Science Lab - Phycocyanin

Introduction\nPhycocyanin(PC) is a blue photopigment used for some applications, for example as a natural food colorant in the food industry (e.g. M&M and Gatorade). This pigment is peed by a natural play of the red microalga G. Sulphuraria (strain 074G). This kind of algae good deal grow in sun run dry(a) situations. It can produce in the immorality, on sundry(a) organic compounds and at various Ph. values. Phycocyanin is tack together only in cyanobacteria, Cryptophyceae and Rhodophyceae, is among the most classic substances produced uniquely in cyanobacterial and microalgae cultures. The commercial labor of PC is done in phototrophic cultures of the cyanobacterium Spirulina plantensis. The postcode source for this is sun deject. Because these cultures depend on the sun glisten, or externally supplied light it is very hard to master up these cultures without losing productivity. This is because the surface playing area to volume ratio decreases at increasing scale and the light paths inside the cultures get longer. This causes self-shading and dark and this develops unproductive zones. (Eriksen J. K., 2005)\nThe algae Galdieria Sulphuraria, can grow photo-, mixo and heterotrophically in warm up acidic springs and can subdued produce PC. As told in advance the strain 047 G of G. sulphuraria does take down so when it is grown heterotrophically in darkness. (Schnarrenberger, 1995) High tramps of biomass which is accomplishable in high-cell-density fed-batch cultures of G. sulphuraria 074G compensates for the relative depressive disorder PC concentration in the algae; 3-4 mg g-1 of biomass dry weight in parity to the phototrophic Spirulina platensis; 60-74 mg g-1 dry weight. Altough thither is a big remnant between the amount of PC per cell the total production of G. Sulphuraria 074G is 1.7-13.6 times higher than the rate of PC production found in outdoor S. platensis cultures. (Materassi, 1997) following(a) those findings we are going to explore whether the production of PC by G. Sulphuraria 074G is appl...
