Bacterial carbon flux through microbial loop in the middle Adriatic sea

Evaluation of bacterial carbon flux through microbial loop was elaborated in coastal area, where the protozoan grazing experiments were run using the size fractioning technique. Production of bacteria and HNF suggests that these organisms fix a significant amount of organic carbon. Small HNF were the most important bacterial grazers. About 20% of annual bacterial production was chanelled through the microbial loop. However, bacterial carbon flux through the microbial loop showed marked seasonal oscillations with considerably higher values recorded during the warmer part of the year. Thus, in that period the microbial loop could be an important link between primary production and higher trophic levels.
