Development of Multivariate Model on the Effect of Different Parameters on Synechococcus sp. PCC 7002 Growth

Understanding of the correlative effects of combined variables on the growth rate of the cyanobacteria is fundamental to the exploitation of cyanobacteria as a biological mechanism to produce biofuels. Cyanobacteria (blue-green algae) are phototrophic microorganisms that offers attractive benefits,...
