'Science Lab - Phycocyanin'

'Introduction\nPhycocyanin(PC) is a blue photopaint employ for many applications, for interpreter as a natural fodder colorant in the food industry (e.g. M&M and Gatorade). This pigment is produced by a natural summercater of the red microalgae G. Sulphuraria ( bank line 074G). This material body of algae stomach grow in respective(a) situations. It keep produce in the dark, on various organic compounds and at various Ph. values. Phycocyanin is raise only in cyanobacteria, Cryptophyceae and Rhodophyceae, is among the closely important substances produced unequivocally in cyanobacterial and microalgae cultures. The commercial proceeds of PC is do in phototrophic cultures of the cyanobacterium Spirulina plantensis. The muscularity source for this is sun at large(p). Because these cultures matter on the sun clarification, or externally supplied light it is very backbreaking to scale up these cultures without losing productivity. This is because the surface study to vol ume symmetry decreases at increase scale and the light paths inside the cultures formulate longer. This causes self-shading and dark and this develops bootless zones. (Eriksen J. K., 2005)\nThe algae Galdieria Sulphuraria, crapper grow photo-, mixo and heterotrophically in warm sulfurous springs and can calm produce PC. As told before the strain 047 G of G. sulphuraria does notwithstanding so when it is expectant heterotrophically in darkness. (Schnarrenberger, 1995) noble rates of biomass which is practical in high- cellular telephone-density fed-batch cultures of G. sulphuraria 074G compensates for the relational low PC concentration in the algae; 3-4 mg g-1 of biomass run dry system of weights in comparability to the phototrophic Spirulina platensis; 60-74 mg g-1 dry weight. Altough there is a big residual between the summation of PC per cell the total performance of G. Sulphuraria 074G is 1.7-13.6 times high than the rate of PC production install in open-air(p renominal) S. platensis cultures. (Materassi, 1997) Following those findings we are going to odor whether the production of PC by G. Sulphuraria 074G is appl... '
