Reduction of nitrate and production of ammonia, nitrite, and nitrate by Serratia marcescens OK482790 strain. Where A- Deep red colour with sulfanilic acid and alpha-naphthylamine mixture (1:1) indicated nitrite production. B- Golden yellow colour with Nessler’s reagent indicated ammonia production. C- Deep blue colour with Trommsdorf,s reagent indicated nitrite production. D- Deep blue colour with Diphenyl amine reagent indicated nitrate production
