Mineralization of metanilic acid by Pseudomonas aeruginosa CLRI BL22

Pseudomonas aeruginosa CLRI BL22 was able to degrade metanilic acid, a sulfonated aromatic amine upto a concentration of 1,500 mg l-¹. The degradation of metanilic acid started when the organism reached its exponential growth phase. Chromatographic and spectrophotometric analyses confirmed the prese...

Zusammenfassung:	Pseudomonas aeruginosa CLRI BL22 was able to degrade metanilic acid, a sulfonated aromatic amine upto a concentration of 1,500 mg l-¹. The degradation of metanilic acid started when the organism reached its exponential growth phase. Chromatographic and spectrophotometric analyses confirmed the presence of aniline and β-keto adipic acid indicating the ortho pathway reaction. Further proof for this pathway was provided by dioxygenase activity of the strain grown in the medium containing metanilic acid and glucose.
