    摘要: One aspect of the invention relates to a genetically modified thermophilic or mesophilic microorganism, wherein a first native gene is partially, substantially, or completely deleted, silenced, inactivated, or down-regulated, which first native gene encodes a first native enzyme involved in the metabolic production of an organic acid or a salt thereof, thereby increasing the native ability of said thermophilic or mesophilic microorganism to produce ethanol as a fermentation product. In certain embodiments, the aforementioned microorganism further comprises a first non-native gene, which first non-native gene encodes a first non-native enzyme involved in the metabolic production of ethanol. Another aspect of the invention relates to a process for converting lignocellulosic biomass to ethanol, comprising contacting lignocellulosic biomass with a genetically modified thermophilic or mesophilic microorganism.

    摘要: A recombinant flavocytochrome b2 (FCb2), comprising a mature FCb2 peptide sequence of a native FCb2, or a functionally active variant of said mature FCb2 peptide sequence, wherein the N-terminus of said mature FCb2 peptide sequence consists of a truncated signal peptide sequence replacing the native signal peptide sequence, and wherein said truncated signal peptide sequence is of the following structure from N- to C-terminus: i. a methionine; ii. optionally a tag sequence; iii. an amino acid sequence of a length of 0-9 amino acids of the native signal peptide sequence, corresponding to the amino acid sequence up to 9 amino acids directly upstream of the I/L/V-x-N/A/L motif of the native signal peptide sequence of FCb2; and iv. the I/L/V-x-N/A/L motif, which can be of number 0, 1, or can be partially truncated, wherein if the number is 0 or the I/L/V-x-N/A/L is partially truncated, the length of the amino acid sequence of iii. is 0, wherein the amino acid sequence of said recombinant FCb2 is different from SEQ ID NO: 145.
