T. Kaneshiro et al., OLEYL OLEATE AND HOMOLOGOUS WAX ESTERS SYNTHESIZED COORDINATELY FROM OLEIC-ACID BY ACINETOBACTER AND CORYNEFORM STRAINS, Current microbiology, 32(6), 1996, pp. 336-342
Newly isolated Acinetobacter (NRRL B-14920, B-14921, B-14923) and cory
neform (NRRL B-14922) strains accumulated oleyl oleate and homologous
liquid wax esters (C-30:2-C-36:2) in culture broths, Diunsaturated ole
yl oleate preponderated in 75 mg liquid wax eaters (280 mg lipid extra
ct) recovered from 100-ml cultures of Acinetobacter B-14920 supplement
ed with 810 mg oleic acid-oleyl alcohol. With soybean oil instead of o
leic acid, wax esters (260 mg) were increased to approximately 50% of
the lipid extract, Production of wax esters by cultures supplemented w
ith combined fatty (C-8-C-18) alcohols and acids su sts a coordinated
synthesis whereby the exogenous alcohol remains unaltered, and the fat
ty acid is partially oxidized with removal of C-2 units before esterif
ication. Consequently, C-8-C-18 primary alcohols control chain lengths
of the wax esters. Exogenous fatty acids are presumed to enter an int
racellular oxidation pool from which is produced a homologous series o
f liquid wax esters.
