Value in wastewater

Just Science

Last week, I presented illustrations for yeast and a microalgal species of Chlamydomonas. Today I will expound on part of this. Ongoing research is working to identify ways to circumvent the need for fresh water, a precious commodity, and costly fertilizer to cultivate microalgae for biofuel production. These microorganisms are a rich source of oils that can be integrated into our national fuel infrastructure. However, growing the amount of microalgae necessary to decrease our need for petroleum based fuel relies on a precious and ever deminishing resource, fresh water. Also needed are nutrients like nitrogen and phosphorous, usually in the form of fertilizer.

Microalgae are adaptable to environmental changes. Recent research shows several microalgal species that can be cultivated with no need for freshwater. Instead, these species, Chlamydomonas globosaChlorella minutissima and Scenedesmus bijuga, are grown in something we have plenty of; wastewater.

These microalgae are…
