Abstract

The unicellular red alga Porphyridium sp. was grown at various nitrate concentrations. Nitrate affected the maximal cell number and protein content of the cell culture. Within a certain range of nitrate concentrations, depletion of nitrate from the medium caused an increase in the production of cell-wall polysaccharide and starch on a volumetric basis. This result suggests a possible strategy for maximum production of cell-wall polysaccharide. The fraction of polysaccharide bound to the cell wall and the fraction that dissolved in the medium differed in their accumulation pattern.
