摘要:
Methods for the fermentive production of four carbon alcohols are provided. Specifically, butanol, preferably 2-butanol is produced by the fermentive growth of a recombinant bacteria expressing a 2-butanol biosynthetic pathway. The recombinant microorganisms and methods of the invention can also be adapted to produce 2-butanone, an intermediate in the 2-butanol biosynthetic pathways disclosed herein.
摘要:
Recombinant Escherichia coli (E. coli) bacteria that have enhanced acetyl-CoA synthetase activity and the ability to produce glycerol and glycerol-derived products, such as 3-hydroxypropionic acid, methylglyoxal, 1,2-propanediol, and 1,3-propanediol, are described. The recombinant E. coli comprise a promoter operably linked to a nucleotide sequence encoding a polypeptide having acetyl-CoA synthetase enzyme activity, wherein the promoter and nucleotide sequence are each independently either native or non-native.

摘要:
Recombinant microorganisms having an improved ability to co-metabolize in medium both fructose and glucose are described. The recombinant microorganisms comprise a promoter operably linked to a native or non-native nucleotide sequence that encodes a fucose:H+ symporter polypeptide. The recombinant microorganisms are useful for the production of a variety of products including glycerol and glycerol derivatives such as 1,3-propanediol and 3-hydroxypropionic acid.
摘要:
Methods for the fermentative production of four carbon alcohols is provided. Specifically, butanol, preferably isobutanol is produced by the fermentative growth of a recombinant bacterium expressing an isobutanol biosynthetic pathway.
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.
