  • Isolation of microbial protein with reduced nucleic acid content
    Patent number: 4330464
    Abstract: The present invention relates to a process for the isolation of protein from microbial cells. The microbial cells are subjected to a treatment to disrupt the cell walls thereby producing a cellular debris fraction and a fraction containing protein and nucleic acid. The two fractions are separated and the fraction containing the protein and nucleic acid is treated with a chelating agent at a pH in the range of 5.5 to 7.0. The resulting solution is passed through an anion exchange column which selectively adsorbs the nucleic acid. The protein is recovered from the resultant eluate.
