Abstract
Nutrient and population dynamics accompanying algae-bacteria interaction were observed in unialgal, 18-liter batch cultures during a light-dark cycle. The green alga Chlorella vulgaris, and the nitrogen fixing blue-green Anabaena flos-aquae were inoculated with an aquatic community of bacteria. The bacteria community enhanced the regeneration of nutrients. Of special note, is the observed generation of soluble nitrogen in the synthetic growth media via nitrogen fixation followed by mineralization.
