Commercial cultivation of microalgae-an industrial process update
Two types of Scenedesmus sp algal cultures were maintained in indoor open tanks of Aquatic Energy LLC, Lake Charles, Louisiana. The pH, temperature, contamination level, cell count, Chl a, b and OD were taken thrice a day to maintain healthy cultures. Due to water evaporation and rainfall (during summer and winter seasons) water levels were adjusted often. For example, on summer, pH were shoot-up in the morning, during that time CO2 were supplied directly to the ponds to bring down the culture pH normal along with fresh water. On winter due to rainfall, water levels have been increased, these water levels were calculated subsequently nutrients were added close to the paddle wheels (so that nutrients will be mixed thoroughly) to compensate the dilution of the nutrients especially on rainy seasons. N, P, K were used as nutrients to make the product (biomass) cost-effective.
