Abstract

A suite of six sterols, lanosterol, lanost-8(9)-en-3beta-ol, 4, 4-dimethylcholesta-8(14),24-dien-3beta-ol, 4, 4-dimethylcholest-8(14)-en-3beta-ol, 4-methylcholesta-8(14), 24-dien-3beta-ol and 4-methylcholest-8(14)-en-3beta-ol, were identified in the psychrophilic methanotrophic bacterium, Methylosphaera hansonii. Their presence suggests that the capacity for sterol biosynthesis in methanotrophic bacteria is limited to the family Methylococcaceae but which have widely different optimal growth temperatures.

摘要

在嗜冷甲烷氧化菌汉氏甲基球形菌（Methylosphaera hansonii）中鉴定出了一组六种甾醇，即羊毛甾醇、羊毛甾-8(9)-烯-3β-醇、4,4-二甲基胆甾-8(14),24-二烯-3β-醇、4,4-二甲基胆甾-8(14)-烯-3β-醇、4-甲基胆甾-8(14),24-二烯-3β-醇和4-甲基胆甾-8(14)-烯-3β-醇。它们的存在表明，甲烷氧化菌中甾醇生物合成的能力仅限于甲基球菌科，但这些菌具有广泛不同的最适生长温度。
