Predator-specific enrichment of actinobacteria from a cosmopolitan freshwater clade in mixed continuous culture

Popis výsledku v původním jazyce

We investigated whether individual populations of freshwater bacteria in mixed experimental communities may exhibit specific responses to the presence of different bacterivorous protists. In two successive experiments, a two-stage continuous cultivationsystem was inoculated,vith nonaxenic batch cultures of the cryptophyte Cryptomonas sp, Algal exudates provided the sole source of organic carbon for growth of the accompanying microflora. The dynamics of several 16S rRNA-defined bacterial populations were followed in the experimental communities. Although the composition and stability of the two microbial communities differed, numerous members of the first assemblage could again be detected during the second experiment. The introduction of a size-selectively feeding mixotrophic nanoflagellate (Ochromonas sp.) always resulted in an immediate bloom of a single phylotype population of members of the class Actinobacteria (Acl). These bacteria were phylogenetically affiliated with an uncultu
