Abstract

Algal nutrient solutions or culture medium are made up of a mixture of chemical salts and water. The culture medium provides the nutrient needed for the growth of algae. These nutrients solutions are formulated specifically for its use in aquatic environments and their consistency is more precise for laboratory culture. The culture medium is constituted with the addition of macronutrients, micro nutrients and vitamins. Macro nutrients include nitrate, phosphate and silicate. Micro nutrients contain various trace metals. Vitamins like thiamin (B1), cyanocobalamin (B12) and sometimes biotin (B7) are commonly required for the growth of most of the micro algae.
