TECHNOLOGY FOCUS - BIOLOGY - Preferred Components: The industry wastewater is the effluent from an agricultural industry. The effluent is obtained from poultry industry, non-poultry meat industry, or plant-based industry. The industry wastewater is obtained from a non-agricultural industry. The population of algal cells comprises freshwater (non-marine) algal strain, several freshwater (non-marine) algal strains, several Cyanobacterial strains, several diatomaceous algal strains or its combination, where at least one species of the population of algal cell is mixotrophic alga. The algal strain of the population of algal cells is isolated from source in contact with the wastewater effluent of an industry. The population of algal cells comprises a strain of an algal chosen from Scenedesmus, Chlorella and Chlamydomonas, Scenedesmus and Chorella, Scenedesmus and Chlamydomonas, Chorella and Chlamydomonas, and Scenedesmus, Chorella, and Chlamydomonas. The algal strain of the population of algal cells is chosen from Chlamydomonas sp., Chlorella vulgaris, Chlorella sorokiniana, Chlorococcaceae sp., Chlorococcum humicolum, Coelastrum microporum, Gloeocystis vesiculosa, Monoraphidium mirabile, Oedogonium sp., Oocystis lacustris, Scenedesmus abundans, S.acuminatus, S.acutus, S.acutus alternans, S.bicaudatus, S.bijuga, Scenedesmus bijuga alternans, S.denticulatus, S.dimorphus, S.incrassatulus, S.obliquus, S.quadricauda, S.quadrispina, S.serratus, Stigeoclonium sp., Ulothrix variabilis, Uroglena sp., Anabaena sp., Aphanocapsa delicatissima, Aphanocapsa hyalina, Aphanothece sp., Calothrix braunii, Chroococcaceae species, Chroococcus minutus, Cylindrospermopsis sp., Leibleinia kryloviana, Limnothrix sp., Limnothrix redekei, Lyngbya sp., Nostoc sp., Oscillatoria sp., O.tenuis, Planktolyngbya limnetica, Raphidiopsis curvata, Synechococcus elongatus, Synechococcus sp., Synechocystis sp., Eunotia sp., Navicula pelliculosa, Navicula sp., Nitzschia palea, Nitzschia amphibia, Nitzschia pura, Gomphonema parvulum, Gomphonema gracile, and Rhodomonas sp.. The population of algal cells is a consortium of algal cells comprising Chlamydomonas globosa, Chlorella minutissima, and Scenedesmus bijuga, and optionally Chlorella sorokiniana. The method further involves isolating the algal biomass from the medium.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The nutritional supplement comprises at least one organic carbon source chosen from glucose, sucrose, arabinose, fructose glycerol, methanol, acetate, plant-based hydrolyzate, and their combination.
