  • Publication number: 20230042456
    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.
