The microbial biotransformation of myrcene (302) was described with Diplodia gossypina ATCC 10936 (Abraham et al., 1985). The main reactions were hydroxylation, as shown in Figure 19.1. On oxidation, myrcene (302) gave the diol (303) (yield up to 60%) and also a side product (304) that possesses one carbon atom less than the parent compound, in yields of l%-2%. 

Metabolic pathways of myrcene (302) and citronellene (309) by microorganisms and insects are summarized in Figure 14.205. i-Myrcene (302) was metabolized with Diplodia gossypina ATCC 10936 (Abragam et al., 1985) to the diol (303) and a side-product (304). P-Myrcene (302) was metabolized with Ganoderma applanatum, Pleurotus flabellatus, and Pleurotus sajor-caju to myrcenol (305) (2-methyl-6-methylene-7-octen-2-ol) and 306 (Busmann and Berger, 1994).
