Separation of micro-organisms from meat and their rapid enumeration using a membrane filtration-epifluorescent microscopy technique

Lett Appl Microbiol. 1990 Jan;10(1):23-6. doi: 10.1111/j.1472-765x.1990.tb00086.x.

Abstract

A new method of separating bacteria from beef mince has been developed, in which an alkaline protease, Alcalase 0.6 L, was used to degrade the meat proteins, leaving micro-organisms in suspension. The organisms were then counted, using a membrane filtration-epifluorescent microscopy technique. A correlation coefficient of 0.97 was obtained between this method and the standard plate count, indicating its suitability for use in quality control.
