    Abstract: Recombinant bacteria capable of producing glycerol and glycerol-derived products from sucrose are described. The recombinant bacteria comprise in their genome or on at least one recombinant construct: a nucleotide sequence encoding a polypeptide having sucrose transporter activity; a nucleotide sequence encoding a polypeptide having fructokinase activity; and a nucleotide sequence encoding a polypeptide having sucrose hydrolase activity. These nucleotide sequences are each operably linked to the same or a different promoter. These recombinant bacteria are capable of metabolizing sucrose to produce glycerol and/or glycerol-derived products such as 1,3-propanediol and 3-hydroxypropionic acid.

  • Patent number: 7700328
    Abstract: An enteric bacterial strain was engineered to over-produce L-tyrosine using a one-step method. The pheA-tyrA chromosomal region of the bacterial genome was replaced with an engineered chromosomal segment, resulting in inactivation of the pheA coding region and strong expression of the tyrA coding region, resulting in high levels of L-tyrosine production.
