US 4,229,544 A · Living organism packaging

Abstract

A method of packaging, and the package so produced, for maintaining living organisms viable for a long period of time. The living organisms, such as bacteria, fungi, algae, etc., are mixed with a carrier, such as peat. The organism-carrier mixture is then disposed in a package, such as a heat-sealable plastic envelope, and a gaseous atmosphere is provided in the package effective to induce and maintain substantial nonvegatative state formation of the organisms. Some organisms will form cysts, others spores, but whatever nonvegetative state is assumed, the organisms will be much less susceptible to heat, cold, starvation, and other adverse environmental factors. Suitable gaseous atmospheres include nitrogen, helium, and argon gases. The package is then sealed to prevent contamination of the atmosphere therein.

Dependent claims

A method of packaging living organisms consisting essentially of the steps of

mixing the living organisms with a carrier comprising substantially granular material suitable for maintaining the organisms in a viable condition over a long period of time,
disposing the organism-carrier mixture in a package,
providing a gaseous atmosphere in the package effective to induce and maintain substantial nonvegetative state formation of the organisms, and
sealing the package to prevent contamination of the atmosphere therein until breakage of the seal just before use of the organisms.
