Abstract:
... We have conducted a thorough study on extracellular biosynthesis of silver nanoparticles (AgNPs) by a halotolerant bacterium Bacillus endophyticus SCU-L, which was identified by 16S rRNA gene sequencing analysis. This strain was selected during an ongoing research programme aimed at finding a novel biological method for green nanosynthetic routes using the extremophiles in unexplored hypersaline h ...

Abstract:
... The efficacy of different concentrations of NaOH (0.25%, 0.50%, 0.75%, and 1.00%) for the pretreatment of rice straw in solid and powder state in enzymatic saccharification and fermentation for the production of bioethanol was evaluated. A greater amount of biomass was recovered through solid-state pretreatment (3.74 g) from 5 g of rice straw. The highest increase in the volume of rice straw powde ...

Abstract:
... The possibility of obtaining recombinant fibrillogenic fusion proteins such as transthyretin (TTR) and β2-microglobulin (β2M) with a superfolder green fluorescent protein (sfGFP) was studied. According to the literature data, sfGFP is resistant to denaturating influences, does not aggregate during renaturation, possesses improved kinetic characteristics of folding, and folds well when fused to dif ...

Abstract:
... Biosynthesis of metal nanoparticles is an area of interest among researchers because of its eco-friendly approach. Current study focuses at biosynthesis of silver nanoparticles (AgNPs) and optimization of physico-chemical conditions to obtain mono-dispersed and stable AgNPs having antimicrobial activity. Initially Bacillus mojavensis BTCB15 produced silver nanoparticles (AgNPs) of 105 nm. Silver n ...

Abstract:
... Imbalance of free radicals over antioxidants in human body may result in oxidative damage to biomolecules (lipids, proteins, DNA) that causes severe chronic diseases. The aim of this proposed research was to examine the hypoglycemic and oxidative stress potential of fava bean (Vicia faba L.) seed extract. Acetone extract showed a significant effect on glucose uptake rate (77.28 ± 2.42%) in yeast c ...

Abstract:
... Protease inhibitors are known to resist damage to host organisms against external threats, hence form a part of their defense system. This property of protease inhibitors was studied on protecting oxidatively stressed Saccharomyces cerevisiae yeast cells. The protease inhibitor was extracted from Agaricus bisporus, an edible mushroom. The inhibitor showed the presence of antioxidant activity as th ...

Abstract:
... Folate-targeted drug delivery has become an alternative therapy for the treatment of various cancers. Folate receptors are known to be responsible for cellular accumulation of folate and folate analogs with high binding affinity. The anthracycline antibiotic doxorubicin has a broad spectrum of antineoplastic action and a correspondingly widespread degree of clinical use. In this work, we aimed to ...
