The free-living, hermaphroditic nematode Caenorhabditis briggsae has a nutritional requirement for sterols. It will reproduce indefinitely in a liquid medium containing only bacterial cells (Escherichia coli) and salts if various sterols are present. Several other lipid-soluble materials are ineffective in supporting reproduction.
自由生活的雌雄同体线虫秀丽隐杆线虫对固醇有营养需求。如果存在各种固醇,它将在仅含有细菌细胞(大肠杆菌)和盐的液体培养基中无限繁殖。其他几种脂溶性物质在支持繁殖方面无效。
