Abstract
Endophytic bacteria seem to be distributed in most plant species and have attracted increasing attention as they are efficient producers of antimicrobial agents and benefits plant in the biocontrol process against pathogens that are inhibiting plant growth by causing various diseases. In present study, antimicrobial activity was checked of the endophytes isolated from the Eucalyptus alba and Ziziphus nummularia. Antimicrobial activity included antifungal activity against Fusarium oxysporum, Rhizoctonia solani and Sclerotium rolfsii and antibacterial activity against Agrobacterium tumefaciens, Burkholderia gladioli and Erwinia amylovora. Result of the present work showed that the endophytes do inhibit the growth of the pathogenic fungi and pathogenic bacteria and so to some extent contribute in the biocontrol process of the plants against the pathogens. Endophytes existing in plants have a wide range of antimicrobial strains, which are the important potential sources of antimicrobial substances. So it can be suggested from the result that the bacterial endophytes of E. alba and Z. nummularia could be a potential source for antimicrobial substances for biotechnological application.
