TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preparation (Claimed): The polypeptide is produced by transforming host cell with an expression vector encoding the polypeptide, and culturing the host cell under conditions enabling expression of the polypeptide, and optionally recovering and purifying the polypeptide. Preferred Biomolecule: The polypeptide has at least 80%, preferably at least 85%, more preferably at least 90%, even more preferably at least 95%, and most preferably at least 98% identity to SEQ ID NO: 11 or at least 75%, preferably at least 80%, more preferably at least 85%, more preferably at least 90%, even more preferably at least 95%, and most preferably at least 98% identity to SEQ ID NO: 12 or a fragment or variant having ferulic esterase activity. The polypeptide is obtained from Chaetomium thermophilum or Melanocarpus albomyces, preferably C.thermophilum CBS 132416 or M.albomyces CBS 132099. The polynucleotide comprises a gene included in a microorganism (DSM 26070 and DSM 26071). The enzyme preparation further comprises at least one enzyme chosen from cellobiohydrolase, endoglucanase, beta -glucosidase, beta -glucanase, xyloglucanase, xylanase, beta -xylosidase, cellobiose dehydrogenase, mannanase, beta -mannosidase, alpha -glucuronidase, acetyl xylan esterase, alpha -arabinofuranosidase, alpha -galactosidase, pectinase, involving endo- and exo- alpha -L-arabinases, endo- and exo-galactoronase, endopectinlyase, pectate lyase and pectinesterase, phenol esterase, ligninase involving lignin peroxidase, manganese-dependent peroxidase, hydrogen oxygen-generating enzyme, laminarinase, chitosanase, GH61 protein, and laccase with or without mediators. The enzyme preparation further comprises xylanase. Preferred Method: The method involves cleaning the interior of a dishwasher by contacting at least part of the interior of the dishwasher with the polypeptide or an enzyme preparation. The cellulosic or lignocellulosic material is textile material, plants used in animal feed, or wood-derived pulp or secondary fiber. The method involves cleaning the interior of a dishwashing device, and baking for improving the dough and bread characteristics. EXAMPLE - No suitable example given.
