validation of novel therapeutic activities of withaferin a using molecular docking and dynamics studies.

Withaferin A is a bioactive molecule of We access its efficacy against various target proteins associated with Cancer, Type-II Diabetes and hypercholesterolemia using molecular docking. Although it's efficacy against some of these targets have been reported earlier, we validate each mechanism in order to report the most appropriate mechanism of action. We explain the anti-cancer activity of Withaferin A by inhibition of Mortalin (mtHsp70) and Nrf2 protein with binding energies -8.

An updated review on advancement in fermentative production strategies for biobutanol using Clostridium spp.

A significant concern of our fuel-dependent era is the unceasing exhaustion of petroleum fuel supplies. In parallel to this, environmental issues such as the greenhouse effect, change in global climate, and increasing global temperature must be addressed on a priority basis. Biobutanol, which has fuel characteristics comparable to gasoline, has attracted global attention as a viable green fuel alternative among the many biofuel alternatives.

Economic and sustainable management of wastes from rice industry: combating the potential threats.

Rice is one of the imperative staple foods, particularly in the developing countries. The exponential boom in human population has resulted in the continuous expansion in the rice industry in order to meet the food demands. The various stages of paddy processing release huge quantity of solid wastes, mainly rice husk, rice husk ash and liquid wastes in the form of rice industry wastewater.

Metabolic engineering of Clostridium acetobutylicum for the enhanced production of isopropanol-butanol-ethanol fuel mixture.

Butanol is considered as a superior biofuel, which is conventionally produced by clostridial acetone-butanol-ethanol (ABE) fermentation. Among ABE, only butanol and ethanol can be used as fuel alternatives. Coproduction of acetone thus causes lower yield of fuel alcohols.

Acetone-butanol-ethanol production with high productivity using Clostridium acetobutylicum BKM19.

Conventional acetone-butanol-ethanol (ABE) fermentation is severely limited by low solvent titer and productivities. Thus, this study aims at developing an improved Clostridium acetobutylicum strain possessing enhanced ABE production capability followed by process optimization for high ABE productivity. Random mutagenesis of C.

Butanol production from renewable biomass by clostridia.

Global energy crisis and limited supply of petroleum fuels have rekindled the worldwide focus towards development of a sustainable technology for alternative fuel production. Utilization of abundant renewable biomass offers an excellent opportunity for the development of an economical biofuel production process at a scale sufficiently large to have an impact on sustainability and security objectives. Additionally, several environmental benefits have also been linked with the utilization of renewable biomass.

Continuous butanol production with reduced byproducts formation from glycerol by a hyper producing mutant of Clostridium pasteurianum.

Butanol, a four-carbon primary alcohol (C(4)H(10)O), is an important industrial chemical and has a good potential to be used as a superior biofuel. Bio-based production of butanol from renewable feedstock is a promising and sustainable alternative to substitute petroleum-based fuels. Here, we report the development of a process for butanol production from glycerol, which is abundantly available as a byproduct of biodiesel production.

Butanol production from renewable biomass: rediscovery of metabolic pathways and metabolic engineering.

Biofuel from renewable biomass is one of the answers to help solve the problems associated with limited fossil resources and climate change. Butanol has superior liquid-fuel characteristics, with similar properties to gasoline, and thus, has the potential to be used as a substitute for gasoline. Clostridia are recognized as a good butanol producers and are employed in the industrial-scale production of solvents.

Rapid screening and isolation of a fungus for sitosterol to androstenedione biotransformation.

Androstenedione (AD) is a steroid intermediate used in the pharmaceutical industry for the production of several important anabolic drugs. An important route for producing AD is by the microbial transformation of sterols. Microbes capable of efficiently transforming sterols to AD are few and newer strains need to be isolated.

Enhanced biotransformation of sitosterol to androstenedione by Mycobacterium sp. using cell wall permeabilizing antibiotics.

Mycobacterial cell wall is rigid and offers a high resistance to the transport of sitosterol into cytosol. The effect of ethambutol, penicillin, polymixin and bacitracin on biotransformation of sitosterol to androstenedione by modification of cell wall permeability was examined. Drug sensitivity assay results established that bacitracin increased the permeability of the cell wall to hydrophobic compounds.

Nutrient broth/PEG200/TritonX114/Tween80/Chloroform microemulsion as a reservoir of solubilized sitosterol for biotransformation to androstenedione.

Microemulsions (ME) can act as a reservoir of solubilized hydrophobic substrates. The biotransformation of hydrophobic sitosterol to androstenedione (AD) with MEs prepared from nutrient broth and PEG 200 (1:1) as aqueous phase, 40 g/l sitosterol dissolved in chloroform as organic phase, Triton X114 and Tween 80 (1:1) as surfactant phase, was investigated. The phase behavior of this system was studied for ten different ratios(w/w), 10:0, 9:1, 8:2, 7:3, 6:4, 5:5, 4:6, 3:7, 2:8, 1:9 and 0:10 of the organic phase and surfactant at 30 degrees C.

Androstenedione production by biotransformation of phytosterols.

Androstenedione is a key intermediate of microbial steroid metabolism. It belongs to the 17-keto steroid family and is used as starting material for the preparation of different steroids. Androstenedione can be produced by microbial side chain cleavage of phytosterol, which is an alternative to multi-step chemical synthesis.
