  • Title: Electropositively charged filters for the recovery of yeasts and bacteria from beverages.
    Author: Thomas DS.
    Journal: J Appl Bacteriol; 1988 Jul; 65(1):35-41. PubMed ID: 3209514.
    Abstract:
    The ability of electropositively charged filters to recover yeasts and lactic acid bacteria from a variety of beverages was evaluated. Filtration through 'Zeta plus', grade O5S, filters recovered nearly all of the yeast contaminants from table wines, sherry and port. Recovery of yeasts from cream liqueurs and egg-based beverages was also good but it was not possible to filter drinks containing orange juice, even through filters with nominal pore sizes of 2 to 10 micron. Lactic acid bacteria proved more difficult to recover than yeasts, even though smaller pore-sized filters (1 to 4 micron) were employed. However, a sufficiently high percentage of bacteria were recovered to justify use of these filters for quality assurance. The advantage of concentrating contaminants by using charged filters, and the influence of product composition on the efficiency of microbial adsorption are discussed. The growth of wine-spoiling yeasts and lactic acid bacteria were not inhibited by water- or ethanol-soluble extracts of the filter material.
