Abstract
The uptake of C into primary and major products of photosynthesis in natural populations was determined in 4 and 24 h time-series experiments at 50% of the incident radiation. During active growth the communities assimilated the largest proportion of C into polysaccharides at all time intervals and the amount of label incorporated into primary products was approximately equal to or exceeded that in the proteins and lipids. When there was no growth the synthesis of protein was the dominant metabolic process. The community in experiment 6 appeared to be in an active phase, in 1 experiment the uptake of C into protein was faster than with no growth an during the dark period actively growing cells maintained protein production by using C stored in the polysaccharides only; stationary growth cells required both primary products and polysaccharides for protein synthesis at night.Keywords
