EFFECT OF VARIOUS CARBON SOURCES ON THE GROWTH PROPERTIES AND MORPHOLOGY OF $SPIRULINA~PLATENSIS$

Cyanobacteria generate biomass under photoautotrophic conditions during photosynthesis. Cultivation of cyanobacteria photoheterotrophic using various organic carbon sources can increase yield biomass. In the current study, effect on growth properties and morphology Spirulina platensis, as well production photosynthetic pigments: chlorophyll a, carotenoids, phycocyanin were investigated. Carbon sources, such glucose, fructose succinate, caused not only an in cyanobacterial rate, but also morphological changes S. platensis trichomes. An amounts pigments was observed. Thus, fructose, succinate are more efficient substrates for cultivation these cyanobacteria.
