Studio comparativo dell'accumulo microbiologico in due demosponge mediterranee

The microbiological accumulation capability in the demosponges Spongia (Spongia) officinalis and Oceanapia isodictyiformis of six microbiological parameters were studied in the water and in sponge samples coming from Porto Cesareo (Northern Ionian Sea). The densities of culturable heterotrophic bacteria, vibrios, total culturable bacteria at 37° C, total and fecal coliforms as well as fecal streptococci were higher in both sponges compared with the corresponding seawater. O. isodictyiformis shows a higher microbiological accumulation capability than S. (S.) officinalis.
