Abstract

In this study, a novel symbiotic bacterium (Stenotrophomonas maltophilia) was isolated from algae culture and cocultured with the abundant species Chlorella pyrenoidosa and Scenedesmus abundans in 3 N BBM+V medium under aseptic conditions. Furthermore, an optimization study was carried out to maximize the growth of the algae biomass. The independent parameters used to determine the bacterial inoculum concentration, pH of the medium, aeration rate of the culture system and other known parameters were temperature, light intensity, inoculum volume of algae and culture time. Thus, the effect of the bacterial inoculum concentration was studied by varying the concentration by 0, 2, 4, 6, 8 and 10%. The initial pH of the medium was changed by changing the medium pH via buffer solutions. The culture system aeration rate was the foremost important factor for determining the actual outcome of the product. Therefore, to determine the influence of the aeration rate in the system, different ranges of volumetric oxygen rates were tested: 90, 80, 70, 60, 50, 40, and 30%. The results showed that the optimal values for maximum biomass production were 8% bacterial inoculum concentration, 7% pH of the medium, and 90% aeration rate.
