P-Isopropyl pimelic acid

Concentrated cell suspension of Pseudomonas sp. strain (PL) was inoculated to the medium containing 1-p-menthene (62) as the sole carbon source. It was degraded to give p-isopropyl pimelic acid (248) and methylisopropyl ketone (251) (Hungund et al, 1970) (Figure 19.48). 

C with agitation and aeration for 4 days yielded camphor (37 ), bomeol (36a ), isobomeol (36b ), a-terpineol (34 ), and P-isopropyl pimelic acid (248 ) (see Figure 14.154). Using modified Czapek-Dox medium and keeping the other conditions the same, the pattern of the metabolic products was dramatically changed. The metabolites were tran -pinocarveol (2 ), myrtenol (S ), a-fenchol (11 ), a-terpineol (34 ), myrtenic acid (7 ), and two unidentified products (see Figure 14.157).
