Estudio microbiológico de las aguas del Puerto Pesquero de Mar del Plata / [Fishing seawater microbiology of the Mar de Plata]

RESUMEN

This work deals with different groups of microorganisms in the polluted water of the fishery section of Mar del Plata harbour and in the way followed by the fisher’s boats. Bacteriological determinations were: total count, MPN of coliforms, proteolitic and anaerobic bacteria. These groups were selected because of their activity in fish spoilage and/or infection. The microbial groups were studied as follows: direct plate count for total number, most probable number (MPN) for coliforms and fecal type strains according with Mc Crady tables; proteolitic and anaerobic bacteria were cualitatively tested, cuantitative determinations are given in two tables. Obtained results show a heavy water pollution that rapidly decreases towards the harbour entrance.
