COMPARISON OF GROWTH OF PHOTOSYNTHETIC BACTERIA IN AXENIC CULTURES AND IN Co-CULTURES

摘要: 采用光合细菌不同菌株、光合细菌株与异养细菌株间混合培养,比较它们与单株培养物生长量的差异。试验结果表明,不同组合的混合培养物其生长量均不同程度高于单株培养物。光合细菌株间混合培养物生长量约高于对照036—17.4%;多数增长11%以上。光合细菌株与异养细菌株间混合培养效果更为显著,增长量为单种培养的1.34—5.6倍。初步试验表明混合培养菌株间有互利或偏利关系。

Abstract: The growth of photosynthetic bacteria (PSB) in axenic and co-ultures was studied. The abundance of PSB co-cultured with PSB strains or with heterotrophic bacteria strains was higher than that in axenic culture. The study of the interaction between PSB and heterotrophic bacteria strains revealed the relationship of synergism and /or commensalism.
