Patent number: 6689358Abstract: 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.Type: GrantFiled: February 26, 2002Date of Patent: February 10, 2004Assignee: Novozymes A/SInventors: Allan Svendsen, Søren Flensted Lassen, Dirk Kostrewa, Luis Pasamontes, Martin Lehmann, Andrea Tomschy, Adolphus Van Loon, Kurt Vogel, Markus Wyss

Patent number: 5196327Abstract: A mixture of derivatives of 2-amino-3,4,5,14-tetrahydroxy-6-eicosenoic acid has been isolated from a culture medium after cultivation of microorganisms belonging to the genus Aspergillus. The compounds are useful as antifungal agents.Type: GrantFiled: May 8, 1991Date of Patent: March 23, 1993Assignee: Merck & Co., Inc.Inventors: Maria B. Lopez, Richard L. Monaghan
-
Patent number: 5015579Abstract: 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.Type: GrantFiled: February 10, 1987Date of Patent: May 14, 1991Assignee: Takeda Chemical Industries, Ltd.Inventors: Takamasa Yamaguchi, Ikuo Nogami
-
Patent number: 4593005Abstract: 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.Type: GrantFiled: August 6, 1984Date of Patent: June 3, 1986Assignee: Daikin Industries, Ltd.Inventor: Susumu Hizukuri
-
Patent number: 4220719Abstract: A process for producing Coenzyme Q.sub.10 which comprises cultivating a microorganism belonging to genus Cryptococcus, Rhodotorula, Sporobolomyces, Torulopsis, Sporidiobolus, Oosporidium, Aspergillus, and Cladosporium in a culture medium to which isopentenyl alcohol is added and recovering the thus formed Coenzyme Q.sub.10.Type: GrantFiled: March 7, 1979Date of Patent: September 2, 1980Assignee: Ko AidaInventors: Ko Aida, Kinya Uchida, Izumi Kawada, Hideichi Ito
