Abstract

See full text

A process for treatment of hydrocarbon refinery wastewater producing a low bio-sludge, the process including utilizing microbial consortia comprising at least one species of Pseudomonas and at least one species of Bacillus in a ratio of 10:1 to 1:10. The species of Pseudomonas and species of Bacillus have constitutive expression of at least one hydrocarbon degrading gene. The species of Pseudomonas are selected from the group consisting of Pseudomonas stutzeri (MTCC 25027), Pseudomonas aeruginosa (MTCC 5389), Pseudomonas aeruginosa strain IOC DHT (MTCC, 5385), Pseudomonas putida IOCR1 (MTCC 5387), Pseudomonas putida IOC5a1 (MTCC 5388) and a mutant thereof. The species of Bacillus are selected from the group consisting of Bacillus 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. The microbial consortia is used in concentration of at least 102 cfu/ml.
