Disclosed are methods of producing carotenoid compounds in a methylotrophic bacterial host cell. Such a host cell may be an unmodified Methylobacterium, spontaneous mutant, or transformed cell, any of which exhibit favorable properties, such as overproduction of carotenoid compounds, increased carbon flux, improved growth, or the production of additional nutrients, such as protein, vitamins, antioxidants, or fatty acids. Also disclosed are feed compositions for use in aquaculture, or as animal feed, or as human nutritional supplements containing processed or unprocessed biomass from such cells, as are methods of preparation of the feed compositions.
本发明公开了在养甲细菌宿主细胞中生产类胡萝卜素化合物的方法。这种宿主细胞可以是未修饰的甲基细菌、自发突变体或转化细胞,其中任何一种都表现出有利的特性,例如类胡萝卜素化合物的过度生产、碳通量的增加、生长的改善或额外营养物质的生产,例如蛋白质、维生素、抗氧化剂或脂肪酸。还公开了用于水产养殖的饲料组合物,或作为动物饲料的饲料组合物,或作为人类营养补充剂的饲料组合物,其中含有来自此类细胞的加工或未加工生物质,以及饲料组合物的制备方法。
