Abstract
Spirulina grows relatively slowly, with an output of c. 5 g dry mass m-2 day-1, in a medium of solid cattle waste extract in water containing NaCl at 10 g litre-1. In this study the growth rate and output rate were very substantially increased when the waste-based medium was fortified with carbon, nitrogen and phosphorus. The initial growth rate of batch cultures grown on the fortified cattle waste medium approximated to that of cultures grown on standard Spirulina growth medium. Aeration of the algal cultures considerably improved the output rate of algal biomass.
