Using light in different wavelength ranges to estimate algae growth stage and algae growth rates.
NASA has invented a novel technology for estimating algae growth stages and lipid content using light absorption or reflection in selected wavelengths. This invention provides simultaneous information about both algae growth and lipid content and it does not depend solely on the time of growth. It implicitly includes variables due to environmental parameters such as nutrient deprivation or other stresses. This is helpful for subsequent processing of the algae into nutraceuticals, pharmaceuticals, animal feed, fertilizer, or biofuels.
