Última Selection of thermophilic and thermotolerant fungi for the production of cellulases and xylanases under solid-state fermentation BJM Moretti,Marcia M. S.; Bocchini-Martins,Daniela A.; Silva,Roberto Da; Rodrigues,André; Sette,Lara D.; Gomes,Eleni. Twenty-seven thermophilic and thermotolerant fungal strains were isolated from soil, decaying organic matter and sugarcane piles based on their ability to grow at 45ºC on medium containing corn straw and cardboard as carbon sources. These fungi were identified in the genera Aspergillus, Thermomyces, Myceliophthora, Thermomucor and Candida. The majority of the isolated strains produced xylanase and cellulases under solid state fermentation (SSF). The highest cellulase and xylanase productions were obtained by the cultivation of the strains identified as Aspergillus fumigatus M.7.1 and Myceliophthora thermophila M.7.7. The enzymes from these strains exhibited maximum activity at pH 5.0 and at 60 and 70ºC. The endo-glucanase from A. fumigatus was stable from...

A thermophilic fungal strain producing both pectinase and polygalacturonase was isolated after primary screening of 120 different isolates. The fungus was identified as Aspergillus fumigatus Fres. MTCC 4163. Using solid-state cultivation, the optimum levels of variables for pectinase and polygalacturonase (PG) production were determined. Maximal levels of enzyme activities were achieved upon growing the culture in a medium containing wheat bran, sucrose, yeast extract and (NH4)2SO4 after 2-3 days of incubation at a temperature of 50ºC. Highest enzyme activities of 1116 Ug-1 for pectinase and 1270 Ug-1 for polygalacturonase were obtained at pH 4.0 and 5.0, respectively.
