    摘要: A method for high-density culture of a microorganism is proposed. This method is characterized by adjusting the cultivation temperature to a level lower than the optimum temperature for growth thereby causing the specific growth rate of the microorganism to reach a level of not more than 20% of the specific growth rate at the optimum temperature for growth. By this method of culture, it is made possible to culture the microorganism at a very high density. Further, this method of culture enables a useful substance, particularly an active type recombinant protein, to be produced in a large amount at a very low cost with high efficiency.

    摘要: This invention relates to a novel high-activity modified S-hydroxynitrile lyase (SHNL). More particularly, this invention relates to novel high-activity modified SHNL that is obtained by substituting amino acids at given sites (14, 44, 66, 94, 103, 118, 122, 125, 127, 129, 147, 148, 152, 212, and 216) or inserting amino acid at a given site (between amino acids 128 and 129) of the amino acid sequence (SEQ ID NO: 2) of wild-type SHNL.

    摘要: A method for efficient production of an S-hydroxynitrile lyase by gene recombination using Escherichia coli is provided. A gene is formed by altering a codon in an S-hydroxyniitrylase gene originating in cassava (Manihot esculenta Crantz) without changing the amino acid sequence thereof till the frequency of codon usage wholly with an amino acid in Escherichia coli reaches a level of not less than 5%. According to the method for the production of an S-hydroxynitrile lyase by the use of the gene, the S-hydroxynitrile lyase can be produced in a large amount with an unusually high yield.
