The potential biodegradation of crude oil was assessed based on the development of a fermentative process with a strain of Pseudomonas aeruginosa which produced 15.4 g/L rhamnolipids when cultured in a basal mineral medium using glycerol as a sole carbon source. However, neither cell growth nor rhamnolipid production was observed in the comparative culture system using crude oil as the sole car...

The acetalization of six different types of glycerol including pure, wet, and crude-like grade compounds of compositions simulating those of crude glycerols produced by the biodiesel manufacture, was carried out with two model ketones such as acetone and 2-butanone. The reaction was investigated under continuous-flow (CF) conditions through a comparative analysis of an already known acetalizati...

NADH oxidases (NOXs) play an important role in maintaining balance of NAD+/NADH by catalyzing cofactors regeneration. The expression of nox gene from Lactobacillus brevis in Escherichia coli BL21 (BL21 (DE3)) was studied. Two strategies, the high AT-content in the region adjacent to the initiation codon and codon usage of the whole gene sequence consistent with the host, obtained the NOX activi...

Herein, an optimized method for 100 g scale synthesis of glycerol oligomers using a microwave multimode source and the low priced K2CO3 as catalyst is reported. This method allows the complete conversion of glycerol to its oligomers in only 30 min, yielding molecular weights up to 1000 g mol−1. Furthermore, a simple iterative purification process, involving the precipitation of the crude produc...

The present study was designed to evaluate the composition and acceptability of biscuits prepared by partially replacing hydrogenated vegetable shortening with peanut butter to reduce the fats and enhance the nutritional value. For this objective five different treatments of biscuits were prepared from peanut (Arachis hypogaea) butter and hydrogenated vegetable shortening (Banaspati) i.e. T1(0:...

Crude glycerol, a biodiesel industry byproduct, and corn steep liquor (CSL) derived from starch industry, were used as carbon nitrogen sources, respectively, for lipid production, using the heterotrophic microalga C. cohnii grown in bench bioreactor, batch culture. The maximum biomass concentration, content productivity attained 5.34 g/L, 24.6% (w/w Dry Cell Weight-DCW) 0.016 g L−1 h−1, respect...
