| 摘要 |
A method of producing algal cell wall degrading enzyme by cultivating a thermophilic, bacterial strain of an atypical Bacillus stearothermophilus e.g., W36-7-4 (NRRL B-18394) which produces the alginate lyase in a cultivation medium containing sodium alginate and tryptone, then allowing growth to take place to accumulate alginate lyase, and then recovering the enzyme from the fermentation broth. The novel alginate lyase of this invention is useful as a treatment agent for water cooling systems.
