Thermophilic fibrinolytic bacteria and their use (THERMOPHILIC CELLULOSE-DECOMPOSING BACTERIUM AND UTILIZATION THEREOF)

摘要

Thermophilic fibrolytic bacterium Clostridium thermocelum Biovar SK 522 (LGN), which has a lignin solubilizing ability, has a growth temperature of 65 to 72 ° C, grows in a temperature range of 40 to 80 ° C, and ferments fibrin vigorously. 3459) and absolute aerobic, growth and temperature of 72 to 76 ℃, grown in a medium of normal concentration in the temperature range of 40 to 82 ℃, the functional temperature of 75 to 85 ℃, functional hydrogen ion concentration of pH = 4.0 to 11.3 Provided are Cymus Aquaticus Biovar SK 542 (Remarks Kenjogi No. 3302), which produce protease and carotenoid yellow pigments having high temperature activity, and a mixed culture of these strains. This mixed culture is useful for the treatment and soil improvement of lignin and / or fiber-containing organic materials for various purposes.
