Microbial adaptation to bromobenzene in a chemostat

Microorganisms capable of growth with bromobenzene as their sole source of carbon and energy were selected from a continuously growing community of microorganisms initially selected for growth at the expense of benzene as sole source of carbon and energy. These experiments selected two strains of Pseudomonas that used bromobenzene as sole carbon and energy source. After the selection, the strains in either pure or mixed culture were capable of growing at the expense of benzene, bromobenzene, and chlorobenzene, but not iodobenzene.
