Bacillus firmus synthesizes C30 carotenoids via farnesyl pyrophosphate, forming apophytoene as the first committed step in the pathway. The products of the pathway is methyl 4'-[(6-O-acyl-glycosyl)oxy]-4,4'-diapolycopen-4-oic acid and 4,4'-diapolycopen-4,4'-dioic acid with putative glycosyl esters

the biosynthesis of 4,4'-diaponeurosporene starts with the condensation of two molecules of farnesyl diphosphate by dehydrosqualene synthase CrtM, the reaction product of this enzyme is dehydrosqualene and not squalene. Dehydrosqualene, i.e.4,4'-diapophytoene, is successively dehydrogenated by desaturase CrtN to form the yellow main intermediate 4,4'-diaponeurosporene
