New Bioresource Technology Study Findings Recently Were Reported by Researchers at University of Technology

June 18, 2014

By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Bioresource Technology have been published. According to news reporting originating in Johor Baharu, Malaysia, by NewsRx journalists, research stated, "Wavelength of light is a crucial factor which renders microalgae as the potential biodiesel. In this study, Tetraselmis sp. and Nannochloropsis sp. as famous targets were selected."

The news reporters obtained a quote from the research from the University of Technology, "The effect of different light wavelengths on growth rate and lipid production was studied. Microalgae were cultivated for 14 days as under blue, red, red-blue LED and white fluorescent light. The growth rate of microalgae was analyzed by spectrophotometer and cell counting while oil production under improved Nile red method. Optical density result showed the microalgae exhibited better growth curve under blue wavelength. Besides, Tetraselmis sp. and Nannochloropsis sp. under blue wavelength showed the higher growth rate (1.47 and 1.64 day(-1)) and oil production (102.954 and 702.366 a.u.)."

According to the news reporters, the research concluded: "Gas chromatography analysis also showed that palmitic acid and stearic acid which were compulsory components for biodiesel contribute around 49-51% of total FAME from Nannochloropsis sp. and 81-83% of total FAME from Tetraselmis sp."
