CultiControl microorganisms are lyophilized, reference stock culture preparations containing a single strain of a microorganism. These microorganism preparations are intended to be used for quality control of culture media, educational/instructional programs and industrial applications. The microorganism preparations are derived from ATCC® (American Type Culture Collection) and NCTC® (National Collection of Type Cultures, operated by the UK Health Security Agency (UKHSA)). CultiControl microorganisms are packaged in a resealable vial that contains five (5) lyophilized pellets of a single microorganism strain and a desiccant to prevent adverse accumulations of moisture. Quanti-CultiControl are lyophilized, quantitative microorganism preparations to be used in industrial laboratories for Quality Control purposes. Processed as directed, these preparations provide a challenge of < 100 CFU per 0.1 mL, which is a concentration usually suitable for several pharmaceutical applications, including growth promotion testing of culture media to be employed in sterility testing. These microorganism preparations are derived from the American Type Culture Collection (ATCC®). Quanti-CultiControl are suitable for the Growth Promotion Test recommended by the international Pharmacopoeiae, without need of intermediate dilution steps, since each rehydrated suspension generates less than 100 UFC for 0.1 mL inoculum. Each suspension (1 mL) allows 10 inocula.
