Production of wax esters during aerobic growth of marine bacteria on isoprenoid compounds

Article Abstract:

The production of isoprenoid wax esters during the aerobic growth of four marine bacteria species when grown on 6,10,14-trimethylpentadecan-2-one and free phytol has been studied. The bacterial strains are Acinetobacter sp. strain PHY9, Pseudomonas nautica IP85/617, Marinobacter sp. strain CAB and Marinobacter hydrocarbonoclasticus. The esters form from the condensation of some acidic and alcoholic metabolites during biodegradation when 6,10,14-trimethylpentadecan-2-one is used. Phytol serves as the alcohol moiety of the esters produced during growth on this isoprenoid alcohol.

Production of a polyunsaturated isoprenoid wax ester during aerobic metabolism of squalene by Marinobacter squalenivorans sp. nov.

Article Abstract:

Research discusses the formation of a polyunsaturated isoprenoid wax ester via aerobic metabolism of squalene by a bacterial strain, 2Asq64, a new representative species of Marinobacter. The new species is named as M. squalenivorans sp. nov based on its genetic and physiological differences from a close species in the genus.

Comparison of methods for quantification of cytochrome cd(sub 1)-denitrifying bacteria in environmental marine samples

Article Abstract:

Two molecular techniques can detect 10 to 1,000 times more cytochrome cd(sub 1) denitrifying bacteria in sediment or water samples than traditional cultivation methods. The methods are most-probably-number PCR and competitive PCR, both using the cd3F-cd4R PCR primer set.
