石油酵母在补充氨、金属盐和大量氧气的石油－水乳剂中进行发酵，可制得石油酵母，当前已采用下述两种不同的加工方法：①纯石蜡，在石油中提取的石蜡在无菌的条件下发酵，石蜡几乎全被酵母消耗，将酵母分离，干燥，不用精炼即可。②原油，在加工过程中，石蜡（占石油１０... Oil yeast in oil-water emulsion supplemented with ammonia, metal salts and large amounts of oxygen can be fermented to produce oil yeast. Currently, the following two different processing methods have been used: ① pure paraffin, paraffin wax extracted from petroleum Fermentation under the conditions of bacteria, paraffin wax almost all consumed by yeast, the yeast separation, drying, can not be refined. ② crude oil, in the process of processing, paraffin (accounting for oil 10 ...
