    摘要: 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.

    摘要: A method for the facile and inexpensive inducible expression of heterologous genes has been discovered. The yhcS regulator gene has been found to be inducible by aromatic carboxylic acids and to alter the expression of operons in the LysR gene family, including the yhcRQP operon, common in enteric bacteria. Heterologous nucleic acid molecules placed under the control of yhcs responsive promoters may be overexpressed in response to the presence of inexpensive aromatic carboxylic acids.
