ABSTRACT
\later extract of cow manure waste enriched with some nItrogen
sources was used as culture media for Chlorella f’Yrenoidosa. The
lowest concentratfOl’l (0.0125%) of the nitrogen soores added to the
cow manure extract affected the highest growth rate. Urea proved to
be the best ni trogen soorce that could be added at low
concentration to the water extract of cow manure waste for single
cell protein production by Chlorella pyrenoidosa. At higher
concentrations, urea proved to be more toxic than both n; trate or
arrmonia.
