Effect of dual substrates on aniline mineralization by Pseudomonas testosteroni 6F1 = Pseudomonas testosteroni 6F1의 아닐린 분해에 미치는 이차기질의 영향

Abstract

The simultaneons mineralization of aniline and other secondary carbon sources by Pseudomonas testosteroni 6Fl were evaluated by the lag time and the enzyme induction level. The lag time for aniline mineralization by P. testosteroni 6Fl was 7 hours, whereas the lag time for aniline and readily utilizable secondary substrates were 1-3 hours. This stimulated degradation resulted from the simultaneous use of secondary substrates and aniline, the increased rate of enzyme induction, and the in-creased rate of the cell growth. The enzyme induction level of P. testosteron 6F1 were varied according to the kinds of secondary substrate.
