As an alternative to chemical surfactants, the biosurfactants obtained from plants are renewable, biocompatible, biodegradable, less toxic and less expensive. In the present report, the aqueous extract prepared from the pericarps of soapnuts fruits is employed, which are known to exhibit a myriad of biological properties. The extract was characterized using Fourier transform infrared spectroscopy (FTIR) and zeta analyzer for identifying the functional groups and surface charge, respectively. The extract showed abundance of saponins, triterpenoids, flavonoids and negative charge of –8.9 mV. The free radical scavenging and antibacterial activities of the extract were evaluated with DPPH scavenging and well diffusion assays. The DPPH scavenging (%) increased with an increase in extract concentration and showed a significant radical scavenging potential of 85.3% at a concentration of 250 μg/mL. The extract didn’t show antibacterial action on Gram–negative bacteria at the selected concentrations. But, it demonstrated significant inhibitory action on Gram–positive bacteria; Bacillus subtilis and Micrococcus luteus with inhibition zones of 4.0 mm and 12.5 mm at 43.75 mg of crude saponins, respectively. Thus, the green extract used in the present study finds its application as a natural, antibacterial and antioxidant biosurfactant in cosmetic and food industries, as a substitute to chemical surfactants.
作为化学表面活性剂的替代品,从植物中提取的生物表面活性剂具有可再生、生物相容性好、可生物降解、毒性小、价格低廉等特点。在本报告中,采用了从子果皮制备的水提取物,已知其具有无数的生物学特性。利用傅里叶红外光谱(FTIR)和zeta分析仪分别对提取物的官能团和表面电荷进行了表征。提取液中皂苷、三萜、黄酮类化合物含量丰富,负电荷为-8.9 mV。通过DPPH清除和孔扩散试验,评价了提取物的自由基清除和抗菌活性。DPPH清除率(%)随提取物浓度的增加而增加,在浓度为250 μg/mL时,自由基清除率达到85.3%。在所选浓度下,提取物对革兰氏阴性菌无抑菌作用。但对革兰氏阳性菌有明显的抑制作用;43.75 mg粗皂苷对枯草芽孢杆菌和黄体微球菌的抑制区分别为4.0 mm和12.5 mm。因此,本研究中使用的绿色提取物在化妆品和食品工业中作为一种天然的、抗菌的和抗氧化的生物表面活性剂,作为化学表面活性剂的替代品。

Traditional medicines or herbal medicinal compounds are being increasingly considered as useful complementary and alternative treatments for cancer. A large number of in vitro and in vivo studies have reported the beneficial effects of herbal medicines alone and in combination with conventional therapeutics. We developed a polyherbal formulation Swastharakshak® (SR033), exhibiting anti-tumorigenic property. Although, majorly 5-Fluorouracil (5FU) resulted in necrosis of HeLa cells, however in combination with SR033, the majority of cells underwent apoptosis with an increase of 30%, SR033 alone was considered as an experimental control. Moreover, 5FU and PTX resistance were reversed by SR033 with 2.5×103and 0.17×103 fold, respectively, in resistant HeLa-R cells. We observed a 2 fold decrease in free radicals when treated with SR033 as compared to untreated controls; however, 1.2 fold decrease was observed in SR033 + 5FU groups in comparison to 5FU alone.These results demonstrated that SR033 acts synergistically with 5FU, along with chemo-protective and 5FU resistance reversal property. Hence, SR033 is a potential herbal formulation that could be used effectively with 5FU as a combination therapy for cancer.
传统药物或草药化合物越来越多地被认为是癌症的有用补充和替代治疗方法。大量体外和体内研究报告了草药单独使用和与传统疗法联合使用的有益效果。我们开发了一种多羟基制剂Swastharakshak®(SR033),具有抗肿瘤特性。尽管5-氟尿嘧啶(5FU)主要导致HeLa细胞坏死,但与SR033联合使用时,大多数细胞发生凋亡,凋亡率增加30%,单独使用SR033被视为实验对照。此外,SR033在抗性HeLa-R细胞中分别以2.5×103和0.17×103倍逆转5FU和PTX抗性。与未处理的对照组相比,我们观察到用SR033处理时自由基减少了2倍;SR033+5FU组与单独5FU组相比下降了1.2倍。这些结果表明,SR033与5FU协同作用,具有化学保护和5FU耐药性逆转特性。因此,SR033是一种潜在的草药制剂,可以与5FU一起有效地用作癌症的联合治疗。

Dihydrofolate reductase (DHFR) is an enzyme that reduces dihydrofolate to tetrahydrofolate for the denovo synthesis of purines. DHFR is a well-established and classic drug target used in cancer therapy. Several drugs like Methotrexate (MTX), Trimethoprim, Pemetrexed, Pyrimethamine, etc. are known inhibitors of DHFR and presently used to treat cancer patients. Staphylococcus is a major human pathogen and the causative agent of numerous hospital and community-acquired infections. In the present investigation, DHFR of Staphylococcus aureus (PDB Id: 2W9G) was subjected to molecular docking to evaluate whether the anti-cancer drugs, MTX and Pemetrexed strongly bind to the former. The results of molecular docking indicated that MTX and Pemetrexed strongly interact with Staphylococcal DHFR with the binding energy of -8.3kcal/mol and -9.0kcal/mol respectively. To validate the in silicostudies, the antimicrobial property of MTX and pemetrexed was evaluated in clinical strains of S. arlettae and S.sciuriin vitro and the results indicated that MTX but not pemetrexed possessed antimicrobial activity. But the similar antimicrobial effect of the abovementioned drugs was not found in gram-negative bacteria Pseudomonas aeruginosa (ATCC 27853), and E. coli (ATCC 25922). The Minimal Inhibitory Concentration (MIC) of MTX was found to be higher than 2mg/ml for both strains. Even though the MIC values of MTX are high, we propose that structural modification of MTX or its combination with conventional antibiotics may lead to the discovery of the new potential antimicrobial drug.
二氢叶酸还原酶(DHFR)是一种将二氢叶酸还原为四氢叶酸以直接合成嘌呤的酶。DHFR是癌症治疗中公认的经典药物靶点。一些药物如甲氨蝶呤(MTX)、甲氨蝶啶、培美曲塞、嘧啶等是已知的DHFR抑制剂,目前用于治疗癌症患者。葡萄球菌是一种主要的人类病原体,也是许多医院和社区获得性感染的病原体。在本研究中,对金黄色葡萄球菌(PDB Id:2W9G)的DHFR进行分子对接,以评估抗癌药物MTX和培美曲塞是否与前者强结合。分子对接结果表明,MTX和培美曲塞与葡萄球菌DHFR的结合能分别为-8.3kcal/mol和-9.0kcal/mol。为了验证计算机研究的有效性,对MTX和培美曲塞在临床菌株S.arlettae和S.sciurie中的体外抗菌性能进行了评估,结果表明MTX而不是培美曲赛具有抗菌活性。但在革兰氏阴性菌铜绿假单胞菌(ATCC 27853)和大肠杆菌(ATCC 25922)中没有发现上述药物的类似抗菌作用。MTX的最小抑菌浓度(MIC)均高于2mg/ml。尽管MTX的MIC值很高,但我们认为MTX的结构修饰或与传统抗生素的组合可能会导致新的潜在抗菌药物的发现。

Inulinase is an industrially applicable enzyme which is used widely in the production of ultra high fructose syrups and fructo-oligosaccharides. Production of inulinase enzyme in a cost effective manner is the major challenge faced. In the present research study, Trichoderma asperellum RSBR08 which has the capability to produce high exo-inulinase enzyme is produced by using the solid state fermentation. Process parameters for production of exo-inulinase by using solid state fermentation were optimized. Results showed high exo-inulinase production in garlic as substrate (199.2±6.3 U/gds), 45% moisture percentage (228.4±3.4), 26 o C temperature (219.1±5.8) and 5.0 pH (213.6±4.5). Effect of different metals viz. Mg 2+ ,Zn 2+ , K + ,Ca 2+ , Na + ,Mn 2+ and Hg 2+ were studied on the production of exo-inulinase enzyme in which Ca 2+ induced the enzyme production (196.3±5.6) whereas Hg 2+ has inhibited the inulinase production (37.0±3.3). Based on the above results, the solid substrate fermentation parameters optimized can be used industrially.

In the present study, an attempt was made to isolate an efficient Polyhydroxybutyrate producing bacterium from soil. A total of 38 different types of bacteria were isolated, out of which 15 were found to be PHB positive, based on the viable colony staining method of screening using Nile red Dye. The isolate (6N) showed maximum PHB production of 0.17 g/L, and PHB produced was confirmedusing NMR.The most potent isolate (6N-NRC) was identified using 16S rRNA, and phylogenetic analysis clearly demonstrated that the strain 6N-NRC is a member of the genus Bacillus and is identified as Bacillus aryabhattai. The culture medium and growth parameters were optimized using one factor at a time, multifactorial experimental design (PlackettBurman and Box-Behnken) and utilization of Beet molasses as cheap and economic carbon source for maximum PHB production was done. Beet molasses (30 g/L) as the carbon and ammonium chloride (0.75 g/L) as the nitrogen source were found to be the best nutritional sources for maximum PHB production. Incubation time period 36h, pH of the medium at 8.0 and temperature of 300C were found to be optimum conditions for obtaining maximum PHB yield of 3.799 g/L.
本研究试图从土壤中分离出一种高效产聚羟基丁酸的细菌。采用尼罗红染色法筛选活菌落,共分离到38种不同类型的细菌,其中PHB阳性15种。该分离物(6N) PHB产率最高,为0.17 g/L,经核磁共振证实其产PHB。利用16S rRNA鉴定了最有效的分离株(6N-NRC),系统发育分析表明菌株6N-NRC为芽孢杆菌属,鉴定为芽孢杆菌aryabhattai。采用单因素优化培养基和生长参数,采用多因素试验设计(PlackettBurman和Box-Behnken),并利用甜菜糖蜜作为廉价经济的碳源,最大限度地生产PHB。以甜菜糖蜜(30 g/L)为碳源,以氯化铵(0.75 g/L)为氮源,可最大限度地提高PHB的产量。培养时间36h,培养基pH为8.0,温度为300C, PHB产率最高可达3.799 g/L。

Saffron adulteration dates back to antiquity a fraudulent act continued to modern day. In recent years the wide use of saffron in medicine and food has been associated with wider use of counterfeit to saffron, nevertheless this has been associated with development of methods to detect such adulteration. The advancement of molecular biology methods has been one of key area used for detection of adulterants. The concept by its own is diverse and different approaches for better detection of adulterant has been developed to support detection of fraudulent activities in particular in food and agriculture industry. To develop primers for detection of saffron adulteration with safflower we designed primer pairs based on universal reference sequence for chloroplast trnl(UUA) Intron that are different in length and size for saffron and sawfflower. The approach was to save tedious work using otherwise RAPD /SCAR (sequenced characterized amplified region)markers to have accurate reproducible results with least interference and higher level of polymorphism of particular and specific conserved region in plants.
藏红花掺假可以追溯到古代,一种欺诈行为一直延续到现代。近年来,藏红花在医药和食品中的广泛使用与藏红花的假冒使用有关,然而,这与检测此类掺假的方法的发展有关。分子生物学方法的发展已成为检测掺杂物的关键领域之一。这一概念本身是多种多样的,已经制定了不同的方法来更好地检测掺杂物,以支持检测欺诈活动,特别是在食品和农业行业。为了开发用于检测红花与红花掺假的引物,我们基于叶绿体trnl(UUA)内含子的通用参考序列设计了引物对,这些引物对在长度和大小上与红花和红花不同。该方法是为了节省使用其他RAPD/SCAR(测序特征扩增区)标记的繁琐工作,以在植物中具有最小干扰和更高水平的特定和特异保守区多态性的情况下获得准确的可重复结果。
