    摘要: This disclosure describes genetically modified photosynthetic microorganisms, e.g., Cyanobacteria, that overexpress an acyl carrier protein (ACP), an acyl-ACP synthase (Aas), or both, optionally in combination with one or more overexpressed or exogenous lipid biosynthesis proteins, and/or one or more overexpressed or exogenous glycogen breakdown proteins. Exemplary biosynthesis proteins include diacyglycerol acyltransferases, thioesterases, phosphatidate phosphatases, phospholipases, triacylglycerol (TAG) hydrolases, fatty acyl-CoA synthetases, and/or acetyl-CoA carboxylases, including combinations thereof. Also included are photosynthetic microorganisms comprising mutations or deletions in a glycogen biosynthesis or storage pathway, which accumulate a reduced amount of glycogen under reduced nitrogen conditions as compared to a wild type photosynthetic microorganism. The modified photosynthetic microorganisms provided herein are capable of producing increased amounts of lipids such as fatty acids and/or synthesizing triglycerides.

    摘要: The invention relates to a method of generating a recombinant host strain for producing phenol, comprising the steps of a) providing a host comprising chorismate, b) transforming the host with a first nucleic acid sequence comprising ubiC (SEQ ID NO: 1) encoding chorismate lyase that converts chorismate to 4-hydroxybenzoate, and c) transforming the host with a second nucleic acid sequence encoding an oxygen-tolerant 4-hydroxybenzoate decarboxylase that converts 4-hydroxybenzoate to phenol, thereby generating a recombinant host that is capable of producing phenol under aerobic conditions, wherein step b) and step c) are carried out simultaneously or sequentially. The invention also provides the recombinant host strain for producing phenol obtainable by the aforementioned method, as well as a method of producing phenol in the recombinant host strain.
