摘要:
By administering sterilized bacterial cells obtained by heat treating cells of a coryneform bacterium or an enterobacterium under a condition of pH 2 to 5 at 90 to 120°C for 3 minutes to 4 hours, or a feed containing such sterilized bacterial cells to a mammal, fowl, fish, or crustacean, immunity of these animals is enhanced.
摘要:
A process for producing transglutaminases which comprises incubating a microorganism belonging to the genus Micrococcus, Clostridium, Torulopsis, Rhizopus or Monascus in a medium, thus producing the target transglutaminase in the medium or cells and then harvesting the transglutaminase; and a process for producing gel substances by using the transglutaminases. This process makes it possible to economically and quickly produce transglutaminases.
