The combination treatment of irradiation and heating accelerated the rale of the enzymatic hydrolysis owing to the increase of accesibility of cellulose to enzyme, resulting from the degradation of the tissue of chaff. The degradation of the tissue was accelerated by heating at temperatures above 100 °C after irradiation. Die Wirkung von Warine- und Strahlungsbehandlung auf die enzymatische Hydrolyse bei Hacksel wurde untersucht. Die Kombination von Strahlungs- und Warmebehandlung beschleunigte die enzymatische Hydrolyse infolge des erleichterten Zngangs der Zellulose zum Enzym, der sich aus der Degradation des Hackselgewebes ergab. Die Degradation des Gewebes wurde durch Erhitzung auf Temperaturen uber 100°C nach der Bestrahlung beschleunigt.","PeriodicalId":280283,"journal":{"name":"November 1984","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1984-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116391199","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}
