Larry Cameron Anthony, Lori Ann Maggio Hall: Enhanced pyruvate to acetolactate conversion in yeast. Butamax™ Advanced Biofuels, Christine M Lhulier, March 11, 2014: US08669094 (16 worldwide citation)

A high flux in conversion of pyruvate to acetolactate was achieved in yeast through expression of acetolactate synthase in the cytosol in conjunction with reduction in pyruvate decarboxylase activity. Additional manipulations to improve flux to acetolactate are reduced pyruvate dehydrogenase activit ...

Michael G Bramucci, Andrew C Eliot, Lori Ann Maggio Hall, Charles E Nakamura: Butanol dehydrogenase enzyme from the bacterium. Butamax Advanced Biofuels, Christine M Lhulier, April 8, 2014: US08691540 (15 worldwide citation)

From a bacterial strain isolated from an environmental sample, after enrichment in medium containing 1-butanol as the carbon source, a new enzyme with butanol dehydrogenase activity was identified. The enzyme can convert butyraldehyde to 1-butanol, isobutyraldehyde to isobutanol, as well as 2-butano ...

Michael G Bramucci, Robert A Larossa, Dana R Smulski: Yeast with increased butanol tolerance involving high osmolarity/glycerol response pathway. Butamax Advanced Biofuels, Christine M Lhulier, June 4, 2013: US08455225 (15 worldwide citation)

Increasing tolerance to butanol in yeast has been accomplished by increasing activity of the high osmolarity/glycerol response pathway. Yeast with increased expression of PBS2p, a mitogen activated protein kinase kinase of the MAPK module of the high osmolarity/glycerol response pathway may be used ...
