    摘要: Increasing tolerance to butanol in yeast has been accomplished by decreasing activity of Pdr5p encoded by an endogenous PDR5 gene. A deletion mutation of the PDR5 gene led to improved growth yield in the presence of butanol. Yeast cells with reduced Pdr5p activity, or other multidrug resistance ATP-binding cassette transporter protein activity encoded by CDR1 or BFR1, and a butanol biosynthetic pathway may be used for improved butanol production.

    摘要: Recombinant bacteria capable of metabolizing sucrose are described. The recombinant bacteria comprise in their genome or on at least one recombinant construct: a nucleotide sequence from Bacillus licheniformis ATCC® 14580 encoding a polypeptide having sucrose transporter activity and a nucleotide sequence from Bacillus licheniformis ATCC® 14580 encoding a polypeptide having sucrose hydrolase activity. These nucleotide sequences are each operably linked to the same or a different promoter. Recombinant bacteria capable of metabolizing sucrose to produce glycerol and/or glycerol-derived products such as 1,3-propanediol and 3-hydroxypropionic acid are also described.

    摘要: Bacteria that are not natural butanol producers were found to have increased tolerance to butanol when the saturated fatty acids content in bacterial cell membrane was increased. Methods for increasing the concentration of saturated fatty acids in the membranes of bacteria that are not natural butanol produces are described whereby tolerance of the bacterial cell to butanol is increased. Saturated fatty acids concentration in the bacterial cell membrane increased upon exogenously feeding saturated fatty acids to cells. Bacterial strains useful for production of butanol are described herein having modified unsaturated fatty acid biosynthetic pathway.

    摘要: The present invention relates to the generation and use of a cellular array or a cellular array in combination with other genome-registered arrays (an array of arrays) for the determination of gene function and/or perturbation mode of action. Each cellular array consists of a number of microbial strains. Each strain comprises one reporter gene fusion made up of a gene or gene fragment operably linked to a reporter gene. Each gene or gene fragment has been “registered” or mapped to a specific location in the genome of the organism. The genome-registered collection of the invention may be used to determine alterations in gene expression under a variety of conditions. Such collections are amenable to rapid assay and may be used to confirm, correct or augment data generated from DNA micro array technology.
