evaluation of their composition and purity, after that the X-Ray diffraction patterns were measured for prepared S-NPs with TMAB surfactant, and the determination of S-NPs antitumor activity against (breast carcinoma cell line (MCF7), liver carcinoma cell line (HEPG2), colon carcinoma cell line (HCT116), prostatic carcinoma cell line (PC3). Finally, determination biochemical assay of S-NPs by using female mice bearing EAC and of the assessment of liver functions and evaluation of kidney functions and determination of some heart functions in serum and hematology markers. Results: This study revealed that S-NPs showed high strong activities in concentration (5 mg/kg) as it improvement of liver functions production compared to the positive control group, also showed the effect of S-NPs of the kidney functions, heart functions and hematology parameters in all studied groups and a significant increase in activities compared with positive control group. Conclusion: S-NPs play an important role in improving liver functions, kidney functions and the heart functions of resulted in significantly increase activity against tumour and plays an important role in improving oxidative stress resulted in high antiproliferation activity against (MCF-7, HepG2, HCT116 and PC3) cell lines, and significantly increase with S-NPs reduced most of the hematological parameters towards the best compared to the positive control group.
目的:研究含硫化合物纳米制剂对雌性白化小鼠埃利希腹水癌(EAC)的抗肿瘤作用。方法:全程制备硫纳米颗粒(S-NPs)。首先,用傅里叶变换红外光谱仪(FT-IR)分析评价了它们的组成和纯度。其次,采用扫描电镜(SEM)技术研究了四甲基溴化铵(TMAB)表面活性剂制备的S-NPs样品的形状和大小,然后用能谱分析(EDS)对其组成和纯度进行了评价,然后用TMAB表面活性剂测定了制备的S-NPs的x射线衍射图,并测定了S-NPs对乳腺癌细胞株(MCF7)的抗肿瘤活性。肝癌细胞系(HEPG2)、结肠癌细胞系(HCT116)、前列腺癌细胞系(PC3)。最后,采用灌胃EAC雌性小鼠进行S-NPs的生化测定,并对血清和血液学指标进行肝功能、肾功能评估和部分心功能测定。结果:与阳性对照组相比,S-NPs的浓度(5 mg/kg)在改善肝功能产生方面表现出较高的活性,对所有研究组的肾功能、心功能和血液学参数也有影响,与阳性对照组相比,活性显著增加。结论:S-NPs具有改善肝功能、肾功能和心功能的重要作用,可显著提高抗肿瘤活性,改善氧化应激,对(MCF-7、HepG2、HCT116和PC3)细胞系具有较高的抗增殖活性,与阳性对照组相比,S-NPs可显著升高,并使大部分血液学指标降低至最佳水平。
