  • Phytase variants
    Patent number: 6689358
    Abstract: The present invention relates to phytase variants, their preparation and uses, which phytase variants, when aligned according to FIG. 1, are amended as compared to a model phytase in at least one of a number of positions. Preferred model phytases are basidiomycete and ascomycete phytases, such as Peniophora phytase and Aspergillus phytases. Preferred phytase variants exhibits amended activity characteristics, such as improved specific activity and/or improved thermostability.

  • Production of (-)trans-2,3-epoxysuccinic acid by fermentation
    Patent number: 5015579
    Abstract: A method for producing (-)trans-2, 3-epoxysuccinic acid, which can be used as a good starting material for the sythesis of optically active compounds such as optically specific single .beta.-lactam antibiotics, characterized in that filamentous fungi capable of producing (-)trans-2,3-epoxysuccinic acid are cultured in liquid medium while either ammonia, sodium hydroxide or potassium hydroxide is added to maintain the culture medium in a pH range of 5.0 to 7.5 throughout the culturing period.

  • Strains of Aspergillus and use thereof to produce amylolytic enzymes
    Patent number: 4593005
    Abstract: A novel strain Aspergillus K27 belonging to genus Aspergillus which has the same taxonomical characteristics as those of Aspergillus fumigatus except that(1) its conidiophore is colorless and(2) its growing temperature range is between 10.degree. and 55.degree. C., which produces amylolytic enzymes which can hydrolyze alpha-amylase resistant starch as well as usual starch.
