ABSTRACT: An experiment was carried out for identification and determination of malathion
degrading phosphate solubilizing bacteria isolated from the agricultural
fields. In this study, malathion degrading phosphate solubilizing bacteria
were identified using NBRIP (National Botanical Research Institute’s phosphate
growth medium) media. A number of bacterial colonies were screened
from agricultural fields. From primarily screened colonies 4 isolates were
identified as phosphate solubilizing bacteria through qualitative and quantitative
analysis. The isolated 4 bacterial colonies were inoculated in NBRIP
broth media enriched with malathion pesticides to observe degradation of
malathion pesticide under incubation study at three different temperatures
(25°C, 30°C and 37°C). However, all the four isolates showed capability in
degrading malathion pesticide. The study clearly revealed that phosphate solubilizing
bacteria can be used in bioremediation of environmental pollution
caused by malathion pesticide.
