Fig. 1From: Characterization, optimization and kinetics study of acetaminophen degradation by Bacillus drentensis strain S1 and waste water degradation analysisBiodegradation of APAP by bacterial strain S1 using batch culture study and morphology of the colony observed after 48 h on plate containing mineral salt medium (MSM) containing APAP. a The strain S1 inoculated with BHM and supplemented with 5 mg/mL of APAP; b after 48 h of incubation of the culture the appearance of the medium changes from colorless to light brown; c similarly after 5 days of incubation the color changed from light brown to black; d morphology of the colony observed after 48 h on plate containing mineral salt medium (MSM) containing APAP, e pilot-scale anaerobic reactor used for biodegradation of APAPBack to article page
