Abstract
The invention provides methods of cultivating oil-bearing microbes using cellulosic material. Also provided are microorganisms that manufacture non-alcohol-based fuels and fuel feedstocks through a process of converting cellulosic materials into oils. Also provided are compositions comprising depolymerized cellulosic materials and oil-bearing microbes. Some methods of microbial fermentation are provided that comprise combining depolymerized cellulosic materials with other non-cellulosic feedstocks to enhance the economics of renewable fuel manufacturing. Particular advantages of the processes provided herein include production of oils rather than alcohols through cellulosic processes. Additional advantages include methods for manufacturing high nutrition oils from non-edible feedstocks such as wood chips, switchgrass, and bagasse.
