In our experiments we tested 11 kinds of different lignocellulose materials by means of the method in vitro according to Mellenberger et al. (1970) for a determination of their digestiblity. In experiments carried out with beech sawdust treated with 0.1 M of sulphuric acid a digestibility of 3.7% was found, in sawdust treated with 0.47 M of nitric acid a digestibility of 61.6% was found and after a neutralization with ammonia it amounted to 72.2%. Wood fibre (WF-1) treated enzymatically showed a digestibility of 28.6% and in the WF-2 complemented with newsprint paper it amounted to 33.4%. Untreated beech waste -- forest billets -- showed a low digestibility (5.6%) and that of zero fibre was somewhat higher (12.6%). Difibered beech sawdust showed a digestibility of 44.0% and the digestibility of the biomass prepared from lye waste obtained during the production of cellulose fibres amounted to 74.1%. Waste fibre also showed a high digestibility of 76.0%. Straw enriched with yeast proteins (SL-1) showed a digestibility of 58.0%. Cellulose used as a standard in the course of the testing of lignocellulose materials showed the highest digestibility -- 82.3%.
在我们的实验中,我们根据Mellenberger等人(1970年)的体外方法,测试了11种不同的木质纤维素材料,以确定它们的消化率。在用0.1M硫酸处理的山毛榉锯末进行的实验中,发现消化率为3.7%;在用0.47M硝酸处理的锯末中,消化率为61.6%,用氨中和后达到72.2%。酶处理的木纤维(WF-1)消化率为28.6%,在补充了新闻纸的WF-2中消化率为33.4%。未处理的山毛榉废料——森林短材——消化率较低(5.6%),零纤维的消化率略高(12.6%)。去纤维化的山毛榉锯末消化率为44.0%,由纤维素纤维生产过程中产生的碱液废料制备的生物质消化率为74.1%。废纤维的消化率也很高,为76.0%。在木质纤维素材料测试过程中用作标准的纤维素消化率最高——82.3%。
