摘要

Microbial communities present in the rhizoplane of plants play an essential role in both plant growth and physiological functioning. These microbes are attracted to the volatile compounds released by plants as a by product of their metabolism. Presentinvestigation was designed to isolate and identify microbes from the rhizoplane regions of the tissue culture raised medicinal plant, Decalepis arayapathra KMA 05 clones. Two fungal species, i.e., Cladosporium sp. F42 (FJ755822) and Epicoccum nigrum (KR094452) were isolated from the rhizoplane. In antagonistic activity assay, E. nigrum was found to inhibit the growth of Cladosporium sp., thus displaying its biocontrol potential. The GC-MS analysis of fungal extracts showed bioactive molecules that canact as anti-microbial, anti-cancerous, and plant growth-promoting molecules. Moreover, exclusive and high concentration of PPDHMP from the E. nigrum supports for its involvement in Cladosporium growth inhibition. Thus the identified microbes can be exploited as biocontrol agents and plant growth-promoting microbes for D. arayalpathra.
