Factor affecting Hydrogen Production from Microalgae

Factor affecting Hydrogen Production from Microalgae

I always interested in utilization of microalgae for biofuel production, including hydrogen. Although I was not involved in certain project related with hydrogen production from microalgae photosynthetic, one of my team member in Energy/Environmental Biotechnology and Biochemical Engineering Department of Chemical Engineering National Cheng Kung University, Taiwan conducted the research. I was regret because I [...]

Utilization of microalgae for CO2 sequestration

Atmospheric carbon dioxide levels have exceeded 450 ppm and are at levels classified as “dangerously high”. CO2 fixation by photoautotrophic algal cultures has the potential to diminish the release CO2 into the atmosphere, helping alleviate the trend toward global warming. Selection of optimal microalgae species is vital to realize workable biological CO2 fixation system

Effect of nutrient supply on microalgae growth

Effect of nutrient supply on microalgae growth

Nutrient availability is an important factor controlling the levels of the primary productivity of photosynthetic organisms. Media with different compositions are supplied to the cells in the form of carbon dioxide, water, and mineral salts in macro or micro quantities.

Effect of carbon dioxide on microalgae growth

Carbon dioxide is another important factor that determine the microalgae growth. It is the carbon source in photoautotrophically growing cells. Usual sources of carbon dioxide for microalgae include atmospheric carbon dioxide, carbon dioxide from exhaust gases, and carbon dioxide chemically fixed in the form of soluble carbonates.

Botryococcus braunii, microalgae rich in hydrocarbon

Bottrycoccus braunii contains extraordinary high level of hydrocarbons, therefore it is potentially capable as the source of primary biofuel. By using several strategies, growth rate and hydrocarbon content of this microalgae can be increased.
