title: [Immunochemical method for study and identification of unicellular organisms (yeasts and bacteria) incorporated into food products as a protein source].
abstract: The expected increase and diversification of single cell proteins production already requires the development of convenient methods for the identification of producing strains from the processed S.C.P., i.e. killed and dried cells. A simple immunological method based on double immunodiffusion analysis is proposed, that enables the identification of Toprinal L (Candida tropicalis), Toprina G (Candida lipolytica) and Pruteen (Pseudomonas methylotropha), all S.C.P. having received an approval from different european countries. Sensitivity and specificity are high enough to enable the identification of these products mixed to feeds in concentrations as low as 5 p. cent (1 p. cent with Pruteen).
