    • The invention is directed to compositions and methods for collecting, transporting, and storing, without refrigeration, biological materials, which may comprise samples of biological, clinical, forensic, and/or environmental origin. These compositions preserve the viability of the collected organisms and/or the RNA/DNA and proteins in the sample composition mixture and permit the long-term storage of samples. Compositions are compatible with subsequent manipulation of the sample, including propagation and culture of the collected microorganisms, or isolation, purification, detection, and characterization of proteins, nucleic acids, and other macromolecules. When the compositions containing microorganisms and any polynucleotides therein are further processed, such as by nucleic acid testing, there is an increased ability to detect, isolate, purify and/or characterize select microbes and their components, such as nucleic acids, when compared to conventional microbial transport media that contain interfering substances and RNA/DNA extraction is not required prior to PCR analysis. In particular, the compositions disclosed allow for the collection, transport and storage of biological samples for extended periods at ambient temperature, while maintaining the integrity of the macromolecules of the sample for subsequent extraction, identification, and quantitation.
