Increased algal growth - by addn of mineral salts to an aq liquid medium to provide a source of protein

摘要

Addn of 40 kg each of NaCl, Na2SO4 and NaHCO3 and of 5 kg each of NaNO3, Na2HPO4 and KCl to 6000 litres of brackish water contg algae, increased the content of algae after growth under artificial illumination and growth.) The improved growth of these spirulina algae contained in the skin provides a valuable source of protein (>60% on dry basis) together with carotenes xanthophylls vitamins and lipoids.
