antagonistic interactions between heterotrophic bacteria as a potential regulator of community structure of hypersaline microbial mats.microbial mats are laminae of self-sustaining microbial communities with a high level of competition for resources. we tested the hypothesis that chemically mediated antagonism is a potential mechanism for structuring the bacterial community. in the co-culturing assay, 57% of the isolates expressed antagonistic behavior toward one or more isolates and 5% of the isolates inhibited more than 80% of the isolates. we observed greater levels of antagonism between isolates from adjacent laminae than w ...201322809069
