BACKGROUND Microbial biofuel synthesis attracting increasing attention. Great advances have been made in producing fatty alcohols from fatty acyl-CoAs and fatty acids in Escherichia coli. However, the low titers and limited knowledge regarding the basic characteristics of fatty alcohols, such as location and toxicity, have hampered large-scale industrialization. Further research is still needed...
Glycols and ethoxy– propoxy–alcohols are fundamental chemicals in industry, with annual productions of millions tons, still manufactured many cases corrosive unrecoverable catalysts such as KOH, amines BF3•OEt2. Here we show that commercially available, inexpensive, non–toxic, solid recyclable nanotitania catalyzes the hydration alkoxylation epoxides, water primary secondary alcohols but not ph...

Clean synthesis of biolubricant range esters using novel liquid lipase enzyme in solvent free medium
In view of the rising global problems of environment pollution and degradation, the present process provides a 'green solution' to the synthesis of higher esters of lubricant range, more specifically in the range C12-C36, using different combinations of acids and alcohols, in a single step reaction. The esters produced are biodegradable in nature and have a plethora of uses, such as in additive...
Plant cell cultures effectively convert terpenoid and aromatic alcohols into glycosides. A quantitative comparison showed a culture of peppermint (Mentha piperita) to be the most active among four species examined. The synthesis of glycosides was affected by the concentration of substrate, incubation period, cell age and aggregation, and by light. Conversion rates of exogenous alcohols were gre...
