In a preliminary screening, several yeast species were selected among which Endomycopsis fibdigera and Schwunniomyces castellii showed a high yield when inoculated in potato or potato peel media. Both these species were found to have an elevated protein percentage and a good amino acid composition. The effect of some cultural conditions on SCP (single cell protein) production by S. castellii grown on potato medium in a pilot plant 90 1 fermenter was also investigated. Optimal conditions resulted in employing a substrate containing 80 g/l of potatoes, 5.0 8/1 of cornsteep liquor, at 28°C, with a 3% inoculum. S. castellii and E. fibdigera were also separately inoculated in solid and semi‐solid substrates (potatoes, cassava flour, stale bread, maize flour). Under laboratory and semi‐pilot plant conditions, carbohydrate conversion into protein was more effective on potato and cassava flour media.
