  • Process for producing transglutaminase by microorganism
    Patent number: 6472182
    Abstract: The present invention provides a process for producing a transglutaminase, which comprises culturing microorganisms of any of the genus Micrococcus, Clostridium, Torulopsis, Rhizopus and Monascus in a medium to produce the intended transglutaminase in the medium or in the cells of the microorganisms and then isolating the transglutaminase, and a process for producing a gelled proten with the thus-obtained transglutaminase. According to the process of the present invention, transglutaminase can be rapidly produced at a low cost.
