Abstract: Provided is a method of forming a fibrinogen hydrogel composition, the method including providing a fibrinogen hydrogel or precursor thereof, comprising fibrinogen hydrogel forming salt. The fibrinogen hydrogel forming salt concentration is greater than or equal to the threshold concentration to form a fibrinogen hydrogel. The method further includes denaturing the fibrinogen hydrogel such as by heating. The method optionally further includes combining the fibrinogen hydrogel with a carrier material. When present, the concentration of the carrier material typically ranges from 0.1 to about 50 wt.-%. The method further includes reducing the salt concentration below the threshold concentration to form a fibrinogen hydrogel.

Abstract: The present disclosure provides a culture device for enumerating colonies of microorganisms. The device can comprise a base, a coversheet, and a nonporous spacer member disposed therebetween. The spacer member comprises an aperture that defines a growth compartment. At least one adhesive layer adhered to the base or the coversheet in the growth compartment. A cold water-soluble gelling agent and a dry oxygen-scavenging reagent are adhered to the at least one adhesive layer. The oxygen-scavenging reagent consists essentially of particles having a diameter of less than 106 microns.

Abstract: A self-contained anaerobic environment-generating culture device is provided. The culture device includes a first substrate having opposing inner and outer surfaces, a second substrate having opposing inner and outer surfaces, a growth region disposed between the inner surfaces of the first and second substrates, an effective amount of a substantially dry enzyme component of an enzyme-mediated oxygen depletion system, an effective amount of a substantially dry enzyme substrate component of the enzyme-mediated oxygen depletion system, and a dry, cold-water-soluble gelling agent disposed in the growth region. The enzyme and enzyme substrate components are disposed in coatings in the growth region. The first and second substrates are substantially nontransmissible to gaseous oxygen. Methods of making and using the culture device area also provided.

Abstract: The present disclosure provides a culture device for enumerating colonies of microorganisms. The device can comprise a base, a coversheet, and a nonporous spacer member disposed therebetween. The spacer member comprises an aperture that defines a growth compartment. Disposed in the growth compartment are a cold water-soluble gelling agent, a dry oxygen-scavenging reagent, a dry buffer system, and an effective amount of a dry carbon dioxide-generating reagent. The buffer system is selected such that, when the growth compartment is hydrated with a predetermined volume of deionized water, an aqueous mixture with a pH less than or equal to 6.35 is formed.

Abstract: The present disclosure provides a culture device for enumerating colonies of sulfate-reducing microorganisms. The device includes a body having a waterproof base, a waterproof coversheet attached to the base, and a growth compartment disposed therebetween. The growth compartment has a perimeter and an opening. A portion of the perimeter is defined by a waterproof seal. The portion can include >50% of the perimeter. Disposed in the growth compartment are a dry cold water-soluble gelling agent, a dry culture medium selected to facilitate growth of a sulfate-reducing bacterium or indicator reagent for detecting hydrogen sulfide production by a sulfate-reducing bacterium, and a dry first oxygen-scavenging reagent.

Abstract: A culture system for culturing a microaerophilic or an anaerobic microorganism is provided. The culture system can include effective amounts of i) an enzyme of an oxidoreductase family and ii) a substrate for said enzyme, a container, and a predetermined volume of aqueous medium that supports growth of said anaerobic or microaerophilic microorganism. The enzyme can be selected from a group consisting of ascorbic acid oxidase and laccase. The effective amounts are effective to deplete dissolved oxygen in the predetermined volume to a concentration that facilitates growth of a microaerophilic microorganism or an obligately-anaerobic microorganism. A method of using the system is also provided.
