Biodegradation of semiconductor volatile organic compounds by four novel bacterial strains: a kinetic analysis.
This study isolated pure microorganisms for further bioreactor applications. Four novel strains of Pseudomonas citronellolis YAIP521, Paracoccus versutus HSAC51, Burkholderia sp. HUEL671, and Pseudomonas aeruginosa JUPG561 were isolated and tested for biodegradation of isopropyl alcohol (IPA), acetone, ethyl lactate (EL), and propylene glycol mono methyl ether acetate (PGMEA), respectively. The maximum biodegradation rates for IPA, acetone, EL, and PGMEA were 5.27, 3.87, 26.86, and 48.93 mg L(-1) h(-1), respectively. The Haldane kinetic parameters determined for these strains when degrading targeted volatile organic compounds were maximum specific growth rate, half-saturation constant, and inhibition constant. The isolated strains have potential application in various bioreactors. The kinetic parameters obtained in this study provide a basis for further bioreactor experiments.
