Survival and competitive ability of ammonia excreting and nonammonia excreting azotobacter chroococcum strains in sterile soil



Survival and competitive ability of ammonia excreting and nonammonia excreting azotobacter chroococcum strains in sterile soil



Plant & Soil 69(1): 79-84



The survival of 2 multiple antibiotic resistant native isolates of A. chroococcum (A10 and A42), one of them (A10) having high nitrogenase activity and high ammonia excreting ability and another (A42) having low nitrogenase activity and low ammonia excreting ability were studied in sterile sandy loam soil with amendments of compost and glucose and without amendments. The decrease in cell numbers over a period of 4 wk in all 3 types of treatments approximated 4 log units. The death rate was greater in the first 2 wk. In all treatments A10 showed better survival and competitive ability than A42 both singly and in mixed culture.
