METHYLOTROPHS FOR AQUACULTURE AND ANIMAL FEED

摘要

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.
