UV spectrum analysis of Phenazine like compound from P. aeruginosa VSMKU1. A and B are UV spectrum profile in which A reveals the pure phenazine compound showing a high absorbance line was observed at k max at 362 nm while B Phenazine like compound produced by P. aeruginosa VSMKU1 exhibited a high absorbance line at 362 nm and lower absorbance line showing a peak at 347 nm. The peak observed at 362 nm of the crude metabolite from P. aeruginosa VSMKU1 coincides with that of pure phenazine.
