This paper presents results concerning the indoor cultivation of selected mixed populations of photosynthetic microorganisms using BG11medium as well as a cheaper medium based on chemical fertilizers and residual glycerol. Preliminary financial evaluations are also presented in order to focus on the economical constraints. The growth of selected oil- containing consortia of photosynthetic microorganisms in 90L of BG11(prepared in spring water) produced in 14 days 285 grams of dry weight biomass containing 28% of lipids; the cost (taking into account only chemicals and water) of 1 Kg of dry biomass means 83.3 lei; whereas the same consortium grown in 30L of alternative medium, prepared with agricultural fertilizers, residual glycerol and spring water produced in 14 days 150g grams of dry weight biomass containing 20% of lipids; the cost (taking into account only chemicals and water) of 1 Kg of dry biomass is 3.2 lei.
