20120322117 | ENZYMATIC PRODUCTION OF ALCOHOL ESTERS FOR RECOVERY OF DIOLS PRODUCED BY FERMENTATION - Diols produced in fermentation are processed in broth by esterification of the product diol with a carboxylic acid (e.g., fatty acid) and a catalyst (e.g., lipase) capable of esterifying the product diol, such as 1,3-propanediol, with the carboxylic acid to form the diol esters. The diol esters can be extracted from the broth, and the product diol recovered from the diol esters. The carboxylic acid can also serve as an extractant for removal of the diol esters from the fermentation medium. | 12-20-2012 |
20130040340 | PRODUCTION OF ALCOHOL ESTERS IN SITU USING ALCOHOLS AND FATTY ACIDS PRODUCED BY MICROORGANISMS - Fatty acid alcohol esters that may be used as biodiesel are synthesized from microbially produced alcohol and fatty acids using an in situ process. The process utilizes a catalyst capable of esterifying the alcohol and fatty acid products of microorganisms, which are produced from renewable resources. | 02-14-2013 |

20140142352 | BUTANOL PURIFICATION - Provided herein are processes for adjusting a fermentation medium to reduce the activity of one or more carboxylic acids. The processes comprise (a) providing a recombinant microorganism comprising an engineered butanol biosynthetic pathway, (b) contacting the recombinant microorganism with a fermentation medium whereby butanol is produced and wherein the fermentation medium comprises one or more carboxylic acids, and (c) adjusting the fermentation medium to reduce the activity of the one or more carboxylic acids. Also provided are processes for reducing the activity of one or more carboxylic acids in a feed. The processes comprise (a) providing a feed from a fermentation vessel, wherein the feed comprises a composition produced by a recombinant microorganism comprising an engineered butanol biosynthetic pathway, wherein the composition comprises butanol, water, and one or more carboxylic acids; and (b) adjusting the feed, wherein adjusting the feed reduces the activity of the one or more carboxylic acids. | 05-22-2014 |

20140186906 | RECOMBINANT MICROBIAL CELLS THAT PRODUCE AT LEAST 28% EICOSAPENTAENOIC ACID AS DRY CELL WEIGHT - Recombinant microbial cells are disclosed herein that produce an oil comprising at least 28 percent eicosapentaenoic acid (EPA) measured as a weight percent of dry cell weight. These cells may comprise a polynucleotide sequence encoding an active acyl-CoA:lysophosphatidylcholine acyltransferase (LPCAT) comprising at least one amino acid mutation in a membrane-bound O-acyltransferase motif. In addition, the cells may comprise a down-regulation of an endogenous polynucleotide sequence encoding Sou2 sorbitol utilization protein, and/or one or more polynucleotides encoding phospholipid:diacylglycerol acyltransferase (PDAT), delta-12 desaturase, a dihomo-gamma-linolenic acid (DGLA) synthase multizyme, delta-8 desaturase, malonyl-CoA synthetase (MCS), or acyl-CoA:lysophosphatidic acid acyltransferase (LPAAT). Also disclosed are methods of using the recombinant microbial cells to produce oil containing omega-3 polyunsaturated fatty acids such as EPA. | 07-03-2014 |
20140220645 | DOWN-REGULATION OF A POLYNUCLEOTIDE ENCODING A SOU2 SORBITOL UTILIZATION PROTEIN TO MODIFY LIPID PRODUCTION IN MICROBIAL CELLS - Recombinant microbial cells are disclosed herein that comprise (i) a down-regulation of an endogenous polynucleotide sequence encoding Sou2 sorbitol utilization protein, and (ii) a polyunsaturated fatty acid (PUFA) biosynthetic pathway. The down-regulation of the polynucleotide sequence encoding Sou2 sorbitol utilization protein can increase the lipid content of the microbial cells and/or decrease the total amount of sugar alcohols produced by the microbial cells. Also disclosed are methods of using the recombinant microbial cells to produce oil containing omega-3 polyunsaturated fatty acids such as EPA. | 08-07-2014 |
20140273129 | GLYCEROL 3- PHOSPHATE DEHYDROGENASE FOR BUTANOL PRODUCTION - Provided herein are glycerol-3-phosphate dehydrogenase (GPD) enzymes with increased K | 09-18-2014 |
20140273130 | COMPETITIVE GROWTH AND/OR PRODUCTION ADVANTAGE FOR BUTANOLOGEN MICROORGANISM - Provided herein are recombinant yeast host cells and methods for their use for production of fermentation products. Host cells provided herein comprise a pyruvate-utilizing pathway and a competitive growth advantage over other microorganisms in solution. | 09-18-2014 |
