Robert B Hespell, Herbert A Wyckoff, Bruce S Dien, Rodney J Bothast: Stabilization of pet operon plasmids and ethanol production in bacterial strains lacking lactate dehydrogenase and pyruvate formate lyase activities. The United States of America represented by the Secretary of Agriculture, M Howard Silverstein, Randall E Deck, John D Fado, August 28, 2001: US06280986 (60 worldwide citation)

Recombinant bacteria are disclosed which are transformed with heterologous DNA coding for alcohol dehydrogenase (adh) and pyruvate decarboxylase (pdc), and which are effective for use in the production of ethanol, but which do not require the presence of antibiotics in the culture medium to maintain ...

Nancy N Nichols, Maria J Lopez, Bruce S Dien, Rodney J Bothast: fungus, Culture containing biomass acid hydrolysate and. The United States of America represented by the Secretary of Agriculture, John D Fado, Curtis P Ribando, Lesley Shaw, June 27, 2006: US07067303 (7 worldwide citation)

Agricultural biomass hydrolysate is detoxified by culturing in the presence of the fungus Coniochaeta ligniaria (teleomorph) or its Lecythophora (anamorph) state. This organism is capable of significantly depleting the toxicant levels of furans, particularly furfural and 5-hydroxymethylfurfural. A n ...

The United States of America represented by the Secretary of Agriculture, Board of Trustees of Michigan State University, John D Fado, David L Marks, Lesley Shaw, March 29, 2016: US09297027

Several mutated strains of Scheffersomyces stipitis are generated by repetitive culturing of the parent strain on two types of concentrated hydrolyzates and with ethanol-challenged xylose-fed continuous culture. Isolates collected from various enriched populations are screened and ranked based on re ...
