For the purpose of utilizing the cellulose digestion on an industrial scale, decomposition products of various kinds of woods and the effect of lignin on the fermentation were investigated. In spite of powerful attack to cellulose or pentosan, cellulose thermophile could not digest lignin isolated chemically by which the fermentation was not effected.
The main interest from the industrial aspect had been in the obtaining of alcohol. Delignificated woods were fermented up to 97% producing 25_??_34% organic acid, although ballmilled woods and ground pulp were not decomposed. But the production of alcohol and recovery of carbon were too poor to be applied on an industrial scale.
In nature, cellulose thermophile could not attack the tissue decayed by fungi or the ballmilled tissue, so it was considered that cellulose bacteria had no such enzymic action on woods as was shown by wood-destroying fungi.
