Abstract
The turnover times of glucose, averaged for 0–10 m in the upper waters of Lake Kinneret and measured by the addition of single or multiple concentrations of substrate, ranged from 23 to 188 hours and 1 to 87 hours respectively. Potential uptake rates (estimated as Vmax) ranged from 0.095 to 1.94 µg glucose l−1h−1, while measured uptake rates varied from 0.09 to 1.1 µg glucose l−1h−1. Concentrations of dissolved carbohydrates and glucose averaged 0.71 mg glucose equivalents l−1 and 39 µg glucose l−1 respectively. No evident relationships between glucose cycling and any fractions of dissolved organic matter, phytoplankton biomass or primary productivity were found. Turnover times were generally most rapid immediately after the decline of the spring Peridinium bloom. The respiration percentage of incorporated glucose ranged from 25% to 61% with highest values during the summer months. Respiration may be influenced by the nature of the indigenous bacterial population as well as by temperature. Daily heterotrophic glucose carbon uptake was about 9% of the photosynthetic incorporation and could provide a bacterial yield of about 7 × 104 ml−1d−1.
