摘要:
The instant disclosure is generally related to microbial fermentation, grain processing and ethanol production. Certain embodiments of the disclosure are therefore related to starch-containing materials and the microbial fermentation of such starch-containing materials for the production ethanol. More particularly, certain embodiments are related to novel protease mixtures comprising an aspartic protease and a serine protease for use in processing such starch-containing materials in starch to ethanol fermentation processes described herein.
摘要:
Described is yeast having reduced acetate production as a consequence of expressing selected heterologous acetyl-Co synthase (ACS) enzymes. Such yeast may further be modified to reduce glycerol and/or increased ethanol production. The yeast is useful for producing ethanol from carbohydrate-containing substrates.
摘要:
Described are methods for increasing the expression of a transgene in eukaryotic cells by reducing RNA interference (RNAi), and variant cells produce by the method. The methods and variant cells are useful, for example, for the efficient production of therapeutic and industrial polypeptides in eukaryotic cells.
摘要:
Described are compositions and methods relating to a fungal cutinase cloned from Magnaporthe grisea , polynucleotides encoding the cutinase, and methods of use thereof. The compositions and methods have particular application in detergent cleaning compositions and synthesis reactions.
摘要:
The invention provides methods for expression of a catalase enzyme in a Trichoderma host cell. In one embodiment, the catR gene from Aspergillus niger is expressed in Trichoderma reesei , resulting in improved yields of catalase enzyme in comparison with expression of catR in A. niger .
摘要:
Described are compositions and methods relating to modified yeast that over-express protein phosphatases associated with the HOG pathway. The yeast produces an increased amount of ethanol and deceased amount of glycerol compared to parental cells. Such yeast is particularly useful for large-scale ethanol production from starch substrates.
摘要:
Described are composition and methods relate to reducing the redox imbalance in anaerobically growing yeast with attenuated glycerol production by re-engineering the pathway for Ac-CoA biosynthesis.
摘要:
The invention features methods for producing isoprene from cultured cells. The invention also provides compositions that include these cultured cells.
