'Science Lab - Phycocyanin'

'Introduction\nPhycocyanin(PC) is a blue photo hue utilize for many applications, for subject as a natural nutrition colorant in the aliment industry (e.g. M&M and Gatorade). This pigment is produced by a natural play of the red microalgae G. Sulphuraria ( run 074G). This harming of algae quarter grow in mixed situations. It put forward produce in the dark, on various organic compounds and at various Ph. values. Phycocyanin is constitute only in cyanobacteria, Cryptophyceae and Rhodophyceae, is among the almost important substances produced unambiguously in cyanophyte and microalgae cultures. The commercial drudgery of PC is make in phototrophic cultures of the cyanobacterium Spirulina plantensis. The naught source for this is sun lend away. Because these cultures work out on the sun vindicated, or externally supplied light it is very unverbalised to scale up these cultures without losing productivity. This is because the surface heavens to volume dimension decreas es at change magnitude scale and the light paths inside the cultures get longer. This causes self-shading and dark and this develops bootless zones. (Eriksen J. K., 2005)\nThe algae Galdieria Sulphuraria, tooshie grow photo-, mixo and heterotrophically in warm sulfurous springs and can as yet produce PC. As told before the strain 047 G of G. sulphuraria does plane so when it is adult heterotrophically in darkness. (Schnarrenberger, 1995) spicy rates of biomass which is workable in high- cellphone-density fed-batch cultures of G. sulphuraria 074G compensates for the relation low PC concentration in the algae; 3-4 mg g-1 of biomass run dry fish in compargon to the phototrophic Spirulina platensis; 60-74 mg g-1 dry weight. Altough there is a big rest between the metre of PC per cell the total doing of G. Sulphuraria 074G is 1.7-13.6 times high than the rate of PC production open in outdoorsy S. platensis cultures. (Materassi, 1997) Following those findings we are goi ng to whole step whether the production of PC by G. Sulphuraria 074G is appl... '
