Growth analysis of bacteria when subjected to ammonium salts ammonium persulphate, ammonium sulfate, ammonium ferrous sulfate as nitrogen sources by measuring optical density

Growth analysis of bacteria when subjected to Ammonium salts (Ammonium Persulfate, Ammonium Sulfate, Ammonium Ferrous Sulfate) as a nitrogen source by measuring optical density In Luria Bertani Broth (LB) of pH 7.0 effect of nitrogen source on bacterial growth was monitored for two days by adding with 1.5% of Ammonium Persulphate, Ammonium Sulfate, Ammonium Ferrous Sulfate salts separately and inoculated with E.coli, Bacillus, and Pseudomonas. 3 groups with 120 samples per group was analyzed by keeping the threshold 0.05 and G power 80%. coincidence interval 95% and enrollment ratio is 1. Comparing various nitrogen sources on bacterial growth at different times, Ammonium ferrous sulfate elevates the growth up to 22 fold in Bacillus, however for Ammonium Sulfate it ranges between 11 - 12 fold. On the contrary Ammonium persulfate can only increase the growth up to 8 fold. Bacterial growth was found affected upon the addition of nitrogenous sources externally (p
