In the present study, the bacterium Achromobacter xylosoxidans was isolated from tannery effluent sludge sample in Dindugal, Tamil Nadu, India and screened for its bio-control efficacy against selected plant pathogens viz., Alternaria solani, Curvularia lunata and Fusarium oxysporum under in vitro. It was observed that maximum percent inhibition of mycelial growth of C. lunata (95%), followed by A. solani (85%) and F. oxysporum (80%). An attempt was also made for testing its plant growth promoting traits such as production of Indole acetic acid (IAA), phosphate solubilization efficacy, Hydrogen cyanide (HCN), ammonia and catalase production. Significant amount of plant growth promoting traits were noticed. Further studies on mechanism of bio-control against plant pathogens and plant growth promoting activities of Achromobacter xylosoxidans need to be conformed under in-vivo condition.
