By means of repeated inoculation method we obtained enrichment cultures of constant cellulose-fermenting power which have always two different types of organisms. And then the symbiotic physiological characters of these organisms were studied about following respects : (1) numerical ratio of vegetable cells in the enrichment cultures of constant cellulose-fermenting power, (2) quantitative limit of inoculum, (3) mode of growth on some nutrient medium, (4) effects of temperature, pH, ultra-violet ray, Rontgen ray.Thus we have succeeded in separating both types of bacteria each other by the symbiotic culture method with yeasts or by the filtration process.The chief thermophilic cellulose-decomposing bacteria can digest cellulose by the cooperation of an other bacterium symbiotically and the latter can be replaced other microorganisms such as yeasts.
