Microbiological laboratories need a simple procedure to maintain important microorganisms rather than repetitive sub-culturing, which results in contaminated cultures, loss of viability and, even more importantly, loss of original characteristics by introducing biochemical and genetic changes. Cryoinstant consists of 25 porous beads in a vial filled with a broth containing glycerol. Microorganisms will bind to the porous surface of the beads. The excess broth is aspirated, and the vials stored at temperatures down to –70 °C in a freezer.

For the antibiotic sulphonamide residue test according to Kundrat. The Geobacillus stearothermophilus spore suspension is used in conjunction with the test agar for performing the antibiotic sulphonamide residue test according to Kundrat, Cat. No. 1.10662. The test detects antimicrobial residues such as antibiotics, sulphonamides and other chemotherapeutics in meat and other foodstuffs of animal origin. It is a routine qualitative procedure. The test is based on agar diffusion, using spores of Geobacillus stearothermophilus as test organisms. Antibiotic and sulphonamide residues inhibit the growth of the test organism. Cleaning agents, disinfectants and preservatives do not influence the test.

The catalase test can differentiate or identify microorganisms by checking their ability to produce catalase, an enzyme that protects microorganisms from toxic oxygen metabolites. Usually only aerobic microorganisms produce catalase.
