alpha,omega-Dicarboxylic acid accumulation by acyl-CoA oxidase deficient mutants of Yarrowia lipolytica.


PMID 16086248

Abstract

alpha,omega-Dicarboxylic acid accumulation from alkanes and alkane degradation intermediates was investigated using Yarrowia lipolytica wild type strain W29 as well as a double, a triple and a quadruple POX-deleted strains. Six genes, POX1 through POX6, encode six acyl-CoA oxidase isozymes in Y. lipolytica. All the strains accumulated dodecanedioic acid (5-20 mg ml(-1)) from the diterminal functionalised 1,12-dodecane diol and 12-hydroxdodecanoic acid. The quadruple-deleted strain was the only strain that was able to accumulate dioic acids from C16 alkanol and monocarboxylic acid as well as from C12, C14 and C16 alkanes (maximum 8 mg ml(-1) from dodecane).
