The membrane filter technique for estimating numbers of viable bacteria: some observed limitations with certain species.
The membrane filter, also known as molecular filter, is valuable for its ability to permit passage of large volumes of fluid and yet retain on its surface particles of bacterial size. The history of its development and some of its properties have been reviewed by Goetz and Tsuneishi (1951). Other properties and specifications are available from the manufacturers.3 At present details of manufact...
متن کاملMembrane filter technique for the isolation of Yersinia enterocolitica.
A membrane filter procedure was developed for the isolation of Yersinia enterocolitica from aquatic environments. Primary differentiation was based on the fermentation of sorbitol, the absence of lysine decarboxylase and arginine decarboxylase-dihydrolase activities, and the production of urease. Sodium deoxycholate was incorporated as an inhibitor of background organisms. The presumptive ident...

Revival and subsequent isolation of heat-injured bacteria by a membrane filter technique.
Cultures containing mixed flora from raw milk were heated at 62.8 C for 15, 20, 25, and 30 min. Dilutions were filtered through membrane filters, and the filters were incubated on Trypticase soy broth (TSB) and on TSB plus NaCl (TSBS). The TSB count indicated the total population which survived heating and included injured and uninjured cells. The colonies on TSBS indicated the uninjured cells ...
