Given sugar solutions: fructose, galactose, arabinose, glucose, maltose, sucrose, lactose, starch and water. Which of the sugar undergo fermentation? Which does not? Why? What is the purpose of this test? How are carbohydrates differentiated by this test? What is the reaction involved in this test

The second pic are the answer choices

How would changing the type of bread (e.g. fresh from a bakery, no preservatives vs. prepackaged with preservatives) affect the results?

What is the purpose of Glucose test? For Carbohydrates Metabolism : of Glucose during lab?

in the SIM test, the S part checks for: fermentation of sugar fermentation of sulfur synthesis of ferric citrate reduction of sulfur reduction of sugar

You are given a mixed culture of 3 bacteria–Methicillin-resistant Staphylococcus aureus(MRSA), Escherichia coli and Enterobacter aerogenes. Assume that Escherichia coli can ferment glucose, maltose, sucrose and lactose and also produce carbon dioxide gas on fermenting these. Assume that Enterobacter aerogenescan ferment only sucrose and cannot ferment glucose, maltoseand lactose. Also on fermenting sucrose it produces hydrogen sulphide gas. Assume that MRSA does not ferment any of these 4 sugarsbut forms endosporesand is sensitive to penicillin. Also they all give similar looking white-colored colonieson an agar plate. Question:Generate pure cultures of these 3 bacteria using the following tools that you learned in the lab. Use any (some or all)of these toolsto generate pure cultures as well as confirm them. A) Any of Staining methods B) Special media plates(McConkey Agar or Blood Agar or Mannitol Agar plates) C) Fermentation media tubes(Triple Sugar Iron (TSI)or Durham tubes) D) Any…
