Cultural environments for the thermophilic cellulose fermentation were examined as a preli-minary experiment for isolation of cellulose decomposer. Various techniques, for example, the enrichment method, the dilution or heating method, the cellulose agar plating and the application of bacteriostatic agents, etc., were used in order to get a pure culture, but some contaminants were always found. Generally, the reproduction time of thermophile was so rapid that it was practically impossible to obtain a perfect result, in spite of the excellent Snieszkos method. Cellulose fermentation proceeded under reduced condition, and yet addition of a reducing agent or strictly anaerobic incubation spoiled the fermentation. A contaminant, isolated as a, pure culture, was very similar to Bac. thermofibrineolus which was reported to be cellulose fermenter without confirmation, so it was doubtful that Bac. thermofibrincolus was a cellulose-decomposing bacterium.
