Cultivation and ecosystem role of a marine roseobacter clade-affiliated cluster bacterium.

abstract：:The effects of antibiotic production on rhizosphere microbial communities of field-grown Phaseolus vulgaris were assessed by using ribosomal intergenic spacer analysis. Inoculum strains of Rhizobium etli CE3 differing only in trifolitoxin production were used. Trifolitoxin production dramatically reduced the diversity...
