Screening of High Lipid-Producing Fungus from Marine Environment and Studies on the Optimization of Fermentation Conditions

Abstract

微生物油脂(microbialoils)又称单细胞油脂(singlecelloil,SCO),即微生物以碳水化合物、碳氢化合物和普通油脂为碳源、氮源、辅以无机盐生产的油脂和另一些有商业价值的脂质。随着人口的增长、社会的进步使油脂需求量与自然资源短缺的矛盾日益加剧,环境污染日趋严重,开发新型油脂资源及清洁能源是当务之急。微生物生产油脂具有原料来源丰富、可再生、成本低、周期短、环境友好等优点,已引起人们的高度关注。开展微生物油脂的研究对解决人类面临的资源短缺、环境恶化等现实问题具有重要意义。 本论文从产油脂菌株的筛选开始,对高产菌株进行理化诱变以获得高产突变株,对菌株产油脂发酵工艺条件进行了系统...Microbial oils, referring to oils produced by microorganisms with carbohydrate source(carbohydrates, hydrocarbons and ordinary fats), nitrogen sources and inorganic chemicals, were called single cell oil as well. With the population growth and social progress, the contradiction between demand of oil and shortage of natural resources is increasingly intensifying. On the other hand, the environmenta...学位:工学硕士院系专业:化学化工学院化学工程与生物工程系_生物化工学号:2062009115129
