ISOLATION, IDENTIFICATION OF NITRIFYING BACTERIA FROM SHRIMP CULTURE POND SOIL AND EFFECT OF PH AND TEMPERATURE ON THEIR NITRIFYING EFFICIENCY
Balamurali. P, Muralikrishnan.V
Abstract :
Two efficient strains (AOB-6 and NOB-4) of ammonia oxidizing bacteria and nitrite oxidizing bacteria have been isolated in pure culture by liquid enrichment techniques from shrimp culture pond bottom soil. Both were identified as gram negative, rod shaped and similar to the genera Nitrosomonas (AOB-6 KT231978) and Nitrobacter (NOB-4 KT231980) by 16s RNA sequencing. The both strains of AOB-6 and NOB-4 were studied on bioconversion of ammonium to nitrite and nitrite to nitrate at different pH and temperature respectively. The strain AOB-6 has been recorded highest ammonium oxidation to nitrite pH 8 and Temperature 30˚C.
