A few days ago we received the visit of Dr. Nildo da Silva Dias from the Federal Rural University of Semi-Arido-Brazil. He was accompanied by Dr. Nelda Olivera and Dr. Magalí Marcos, both from the IPEEC – CONICET Microbiology and Biotechnology Laboratory. Dr. Silva Dias visited us after giving a postgraduate training in Salinization of irrigated areas, interested in learning about our process of management of industrial fishing effluents and the reuse of the treated liquid for the cultivation of native plants
