Abstract
The present invention relates to a method for the separation of adsorbents from growth media, utilizing polymeric dispersants. These dispersants or flocculating agents have been found to efficiently separate beneficial adsorbents without significantly changing the viable microorganisms for further testing.
Claims31
A method for testing for microorganisms in a growth medium comprising a microorganism and an adsorbent, said method comprising the steps of:
- providing a sample of the growth medium that comprises a microorganism and an adsorbent;
- adding a polyacrylamide dispersant to the sample;
- permitting the adsorbent to separate from the medium;
- and
- testing the growth medium from which the adsorbent has been separated for the presence of the microorganism.
A method for the separation of an adsorbent from a growth medium comprising the adsorbent, said method comprising the steps of:
- adding a polyacrylamide dispersant to the growth medium;
- and
- permitting the adsorbent to separate from the medium.
A device for the enhanced recovery and detection of microorganisms, said device comprising a sealable, sterilizable, specimen container, having an internal chamber in which a sample comprising a microorganism may be cultured, the internal chamber enclosing a sample comprising a microorganism, a sterile culture medium, an adsorbent in an amount that is effective for neutralizing, binding, or inhibiting antimicrobial substances present in said sample and said medium, and a polymeric dispersant that interacts with the adsorbent, the container having at least one transparent section therein.
In a method for cultivating microbial organisms in a liquid growth medium to which an adsorbent has been added to adsorb antimicrobial materials, an improvement comprising adding a polymeric dispersant to the growth medium to precipitate the adsorbent.
