Abstract:
Increasing space-time-yield, carbon-conversion-efficiency and carbon substrate flexibility in the production of fine chemicals The inventors of the current invention have found a surprising positive effect of increased cAMP levels and/or manipulating the PTS system on the space-time-yield, carbon-conversion-efficiency and carbon substrate flexibility of fine chemical production of a host organism. This was achieved by de-regulating adenylate cyclase cyaa by deleting the C-terminal regulatory region leading to increased cAMP levels or deleting the Crr protein activity (carbohydrate repression resistance) which regulates the carbohydrate utilization system. Both lead to increased 2-fucosyllactoe and 6-sialyllactose production (human milk oligosaccharides) and increase carbohydrate usage.

Abstract:
The present invention relates to a method of producing riboflavin in a genetically modified organism of the genus Eremothecium, wherein said genetic modification is linked to the fatty acid uptake and/or beta-oxidation pathway of said organism, comprising growing said organisms in a culture medium and isolating riboflavin from the culture medium. The invention further relates to a method of providing a riboflavin accumulating organism belonging to the genus Eremothecium by genetically modifying said organism, to organisms obtained by such a method, as well as the use of such genetically modified organisms for increasing the accumulation of riboflavin.
