Abstract

Rhizospheric bacteria are known to influence plant growth by direct and indirect mechanisms. A total of 220 phosphate solubilizing bacteria were isolated from different rhizosphere soil in Northern part of Thailand. These isolates were screened for their plant growth promoting factors like production of ammonia, siderophore and cell wall degrading enzyme activities; cellulase, chitinase and proteolytic enzyme. More than 64% of the isolates produced ammonia and 23% produced siderophore on chrome azurole S agar plates. Moreover, test isolates produced cell wall degrading enzyme; cellulose (6%), chitinase (6%) and proteolytic enzyme (5%) on agar plate
method. The results show that rhizospheric phosphate utilizing bacteria could be a promising source for plant growth promoting agent in agriculture.
