    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 is adhered to the base or the coversheet in the growth compartment. A cold water-soluble gelling agent and an effective amount of a dry carbon dioxide-generating reagent are adhered to the at least one adhesive layer. The carbon dioxide-generating reagent consists essentially of particles having a diameter of less than 106 microns.

    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.
