Both of the thermophiles were motile by means of lophotrichous flagella and had high growth rate on medium containing cellulose. Optimal growth occured at 60℃ for the two thermophiles and at PH 7. 5 for Y, PH 7. 37. 5 for W strain. Y strain produced yellow pigment in cellulose medium and had yellow-colored, round or watery colonies in cellulose agar. The colonies of W strain were white -colored and similar in form to that of Y strain. The mesophile, Clostridium sp. B, was motile with peritrichous flagella. The colonies grown on cellulose agar were white and round with slightly undulate margins. The optimal growth temperature and PH of B strain were 40℃ and 7. 0-7. 2, respectively. All of the three Clostridia fermented varieties of carbohydrates and in cellulose media produced the similar end-products: CO〓H〓, ethanol and acetic acid. The DNA compositions were 34 mol% for Y and B, 35 mol% for W strain.
