Face to the increasing demand for energy, the declining availability of fossil fuels and the periodical tensions in the geopolitical context of oil-producing countries have raised serious concerns in the governments worldwide as well as in the public opini ...
An entomopathogenic, Gram-negative bacterium isolated from a female specimen of the fruit fly Drosophila melanogaster was taxonomically characterised. Strain L48(T) was strictly aerobic, non-fermentative, oxidase and catalase positive, rod-shaped, and moti ...
The work develops a strategy for the production of ethanol from lignocellulosic biomass. In this strategy, the cellulose and hemicellulose fractions are simultaneously converted to sugars using a γ-valerolactone (GVL) solvent containing a dilute acid catal ...
An increasing number of industrial bioprocesses capitalize on living cells by using them as cell factories that convert sugars into chemicals. These processes range from the production of bulk chemicals in yeasts and bacteria to the synthesis of therapeuti ...
Ethanol is produced in large scale from sugarcane in Brazil by fermentation of sugars and distillation. This is currently considered as an efficient biofuel technology, leading to significant reduction on greenhouse gases emissions. However, some improveme ...
In order to identify targets for metabolic engineering interventions or understand the physiology of the cell, the first and foremost prerequisite is the knowledge or a hypothesis about the intracellular network state(s). However, even with the advanced me ...
According to the World Health Organization worldwide obesity has more than doubled since 1980. The World health statistics 2012 report shows that one in six adults is obese, one in ten diabetic and one in three has a raised blood pressure. Overweight and o ...
A novel crude glycerol assisted surfactant pretreatment was evaluated for bioethanol production from chili post-harvest residue. Among the various surfactants screened crude glycerol assisted polyethylene glycol (PEG) pretreatment was found to be more effe ...
Milk processing may induce changes in dairy product composition and influence digestibility and nutrient bioavailability. Differences in protein degradation and peptide generation were studied for beta-lactoglobulin and alpha(S1)-casein from commercially a ...
Build-up of fermentation products and hydrochloric acid at a contaminated site undergoing enhanced reductive dechlorination can result in groundwater acidification. Sub-optimal pH conditions can inhibit microbial activity and lead to reduced dechlorination ...
