Pseudomonas citronellolis

Fall RR, JI Brown, TL Schaeffer (1979) Enzyme recruitment allows the biodegradation of recalcitrant branched hydrocarbons by Pseudomonas citronellolis. Appl Environ Microbiol 38 715-722. 

Fall has studied the capability of fourteen species of microorganisms to grow on methoprene as sole carbon source. One of these organisms, Cladosporium resinae, was able to utilize methoprene as sole carbon source, while another. Pseudomonas citronellolis, was similarly able to utilize 7-methoxycitronellic acid. (41).

The first data about the bioconversion of farnesol date back to the sixties its degradation pathway is similar to that of geraniol and nerol. Seubert [139] showed that the degradation of farnesol by Pseudomonas citronellolis proceeds through the oxidation of C-l to give famesic acid, followed by carboxylation of the -methyl group. Subsequently, the 2,3-double bond of the dicarboxylic acid is hydrated to a 3-hydroxy acid which is then acted upon by a lyase resulting in the formation of a /Tketo acid and acetic acid. The /Tketo acid readily enters the fatty acid oxidation pathway [29].

Pseudomonas citronellolis was found to produce mcl-PHA on many different substrates (Choi and Yoon 1994). Similar to P. fluorescens, this strain also produced unsaturated monomers from unrelated C -C acids up to 9 mol% 3-hydroxy-c -5-dodecenoate and up to 2.6 mol% 3-hydroxy-CM-7-tetradecenoate, with the largest content being (7 )-3-hydroxydecanoate. A novel copolyester, poly(3-hydroxy-7-methyl-6-octenoate-co-3-hydroxy-5-methylhexanoate), was synthesized when P. citronellolis was grown on citronellol (Choi and Yoon 1994).
