• Dissolved and particulate organic carbon, bacterial biomass, microbial enzymatic activities (leucine aminopeptidase, ß-glucosidase and alkaline phosphatase), bacterial production, respiration rates and bacterial growth efficiency were determined in ten stations of the Ionian Sea (winter 1998-99) with the aim of characterizing the recycling of biogenic carbon and phosphorus in the different water masses, previously identified. All microbial activities decreased markedly with depth, with a sharp increase in the benthic boundary layer, where potential remineralization rates of phosphorus up to 1.03 µg P·dm-3d-1 and bacterial carbon production of 0.078 µg C·dm-3d-1, were recorded. Those rates were close to the surface ones; the bacterial growth efficiency was also around 20%, similar to the surface value, sustained the microbial food chain at bottom. The daily hydrolysis of the organic carbon pool varied from 0.67% (Ionian Surface Water) to 0.02% (Deep Water). Alkaline phosphatase activity was generally low in the intermediate and deep layers, in relation to the higher inorganic P content. The last facts support the hypothesis that deep waters of Ionian Sea, because of their young age, carry a larger amount of labile DOC which reduces the need for a high recycling activity by bacterial community. As a matter of fact, a relatively higher activity per cell in carbon production rates was found in the deep layer where the very recently formed Cretan Sea Outflow Water was present (literal)

Abstract

• Dissolved and particulated organic carbon, bacterial biomass (BB), microbial ectoenzymatic activities (EEA: leucine aminopeptidase, ß-glucosidase and alkaline phosphatase), bacterial production (BP), respiration rates (R) and bacterial growth efficiency (BGE) were determined in 10 station of the Ionian Sea with the aim of characterizing the recycling of biogenic carbon and phosphorus in different water masses. All the microbial activities decreased markedly with depth with a sharp increase in the benthic boundary layer, where potential remineralization rates of P up to 1.03µg P*dm-3d-1 and bacterial carbon production of 0.078µg C*dm-3d-1 were recorded.Those rates were close to the surface ones. The daily hydrolysis of organic carbon by EEA varied from 0.67% (Ionian Surface Water) to 0.02% (Cretan Deep Water). The BGE was also around 20% in BBL similar to the surface values sustaining microbial food chain at bottom. (literal)
