Effect of nutritional factors on the culture of Nostoc sp. as a source of phycobiliproteins

The effect of nutritional factors in a new culture medium (BW3) is described for the cyanobacterium Nostoc sp. The growth of Nostoc sp. was higher in BW3 than in control media currently used for cyanobacteria. With medium BW3 the content of the pigment c-phycocyanin depended on the culture condition...
