Title
Recombinant expression of Toluene o-Xylene Monooxygenase (ToMO) from Pseudomonas stutzeri OX1 in the marine Antarctic bacterium Pseudoalteromonas haloplanktis TAC125
Abstract

The psychrophilic bacterium Pseudoalteromonas haloplanktis TAC125, isolated from Antarctic seawater, was used as recipient for a biodegradative gene of the mesophilic Pseudomonas stutzeri OX1. tou cluster, coding for Toluene o-Xylene Monooxygenase (ToMO), was successfully cloned and expressed into a “cold expression” vector. Apparent catalytic parameters of the recombinant microorganisms on three different substrates were determined and compared with those exhibited by Escherichia coli recombinant cells expressing ToMO. Production of a catalytically efficient TAC/tou microorganism supports the possibility of developing specific degradative capabilities for the bioremediation of chemically contaminated marine environments and of industrial effluents characterised by low temperatures.
