Heterotrophic bacteria in the northern Adriatic Sea: seasonal changes and ectoenzyme profile

摘要

A seasonal study of the quantitative and qualitative distribution of heterotrophic bacterial community was carried out in the Adriatic Sea between April 1995 and January 1996, in order to evaluate its spatial and temporal variability and metabolic potential in the degradation processes of organic matter. The culturable bacteria (CFU) ranged between 0.1 and 22/100 of total bacterioplankton with A maximum percentage in surface samples of coastal zones. Their distribution was generally Affected by the prevailing hydrological conditions.
