Development of Techniques and Conditions for Large-scale Production of Microalgal Biomass
Microalgae are evaluated as a renewable resource of biomass for the production of biofuels as well as other biomaterials. Locally isolated algal strain was chosen for the study of optimum cultivation conditions that will allow the maximum production of biomass in a large-scale. Conditions tested were the amount and frequency of the nutrients and carbon dioxide added to the algae culture. The growth of microscopic algae in the culture was indirectly monitored by measuring the optical density with a spectrophotometer. Different types of nutrient media that had been developed in the lab were evaluated for their effect on the growth rate. We have also examined the strategy for algae harvesting by continuously removing 20, 50 or 90% batch of the culture volume when algae reach the maximum growth. The long-term cultivation and harvesting of the particular algal strain yielded the most biomass when the 90% batch harvesting strategy was employed.
