Kinetics of the biodegradation of monoaromatics by pseudomonas aeruginosa

Water contamination by monoaromatic compounds has risen throughout time, which leads to the necessity of developing new water treatment technology, capable of minimizing their negative effect on the environment. In this context, biological processes present themselves as a solution to the processes...
