油和脂肪 oils and fats ◼ Oil and fats are also used as carbon sources because some microbes contain lipase (脂肪酶) ◼ Fat →glycerol(甘油) and fatty acids → oxidize → CO2+ water, releasing much energy ◼ Providing enough O2 is important. ◼ 常用的油：豆油、菜子油、猪油、鱼油、棉子 油等

有机酸 organic acids ◼ Some microbes can use organic acids as carbon sources, such as lactic acid, citric acid, acetic acid. ◼ pH of cultural medium will increase. CH3COONa + O2 → 2CO2 + H2O + NaOH

烃和醇类 hydrocarbon and ethanol ◼ 石油及裂解产物如正烷烃也可用作 carbon sources. ◼ 自然界中能同化乙醇的微生物和能同化糖质的 微生物一样普遍
