Abstract
Seasonal variation in bacterial numbers and biomass, ATP concentration, heat production, bacterial production and basic sediment chemistry was followed in shallow marine sediments off the Forsmark Nuclear Power Plant on the Swedish Baltic coast. Production and specific growth rate of bacteria were strongly temperature dependent although the sedimentation of diatoms in the spring caused a significant increase in microbial activity in spite of a low temperature. In situ bacterial doubling time and ATP-turnover values indicated that a large portion of the sediment bacteria was “dormant” or non-growing at all seasons, even in summer. Average growth yield of the bacterial community, calculated from the bacterial production and heat production measurements, varied between 17 and 40 % .
