In Bangladesh, spirulina is cultured in different agro-industrial wastes such as sugar mill waste effluent, poultry industry waste, fertilizer factory waste, and urban waste and organic matter. The growth parameters of Spirulina platensis grown in the supernatant of digested 4.0 g/litre poultry waste were higher than other cultures on the supernatant of 2.0 and 6.0 g/litre digested poultry waste which might be due to appropriate nutrient content and other environment parameters (Parvin, 2006). Growth performance of Spirulina platensis was studied in three different concentrations of banana leaf ash added with 0.4 g/litre jackfruit seed powder and 0.2 g/litre with urea in the laboratory (Toyub et al., 2005).
