<p>A thermophilic cellulose-decomposing bacterium clostridium thermocellum biovar.SK522 (FERM BP-3459) which can solubilize lignin, has the optimum growth temperature of 65 to 72 °C, grows in the temperature range from 40 to 80 °C, and ferments cellulose energetically; Thermus acquaticus biovar.SK542 (FERM BP-3382) which is strictly aerobic, has the optimum growth temperature of 72 to 76 °C, grows in a medium of an ordinary concentration in the temperature range from 40 to 82 °C, and produces a thermophilic protease having the optimum working temperature of 75 to 85 °C and the working hydrogen ion concentration (pH) of as wide as 4.0 to 11.3 and a yellow carotenoid pigment; and a mixed culture of the above strains. This culture is useful for treating organic materials containing lignin and/or cellulose for various purposes and for soil conditioning.</p> |
