A method is disclosed for producing 3-hydroxypropionaldehyde (3-HPA) from glycerol by culturing the bacterium Klebsiella pneumoniae having the identifying characteristics of NRRL B-4011, under aerobic conditions, in an aqueous nutrient medium containing glycerol and a compound that causes 3-HPA to be accumulated by blocking the conversion of 3-HPA to trimethylene glycol. This process is particularly useful for the production, from renewable resources, of acrylic acid, an industrially important plymerizable monomer used in the manufacture of synthetic polymers and plastics and which is presently derived from fossil fuel sources.

Production of 3-hydroxypropionaldehyde from glycerol by Klebsiella

A method is disclosed for converting D-xylose to ethanol relying on the unique ability of the yeast Pachysolen tannophilus to ferment this five-carbon sugar without the use of added enzymes. This process will be particularly useful in the production of ethanolic fuel from plant biomass.
