Abstract

Two Pseudomonas isolates, named ES-1 and ES-2, were shown to possess a wide degradative spectrum for haloalkanes in general and bromoalkanes in particular but did not degrade nonsubstituted alkanes. The utilization of water-insoluble haloalkanes, such as 1-bromooctane, appeared to consist of three phases: (i) extracellular emulsification by a constitutively excreted, broad-spectrum surface-active agent, (ii) dehalogenation by an inducible hydrolytic dehalogenase (possibly periplasmic), and (iii) intracellular degradation of the residual carbon skeleton. Several observations suggest the existence of more than one dehalogenase in strain ES-2.
