Growing bacteria in a pure culture so that no other microbes…
Growing bacteria in a pure culture so that no other microbes are present is a mainstay of classical microbiology. Newer testing techniques are able to identify bacteria without having a pure culture, but can instead identify bacteria growing in a mixed culture. 1. What kind of technique, that doesn’t require growing bacteria on a petri plate, could identify a specific bacterium in a mixed culture, and 2. Why would this technique work but using an enterotube fail with a mixed culture?

Identify the catalyst.a. O2b. OI−c. I−d. H2Oe. H2O2 Identify the intermediate:a. O2b. OI−c. I−d. H2Oe. H2O2 Which chemical equation is consistent with the mechanism provided?a. ½ H2O2 + I− → H2O + OI− + O2b. ½ H2O2 + I− → H2O + O2c. 2H2O2 → 2H2O + OI− + O2d. 2H2O2 + I− → 2H2O + O2e. 2H2O2 → 2H2O + O2
