Response of Prochlorococcus ecotypes to co-culture with diverse marine bacteria.

ABSTRACT: Interactions between microorganisms shape microbial ecosystems. Systematic studies of mixed microbes in co-culture have revealed widespread potential for growth inhibition among marine heterotrophic bacteria, but similar synoptic studies have not been done with autotroph/heterotroph pairs, nor have precise descriptions of the temporal evolution of interactions been attempted in a high-throughput system. Here, we describe patterns in the outcome of pair-wise co-cultures between two ecologically distinct, yet closely related, strains of the marine cyanobacterium Prochlorococcus and hundreds of heterotrophic marine bacteria. Co-culture with the collection of heterotrophic strains influenced the growth of Prochlorococcus strain MIT9313 much more than that of strain MED4, reflected both in the
