✦ Synopsis
The possibility to use microorganisms as human food is limited by several factors. The intact cell is resistant to digestion, the cell wall is unbalanced in essential amino acids, and the nucleic acids are said to be harmful. For using single cell protein as food it may thus be necessary to disrupt the cell wall and separate the protein from nucleic acid. This paper is concerned with the production and properties of extracellular enzymes able to lyse cell walls of microorganisms. Soil bacteria and actinomycetes have been cultivated and lytic enzymes from these organisms have been used to lyse living cells of the yeast like organism E . ashbyii. Efforts were also made to use these enzymes for lysing cell of a Methummanas s p .
