Degradation of citronellol, citronellal and citronellyl acetate by Pseudomonas mendocina IBPse 105
The purpose of this work was to stud the biodegradation of citronellol,
citronellal and citronellyl acetate by a soil Pseudomonas mendocina
strain (IBPse 105) isolated from a Cymbopogon windelandi field. This
strain efficiently used citronellol, citronellal, citronellyl acetate
and myrcene as sole source of carbon, but was not able to grow on other
15 monoterpenoids evaluated. Gas chromatography-mass spectrometry
(GC-MS) analysis of metabolites accumulation during P. medocina IBPse
105 growth on citronellol showed that this strain uses the citronellol
catabolic pathway described for other species of the genus. IBPse 105
degradation of citronellyl acetate initiates by its hydrolysis to
citronellol. The mini-Tn5 insertion in mutant IBPse 105-303, impaired
in citronellol degradation, but able to grow on citronellal, was
located in a homologous of the P. aeruginosa atuB gene, that codifies
citronellol deshydrogenase
