A bacterium Pseudomonas sp. TRMK1 capable of utilizing various phenylpropanoids was isolated from agro-industrial waste by enrichment culture technique. It is gram-negative, motile, aerobic, and able to utilize three different phenolic acids such as p-coumaric, ferulic, and caffeic acids at concentrations of 5, 10, and 15 mM in 18 h of incubation. The residual concentration of phenolic acids was analyzed by HPLC. The catabolic pathway of p-coumaric, ferulic, and caffeic acids is suggested based on the characterization of metabolic intermediates by GC, GC-HRMS, and different enzymatic assays. Further, Pseudomonas sp. TRMK1 utilizes a wide range of mixture of phenolic acids present in the synthetic effluent.
