ABSTRACT:
A package for storing, incubating or transporting an anaerobic culture comprising a bag of flexible sheet material of low gas permeability, a self-contained gas generating apparatus in the bag for generating at least a reducing gas, a culture retaining container in the bag, and a catalyst in the bag which promotes reaction between the reducing gas, when produced by the gas generating apparatus, and oxygen in the bag. The bag may also contain a color indicator apparatus which when activated indicates the presence or absence of oxygen in the bag by color change. Hydrogen is the preferred reducing gas which is generated, alone or in conjunction with carbon dioxide.
