Batch cultivation of Xanthobacter Py2 on 1-pentene: growth yield and cell activity for the degradation of 1,2-epoxyhexane

van Keulen, F., Fonseca, M. M. R. da

Abstract

The propene isolated strain Xanthobacter Py2 was able to grow on 1-pentene. The biomass yield for growth under l-pentene limiting conditions was 0.48 (C_eq/C_eq). Upon storage at both +4ºC and -20ºC no loss of enzymatic epoxide degrading activity in resting cell suspensions was observed after a month. However, activity decay was pronounced during the stationary phase of growth as well as under reaction conditions.
