Cellulolytic and Pectinolytic Enzymes of Some Selected Heat Resistant Fungi

Abstract

Ten heat resistant fungi, Arthrinium sp., Aspergillus cejpii, A. nidulans, A. spinosus, Byssochlamys nivea, Hamigera avellanea, Talaromyces trachyspermus, T. barcinensis, T. ucrainicus, and Trichoderma asperellum were tested on their ability to produce cellulolytic and pectinolytic enzymes. Except for B. nivea and A. cejpii, all species secreted cellulolytic enzymes in the used cup plate assay. All isolates produced considerable levels of pectinolytic enzymes, when investigated on a liquid pectin medium. The appearance of unexpected blue color in the pectin medium for some species was discussed, but further investigation is required to elucidate
