Biodegradation of phenol by pseudomonas aeruginosa, acinetobacter sp. and stenotrophomonas maltophilia isolated of the sludge activated of a steel industry
The purpose of this work was to study the degradation capacity of phenol by strains of Pseudomonas aeruginosa, Acinetobacter sp. and Stenotrophomonas maltophilia isolated from activated sludge from a steel industry. For this, a study of the kinetics of microbial growth and degradation of phenol, besides a factorial planning was carried out, varying the initial concentration of phenol and the pH. Pseudomonas aeruginosa removed 100% of the phenol in 72 h, when the initial concentration of the compound was 250 mg L-1 and the pH was controlled at 6.4. The bacterium Acinetobacter sp.
