'Science Lab - Phycocyanin'

' entering\nPhycocyanin(PC) is a blue angel photopigment used for galore(postnominal) applications, for example as a rude(a) food colorant in the food pains (e.g. M&M and Gatorade). This pigment is realised by a essential mutant of the rose-cheeked micro alga G. Sulphuraria (strain 074G). This kind of algae behind evoke in mixed situations. It can nurture in the sombre, on various constitutive(a) compounds and at various Ph. values. Phycocyanin is found solely in cyanobacteria, class Cryptophyceae and Rhodophyceae, is among the most eventful substances produced uniquely in cyanobacterial and microalgae cultures. The commercialised performance of PC is done in phototrophic cultures of the cyanobacterium Spirulina plantensis. The energy cite for this is sunlight. Because these cultures depend on the sunlight, or externally supplied light it is precise hard to exfoliation up these cultures without losing productivity. This is because the line up area to intensivene ss ratio decreases at increasing eggshell and the light paths inwardly the cultures get longer. This causes self-shading and dark and this develops unproductive zones. (Eriksen J. K., 2005)\nThe algae Galdieria Sulphuraria, can invoke photo-, mixo and heterotrophically in potent acidic springs and can still produce PC. As told earlier the strain 047 G of G. sulphuraria does even so when it is grown heterotrophically in darkness. (Schnarrenberger, 1995) High grade of biomass which is possible in high-cell-density fed-batch cultures of G. sulphuraria 074G compensates for the relative subaltern PC niggardness in the algae; 3-4 mg g-1 of biomass dry weight in comparison to the phototrophic Spirulina platensis; 60-74 mg g-1 dry weight. Altough in that respect is a hulky difference amidst the amount of PC per cell the get achievement of G. Sulphuraria 074G is 1.7-13.6 time higher than the rate of PC production found in outdoor S. platensis cultures. (Materassi, 1997) chase those findings we are going away to look whether the production of PC by G. Sulphuraria 074G is appl... '
