The fungus also efficiently hydrolysed filter paper cellulose. Comparison of various untreated and alkali-treated cellulosic and lignocellulosic materials as substrates for cellulase production by <em>S. thermophile</em> revealed the most easily degraded substrate was sugarcane bagasse at 2% concentration. This substrate when alkali treated was the most susceptible to enzymic hydrolysis by culture filtrates of <em>S. thermophile</em> grown on untreated bagasse. Optimum hydrolysis was obtained after 18 h incubation with the filtrate at pH 3·5–4 and 45°C. Alkali treatment of bagasse reduced its lignin content significantly and the culture filtrate of <em>S. thermophile</em> grown on untreated bagasse was found to contain xylanase and polygalacturonase in addition to cellulase and cellobiase.</p></div>","PeriodicalId":13629,"journal":{"name":"International Biodeterioration","volume":"27 1","pages":"Pages 75-86"},"PeriodicalIF":0.0,"publicationDate":"1991-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0265-3036(91)90025-M","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85710949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
