Biochemical characterization of effective PGPRs from rhizosphere of banana against tip over disease caused by Erwinia carotovora subsp. carotovora

Abstract

In recent years, there has been a reverse interest in the search of plant growth promoting rhizobacterias (PGPRs) for sustainable crop production. Banana is an economically important tropical fruit crop, which is subjected to infection by fungai, bacteria, virus and nematodes. A total of 64 Bacillus spp. were isolated from rhizosphere of banana. Among 64 isolates 12 isolates were found to be effective against the Erwinia carotovora subsp. carotovora in vitro. Among them most effective isolates were further subjected for biochemical characterization. The biochemical studies confirmed them to be as Bacillus pumilis, Bacillus subtilis and Bacillus cereus.
