Geobacillus stearothermophilusSpore Suspension

半岛bd体育手机客户端 说明

一般描述

Detection of antimicrobial residues in meat and other foodstuffs of animal origin is based on agar diffusion, using spores ofGeobacillus stearothermophilusATCC 7953 (sporulation optimized) as test organisms. Antibiotic and sulfonamide residues inhibit the growth of the test organism, which is indicated by the formation of inhibition zones. These inhibition zones remain purple in color whilst the rest of the nutrient medium turns yellow. Cleaning agents, disinfectants and preservatives do not influence the test.

应用

TheGeobacillus stearothermophilusspore suspension is used in a routine qualitative procedure to detect antimicrobial residues such as antibiotics, sulfonamides and other chemotherapeutics in meat and other foodstuffs of animal origin. It is used in conjunction with the test agar for performing the antibiotics sulfonamide residue test according to KUNDRAT (1.10662).
