Bacteria immobilized by adsorption on an inorganic carrier are stabilized by carrying out the adsorption procedure in the presence of from about 1 to about 20% weight per volume of sucrose of nonfat dry milk solids and lyophilizing the adsorbed bacteria.

Stabilization of immobilized bacteria

This invention is concerned with the use of fluorocarbon and silicone oil greases or gels to stimulate the growth of various microorganisms. More particularly, the instant invention contemplates the addition of a peroxide compound, preferably hydrogen peroxide (H.sub.2 O.sub.2), to fluorocarbon and silicone oil greases or gels to further stimulate the growth of anaerobes and facultative anaerobes in liquid or solid nutrient media.

Means for stimulating microbial growth

Microbial culture device containing a growth medium having incorporated therein a lipophilic fluorescent material and means associated therewith for localizing and identifying the growth of colonies of an unknown microbe, and a known gram positive microbe, and/or a known gram negative microbe. The device can be used to determine whether an unknown microbe sample is gram positive or gram negative by culturing the unknown on the medium and then comparing the fluorescence of the unknown microbes with fluorescence of similarly cultured gram positive and/or gram negative microbes.

Method for distinguishing gram positive and gram negative microbes

A deoxygenated, inert, oil-like fluid having an oxygen activity coefficient less than that of water may be used to provide anaerobic conditions for the transport and/or storage of anaerobic specimens.

Anerobic specimen transport system

Solidified, polar, micorbial growth medium containing 8-anilino-1-naphthalenesulfonic acid or a salt thereof. Microbial colonies grown on the medium can be detected fluorimetrically.
