<\/a>Abstract<\/strong><\/p>\n

Lack of high-density algal photobioreactors (PBR) has been a limitation in exploiting the biotechnological potential of algae. Recent developments of highly efficient light-emitting diodes (LED using gallium aluminum arsenide chips) have made the development of a small LED-based PBR possible. We have calculated theoretical values of gas mass transfer requirements and light-intensity requirement to support high-density algal cultures for the 680 nm monochromatic red light from LED as a light source. A prototype PBR has been designed based on these calculations. A cell concentration of more than 2 \u00d7 109 cells\/mL (more than 6.6% v%sol;v), cell doubling times as low as 12 h, and an oxygen production rate as high as 10 mmol oxygen\/L culture\/h were achieved using on-line ultrafiltration to periodically provide fresh medium.<\/p>\n

About Oilgae – Oilgae – Oil & Biodiesel from Algae<\/a><\/strong> has a focus on biodiesel production from algae while also discussing alternative energy in general. Algae present an exciting possibility as a feedstock for biodiesel, and when you realise that oil was originally formed from algae – among other related plants – you think “Hey! Why not oil again from algae!”<\/p>\n
