A sarcosine oxidase (SOX)-producing Athrobacter 42-1 was isolated from a chemostat enrichment of 42 ℃. The results showed that SOX from strain 42-1 was an induced enzyme and could be induced by reagents, such as sarcosine, creatine, creatinine and choline chloride. When aeration was suitably reduced...
