Abstract
A process for trapping and confining microorganisms in air using water-soluble polymers is disclosed. The water-soluble polymers are readily soluble in water or a physiological diluent, have reasonable mechanical strength so that they can be transported without rupture, retain water and adhere to microorganisms. A process for the rapid and sensitive detection of microorganisms in air under aseptic conditions is also disclosed.
Claims3
A process for trapping and confining microorganisms in air for analysis, said process comprising the steps of:
- (a) casting a water-soluble polymer;
- (b) placing said water-soluble polymer in an area to be monitored for microorganisms;
- and
- (c) collecting microorganisms present in the air on said water soluble polymer, wherein said water-soluble polymer has a degree of hydrolysis between 70% to 90% and a water equilibrium content between 1% to 50% w/w % and is soluble in water or other physiological diluents.
