TECHNOLOGY FOCUS - BIOLOGY - Preferred Method: The method further comprises producing a material from the microalgae; and processing the material to produce a processed material. Preferred Components: The microalgae is: a Botryococcus strain, preferably a UTEX 2629 (Botryococcus sudeticus) strain, a UTEX 2441 strain (Botryococcus braunii strain); a Neochloris strain, preferably a UTEX 1185 strain (Neochloris oleabundans strain); a Chlamydomonas strain, preferably a UTEX 2243 strain (a Chlamydomonas reinhardtii strain); or a strain comprising a photoreceptor. The fruit wastewater is raisin wastewater or wine wastewater. The light: is a low irradiance (intensity) of light of 3-5 mu mol photons/m2/second; and is produced by a natural light source and is natural sun light, and comprises full spectrum light or a specific wavelength of light, or by an artificial light source and is artificial light. The intensity of the light is 0.01-1 mu mol photons/m2/second, 1-10 mu mol photons/m2/second, 10-100 mu mol photons/m2/second, 100-300 mu mol photons/m2/second, 3-4 mu mol photons/m2/second, 2-3 mu mol photons/m2/second, 1-2 mu mol photons/m2/second, or 3-5 mu mol photons/m2/second. The growth rate of the microalgae is higher than a second microalgae incubated under a second heterotrophic growth condition for a period of time sufficient to allow the microalgae to grow, where the second heterotrophic growth condition comprises a growth media comprising a non-wastewater carbon source. The fruit wastewater is the only carbon source (glucose or sugar source) in the media. EXAMPLE - Neochloris oleabundans UTEX 1185 strain was grown in Erlenmeyer flask (250 ml) containing 120 ml modified bold 3 N medium (comprised of sodium nitrate (8.82 mM), dipotassium hydrogen phosphate (0.43 mM), magnesium sulfate heptahydrate (0.3 mM), calcium chloride dihydrate (0.17 mM), potassium dihydrogen phosphate (1.29 mM), sodium chloride (0.43 mM), P-IV metal solution (comprised of disodium EDTA dihydrate (0.75 g), ferric chloride hexahydrate (0.097g), manganese chloride tetrahydrate (0.041 g), zinc chloride (0.005 g), cobalt chloride hexahydrate (0.002 g), sodium molybdenum oxide dihydrate (0.004 g) in deionized water (1 l)) (6 ml), 1 ml of each of three vitamins (B12 (0.1 mM), biotin (0.1 mM), thiamine (6.5 mM), in deionized water (1 l)) with 2% glucose at 25 degrees C with an aluminum foil loosely covering the flask on an orbital shaker at 130 rpm under alternating two 40 W natural sunshine and two 40 W plant and aquarium fluorescent light bulbs to obtain the initial culture of the Neochloris oleabundans UTEX 1185 strain, and its concentration was measured using optical density at 680 nm and 750 nm.
