Purification and characterization of a lipolytic enzyme active at low temperature from Norwegian Typhula ishikariensis group III strain

Abstract

An extracellular lipolytic enzyme active at low temperature was purified from the culture filtrate of the snow mold fungus, Typhula ishikariensis group III, strain 6-1-1. The molecular mass of enzyme was approximately 83 kDa (SDS-PAGE). The lipolytic enzyme was most active for p-nitrophenyl palmitate at 30 –C (pH 9.0). The lipolytic activity was 23.4% of the maximum at 4 –C, the temperature of culture. Thus, the isolated T. ishikariensis lipolytic enzyme is thought to represent a new member of a group of enzymes active at low temperature.
