Summary:A process for treatment of hydrocarbon refinery wastewater producing a low bio-sludge and said process comprises utilizing microbial consortia comprising at least one species ofPseudomonasand at least one species ofBacillusin a ratio of 10:1 to 1:10, wherein species ofPseudomonasand species ofBacillushave constitutive expression of at least one hydrocarbon degrading gene, wherein the species ofPseudomonasare selected from the group consisting ofPseudomonas stutzeri(MTCC 25027),Pseudomonas aeruginosa(MTCC 5389),Pseudomonas aeruginosastrain IOC DHT (MTCC, 5385),Pseudomonas putidaIOCRI (MTCC 5387),Pseudomonas putidaIOC5al (MTCC 5388) and a mutant thereof, wherein the species ofBacillusare selected from the group consisting ofBacillus subtilis(MTCC 25026),Bacillus substilis(MTCC 5386),Bacillus thermoleovorans(MTCC 25023),Bacillus stearothermophilus(MTCC 25030),Lysinibacillus sp.(MTCC 25029),Lysinibacillus sp.(MTCC 5666) and a mutant thereof, and wherein the microbial consortia is used in concentration of at least 102cfu/ml.
