Isolation of a xanthobacter sp. degrading dichloromethane
Emanuelsson, Maria A. E.; Osuna, M. Begoña; Jorge, Ruben M. Ferreira; Castro, Paula M. L.A bacterial strain able to degrade dichloromethane (DCM) as the sole carbon source was isolated from a wastewater treatment plant receiving domestic and pharmaceutical effluent. 16S rDNA studies revealed the strain to be a Xanthobacter sp. (strain TM1). The new isolated strain when grown aerobically on DCM showed Luong type growth kinetics, with lmax of 0.094 h-1 and Sm of 1,435 mg l-1. Strain TM1 was able to d...
Treatment of halogenated organic compounds and monitoring of microbial dynamics...
Emanuelsson, Maria A. E.; Osuna, M. Begoña; Sipma, Jan; Castro, Paula M. L.Two up-flow fixed bed reactors (UFBR) were operated for 8 months treating a model synthetic wastewater containing 2-fluorobenzoate (2-FB) and dichloromethane (DCM). The stability of the reactors under dynamic conditions, that is, sequentially alternating pollutants (SAP), shock loads, and starvation periods was assessed. Two support materials were used: expanded clay (EC) that does not adsorb 2-FB or DCM, and g...
