This study was carried out to investigate the antimicrobial activities of bacterial\nisolates of maize against plant pathogens as well as their growth responses\nto some environmental parameters. Twenty four bacterial isolates were obtained\nfrom maize plants collected from the Department of Biological Sciences,\nAfeBabalola University, Ado-Ekiti. The isolates were characterized by\ntheir biochemical and physiological characteristics and were identified as\nKurthiazopfu, Morganellamorganic , Rhodococcusequi , Bacillus subtilis ,\nCatabaterhongkongensis , Brevibacteriumotitidis , Lactobacillus coleohominis ,\nStaphylococcus aureus , Propionibacterium acnes among others. Their responses\nto different NaCl concentrations, sugars, temperature as well as antibiotics\nwere determined. Most of the isolates were able to withstand various\nenvironmental parameters in which they were subjected to. Also, eight isolates\nwere able to ferment sucrose. The bacterial isolates showed a degree of\nresistance to the antibiotics tested. There was a high prevalence of multidrug\nresistant bacteria showing resistance to 3 - 8 drugs. The antagonistic effect of\nthe bacterial isolates against selected fungi was determined. None of the isolates\nshowed antagonistic potential against the fungal pathogens. However,\nthe supposed antagonistic bacterial species can be genetically modified to\nproduce secondary metabolites that will result in biocontrol.
