RESUMO
Dada la creciente importancia que van adquiriendo especies de plantas del género Eucalyptus en la explotación forestal argentina y al considerar los benefícios de la asociación micorrítica, se realizó este trabajo que consistió en desarrollar, en cultivos puros, la simbiosis entre especies de plantas forestales del género Eucaliptus con hongos micorríticos de los géneros Boletus sp2 con Eucalyptus viminalis y entre Boletus sp. y Scleroderma sp. (f) con Eucalyptus rostrata. Los análisis estadísticos confirmaron el efecto beneficioso de las asociaciones desarrolladas para el parámetro peso seco de parte aérea. Estos resultados deberían ser confirmados con ensayos de vivero, con el fin de tener evidencias sobre la respuesta de estas asociaciones en el medio ecológico natural

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.
