      Four types of agroindustrial waste products were tested for their suitability as substrates for Chlorella single-cell protein production. Based on cell density on day 7, unsterilized rice straw filtrate, Tris-buffered inorganic medium (control), unsterilized slop (1%) and unsterilized rice hull filtrate were suitable culture media. Dry weight yield after two weeks did not vary among media. Gross protein content of algae was highest in rice straw with or without sterilization. Substrates for algal SCP production are assessed on the basis of their nutrient content, pH, and hygienic acceptability.
