Renewable fuels produced from oleaginous microorganisms

摘要

Disclosed herein are methods of manufacturing renewable chemicals through the manufacture of novel triglyceride oils followed by chemical modification of the oils. Methods such as transesterification, hydrogenation, hydrocracking, deoxygenation, isomerization, interesterification, hydroxylation, hydrolysis and saponification are disclosed. Novel oils containing fatty acid chain lengths of C8, C10, C12 or C14 are also disclosed and are useful as feedstocks in the methods of the invention.

主权项

1. A fuel prepared by a process, the process comprising:
(a) providing a triglyceride oil isolated from a cultivated oleaginous microorganism, wherein the oleaginous microorganism comprises an exogenous fatty acyl-ACP thioesterase gene that encodes a fatty acyl-ACP thioesterase having hydrolysis activity towards one or more fatty acyl-ACP substrates of chain length 8 to 18 carbon atoms, and produces triglyceride oil enriched in esterified fatty acids of chain length 8 to 18; (b) performing one or more chemical reactions on the triglyceride oil to produce the fuel; and (c) separating and recovering the fuel from the products of the chemical reaction mixture after performing step (b).
