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 this phenomenon.

Rio Tinto as a niche for acidophilus enzymes of industrial relevance

“…Talaromyces was described as a sexually reproducing Penicillium species (Benjamin, 1955), although several authors have reviewed this classification, including Penicillium subgenus Biverticillium and Talaromyces in a monophyletic clade distinct from the other Penicillium sub-genera (Houbraken et al, 2020;Yilmaz et al, 2014). In species belonging to Chaetomium, Neosartorya, Mucor, Byssochlamys and Nectria cellulases have also been reported (Elsababty, 2015;Moo-Young et al, 1977;Morais et al, 2018;Pardo & Forchiassin, 1999;Xue et al, 2016); however, there is not much information about cellulases from the Acidiella species, and our results suggest that these strains may be unexplored micro-organisms for industrial exploitation.…”
