A laboratory isolate of Aspergillus niger elaborated considerable quantities of exocellular amylolytic enzymes. The enzymes exhibited a highly thermophilic nature. The culture filtrate exhibited two pH optima for dextrinogenic and one for saccharifying activity. Electrophoretic studies of the culture filtrate revealed three major proteins, two exhibiting α‐amylase and one amyloglucosidase activity.
