A microbial culture apparatus including an outer sealable enclosure for receiving a culture retaining container and a self-contained anaerobic gassing and indicator apparatus which can be selectively activated to provide a gaseous atmosphere around the culture retaining container. The gassing and indicator apparatus includes an open top receptacle having a first rupturable container for producing a gaseous atmosphere, a second rupturable container containing a color indicator, and a catalyst, and a cover for the receptacle arranged to rupture both rupturable containers when the cover is moved to a closed position to activate the gassing and indicating apparatus. The outer enclosure comprises an outer open top receptacle for receiving the culture retaining container and the gassing and indicator apparatus, and a cover which can be moved to a closed position sealing the outer receptacle and activating the gassing and indicating apparatus.
