Production of Spirulina platensis by adding sodium bicarbonate and urea into chicken manure medium

Hilal Kargin Yilmaz, Ozlem Sezgin

Abstract


In this study, dry chicken manure (DCM) was used as the source of nitrogen in the production of Spirulina platensis. Experiment was conducted in two different types of nutrition. In the type I nutrition, the highest average cell increase was recorded as 289.70 filaments mL-1 in value in the type I group (DCM+urea). In the type II nutrition, the highest average cell increase was recorded as 296.50 filament mL-1 in value in the type II group (DCM+urea+sodium bicarbonate). In the type I nutrition (DCM+Urea), the highest specific growth rate was detected as 0.21 division day-1 on the sixth day and k value as being 0.30 division day-1. In the type II nutrition, the highest specific growth rate was recorded as 0.08 division day-1 in the group II (DCM+Urea+NaHCO3) and k value as being 0.12 division day-1. In both types of nutrition, the protein rates of the type I group (DCM+urea) and the group III (DCM+sodium bicarbonate) are found to be higher than that in the other groups. The lipid levels in both types of nutrition, in DCM (Control) and in the type I group (DCM+Urea) were found to be higher than the other groups.
