The need for renewable sources of energy has become critical as fossil fuel resources, which include oil, coal, and natural gas, are known to contribute to climate change and will eventually be depleted. Biofuels that originate from the fat of plants, animals, microalgae, and bacteria are an attractive alternative. Microalgae, in particular, are strong candidates for biofuel production since they have a high growth rate and lipid content (up to 50 in some species). The goal of this research was to optimize 3N-BBM+V recipe (Bold Basal Medium with 3-fold Nitrogen and Vitamins) in an effort of reducing the amount of …

The individual components of the growth media, notably magnesium, have a profound impact on the growth and lipid production of the green microalgae, Scenedesmus dimorphus. The goal of this work was to investigate these effects and explain the causes via multiple experiments. It is important to understand the aspects of algal growth because they have a significant impact on the commercial viability of microalgal lipids as a potential feedstock for biofuel production. Digestate, derived from bovine waste and a potential cost effective nutrient replacement for conventional media types, was found to maximize growth and lipid concentration in S. dimorphus at …

Increasing gas prices, limited fossil fuel resources and U.S. dependence on foreign oil make research in alternative fuels a priority. The feasibility of producing fuels from microalgae is economically dependent on improvements in lipid productivity by the algae. The research presented here focuses on the development of a mathematical model to describe the biomass and lipid productivity in a continuously-operated photobioreactor (PBR) system. Five different cell lysing methods were evaluated for the purpose of improving the methods of analysis of lipid synthesis. The two most promising methods were found to be mortar and pestle and organic solvent cell fractionation methods. …
