32 Prokaryotes Living Organisms ph: 800.334.5551 We label each bacteria culture with genus and species name, medium on which it is cultured, and temperature for optimal growth. 155000P Carolina BioKits: Antiseptic Versus Disinfectant Sensitivity Classroom Kit (with perishables) Carolina BioKits®: Antiseptic Versus Disinfectant Sensitivity Kit Do your students understand the relative effectiveness of disinfectants and antiseptics? Both contain chemical compounds that either inhibit or kill microorganisms. This kit enables students to discover through experimentation the relative effectiveness of 5 common disinfectants and antiseptics on Escherichia coli, a Gram-negative bacterium, and Bacillus cereus, a Gram-positive bacterium. The Demonstration Kit is for a teacher or student working individually; the Classroom Kit is for a class of 30 students working together in 10 groups of 3.

Students perform 2 sterile exercises: the transfer of sterile nutrient broth to a culture tube and the transfer of sterile nutrient broth from a culture tube onto a nutrient agar plate. Students must be able to perform both of these exercises without introducing unwanted microorganisms and understand the use of a positive control. Kit includes materials sufficient for 10 groups of 3 students.
