Staphylococcus Arlettae, the bacteria that promises to revolutionize the treatment of effluents from the textile industry

As part of an international partnership between Portugal and Brazil, a group of researchers which includes Andrea Zille, a researcher at the Institute of Molecular and Cell Biology of Porto (IBMC) and Artur Cavaco Paulo Department of Textile Engineering University of Minho, published a study on a bacterium which makes it possible to fade and to reduce the toxicity of the effluents of textile industry.

The researchers demonstrated the ability of the bacterium Staphylococcus arlettae to discolor effectively in the absence of oxygen four types of common dye in the textile sector. The samples were subjected to treatment after by aeration to promote oxidation and degradation of hazardous compounds resulting from the degradation of dyes. The study revealed a marked reduction of the toxicity and the concentration of hazardous substances from the water effluent.

The discovery could change the way the textile industry treats its effluent and facilitate the implementation of new directives.
