A bacterial strain was isolated from pond water in Zarqa, Jordan. It has been identified as Comamonas acidovorans NB-9. It showed an antifungal activity against filamentous fungi (Aspergillus niger SQ 40, Fusarium oxysporium SQ 11, Verticillium dahliae SQ 42), yeasts (Saccharomyces cerevisiae SQ 46, Candida albicans SQ 47). All tested gram-positive bacteria (Bacillus megaterium SQ 5, Bacillus cereus SQ 6, Staphylococcus aureus SQ 9, Streptococcus pyogenes SQ 10) and gram-negative bacteria (Escherichia coli SQ 22, Klebsiella spp SQ 33, Pseudomonas mallei SQ 34) were found to be resistant. Comamonas acidovorans NB-9 was found to accumulate the main portion of the antimicrobial substances in their cells. In batch culture, the active antimicrobial substances were produced at the late phase of its growth cycle, reaching their maximal activity at 48 h of growth.The data indicated the possibility of using Comamonas acidovorans NB-9 as a source of antimicrobial substances or as a biocontrol agent of some plant diseases.
