Growth of, and rate of acid production by, six cultures of lactic acid bacteria were increased in the presence of Micrococcus isolate F4 or a preparation of its capsular material. Concentrations of hydrogen peroxide found in pure cultures of the lactic acid bacteria were not detectable, or were greatly reduced, in mixed culture with Micrococcus isolate F4. The capsular material was not as effective as whole cells in preventing accumulation of H(2)O(2). Catalase stimulated growth of, and the rate of acid production by, the lactic acid bacteria, but not to the same extent as Micrococcus isolate F4 in some cultures. The existence of two mechanisms for micrococcal stimulation of the lactic acid bacteria is postulated. One mechanism involves removal of H(2)O(2); the other has not been characterized.
在微球菌分离株F4或其荚膜物质制剂存在的情况下，六种乳酸菌培养物的生长和产酸速率增加。在与微球菌分离株F4混合培养时，乳酸菌纯培养物中发现的过氧化氢浓度无法检测到或大大降低。荚膜物质在防止H₂O₂积累方面不如完整细胞有效。过氧化氢酶刺激了乳酸菌的生长和产酸速率，但在某些培养物中刺激程度不如微球菌分离株F4。推测存在两种微球菌刺激乳酸菌的机制。一种机制涉及去除H₂O₂；另一种机制尚未明确。
