Abstract
Podamo, J. (1975). Ecometabolism of a shallow marine lagoon at Ostend (Belgium) : 3. The role of planktonic heterotrophic bacteria. 10th Europ. Symp. Mar. Biol. 2: 517-530
In order to assess the importance of the recycling of organic matter into nutrients in the water column, the bacterial biomass was evaluated by the spread-plate counts method, and the heterotrophic activity by two methods : initial consumption rate of oxygen and anaplerotic bicarbonate fixation.
The biomass of aerobic heterotrophic bacteria does not reflect the heterotrophic activity and cannot be used as an index for this activity.
This activity is always important as a recycling process for the phytoplanktonic organic matter it is depending on. Different periods can be recognized, with varying importance (relative to other recycling factors) of bacterial activity.
