White LEDs provide the necessary blue light for chlorophyll absorption, and they also emit enough green and red wavelengths to support the activity of phycobiliproteins in some microalgae species. The spectral composition of white LEDs varies depending on the specific product and manufacturer, so it's essential to choose a white LED with a spectrum suitable for the particular microalgae species you want to grow. For example, cool white LED lights have more blue light compared to warm white LED lights. This difference can be relevant to the aim of the algae culture. For instance, a higher blue spectrum can promote the production of carotenoids such as astaxanthin and fucoxanthin. Therefore, using cool white LEDs with higher blue light might increase the production of these carotenoids. For more information have a look in the following article: Article The potential of manipulating light in the commercial produc...
White LEDs can be used to grow microalgae instead of fluorescent tube lights. LEDs are more energy-efficient, have a longer lifespan, and can provide specific light spectra that suit microalgae growth. They generate less heat, are compact, and allow for adjustable light intensity. Using white LEDs is an environmentally friendly and effective method for microalgae cultivation.
Yes you can, while LEDs have many advantages over fluorescent tubes, please see my attached presentation!
All the best for you,
