Using hexane extraction, squalene, its four hydroforms and an unknown orange-yellow coloured compound termed as pigment 462 (since it has a specific absorption maximum in the visible region of the spectrum) were isolated from a thermophylic methane-producing culture of Methanobacillus kuzneceovii. Pigment 462 is rapidly reduced by sodium borohydride and is readily oxidized by air oxygen; its functional group is the keto group. The physico-chemical properties of pigment 462 indicate that the pigment is one of the components of the electron transport chain of methane-producing bacteria and is localized in the membrane.
通过己烷萃取，从库氏甲烷杆菌的嗜热产甲烷培养物中分离出了角鲨烯、其四种氢化形式以及一种名为色素462的未知橙黄色化合物（因其在光谱的可见光区域有特定的最大吸收峰）。色素462能被硼氢化钠迅速还原，并易被空气中的氧气氧化；其官能团为酮基。色素462的物理化学性质表明，该色素是产甲烷细菌电子传递链的组成成分之一，且定位于细胞膜中。
