[Screening of Producers of Proteinases with Fibrinolytic and Collagenolytic Activities among Micromycetes].
Screening for producers of proteinases with fibrinolytic (plasmin-like and plasminogen-activating) and collagenolytic activities-was carried out among 83 strains of microscopic fungi belonging to various ecological groups. Entomopathogenic micromycetes secreted proteinases with higher fibrinolytic and collagenolytic activity than saprotrophic, potentially phytopathogenic, and epiphytic strains. Micromycete strains possessing proteolytic enzymes with collagenase activity were revealed, as well as the strains producing proteinases with plasmin-like activity. None of the strains studied secreted proteinases possessing only plasminogen-activating activity. Tolypocladium inflatum k1 was found to be a producer of extracellular proteinases with high plasminogen-activating, plasmin-like, and collagenolytic activities. The specific plasminogen-activating activity of T. inflatum k1 was shown to be 20% higher than its plasmin-like activity.
