Influence of Solid Surface, Adhesive Ability, and Inoculum Size on Bacterial Colonization in Microcosm Studies

摘要

Microcosm studies were performed to evaluate the effect of solid surfaces, bacterial adhesive ability, and inoculum size on colonization success and persistence of P. fluorescens or X. maltophilia, each with a Tn5 insertion that conferred resistance to kanamycin and streptomycin. In lake water enrichment microcosms, the presence of beads appeared to influence the abilities of P. fluorescens or X. maltophilia to colonize, as numbers of both organisms were greater in microcosms with beads (significant at same sampling dates at P
