Bacterial SCP from methanol in Kuwait: Product revovery and composition

The rationale behind KISR's involvement in SCP is explained and emphasis towards the use of aerobic thermophilic/thermotolerant methanol-utilizing bacterial cultures is stressed. An attempt is made to correlate different pilot plant harvesting procedures for biomass recovery with product quality. The latter is expressed as crude and true protein content, moisture and ash content, mineral composition of the ash, and amino acids profiles. The most suitable harvesting procedures were found to be those using a mild heat-acid or acid-heat treatment. Both of these procedures gave high recovery efficiencies and suitable product nutrition.
