The yellow-pigmented Cellulomonas biazotea, ATCC 486, contains a mixture of carotenoids. The principal compound is a decapreno carotenoid (C50H72O2) tentatively characterized as 2,2'-bis(4-hydroxy-3-methyl-2-butenyl)-gamma,gamma-carotene on the basis of electronic absorption, infrared, proton magnetic resonance, and mass spectrometries. The carotenoid is presumed to be identical to sarcinaxanthin from Sarcina lutea pro-synon. Micrococcus luteus and, therefore, is isomeric with decaprenoxanthin from Cellulomonas dehydrogenans.
黄色色素的拜氏纤维单胞菌（Cellulomonas biazotea）ATCC 486含有多种类胡萝卜素。主要化合物是一种癸异戊二烯类胡萝卜素（C50H72O2），根据电子吸收光谱、红外光谱、质子磁共振光谱和质谱分析，初步鉴定为2,2'-双（4-羟基-3-甲基-2-丁烯基）-γ,γ-胡萝卜素。据推测，该类胡萝卜素与藤黄八叠球菌（Sarcina lutea pro-synon. 藤黄微球菌Micrococcus luteus）的藤黄八叠球菌黄素相同，因此与脱氢纤维单胞菌（Cellulomonas dehydrogenans）的癸异戊二烯叶黄素是同分异构体。
