- Create an experimental flow chart for the extraction of glucose-1-phosphate from starch.arrow_forwardYou are given a mixed culture of 3 bacteria with following characteristics- 1) Bacteria 1 - Methicillin- resistant Staphylococcus aureus (MRSA) (does not ferment any of these 4 sugars but forms endospores and is sensitive to penicillin) 2) Bacteria 2 - Escherichia coli (can ferment glucose, maltose, sucrose and lactose) and also produce carbon dioxide gas on fermenting these 3) Bacteria 3 - Enterobacter aerogenes. (can ferment only sucrose and cannot ferment glucose, maltose and lactose. Also on fermenting sucrose it produces hydrogen sulphide gas.) Also they all give similar looking white-colored colonies on an agar plate. Question: Generate separate pure cultures of these 3 bacteria from the mixed culture using the following tools that you learned in the lab. Use any (some or all) of these tools to generate pure cultures as well as confirm them. Any other technique that you use should be one you learned in lab.

- Yeast cells are added to a 3.0 L batch bioreactor so that the initial cell concentration is [X]. = 1.3 g cells / L. The growth mediğim in the reactor, which is well-mixed so the cells have access to all nutrients, contains 150 g CELL DATA ribose (C5H10O5, MW 150), 75 g ammonia (NH3, MW 17), and 85 g oxygen (O2, MW 32).

- In this lab, we used three different bacteria (E.Coli, B. Subtilis, and A. Faecalis) in fermentation assays to determine their ability to ferment three different carbohydrates: lactose, glucose and sucrose.

This figure shows how the pH in the Methyl Red and Voges-Proskauer (MR-VP) broth changes during incubation from time zero to 48 hours with a VP-positive bacteria species. VP-positive bacteria initially produce lactic acid and temporarily lower the pH, but the lowered pH activates the 2,3-butanediol fermentation pathway. Accumulation of its neutral end products such as acetoin and 2,3-butanediol raises the pH by the end of the incubation time. The acetoin that accumulates in the broth also reacts with the reagents added after incubation to produce a red color. If the reagents were added and the results were recorded early, at 24 hours rather than at the full incubation time at 48 hours, would the color result for the VP (+) bacteria be the same at 24 hours than at 48 hours? If different, explain how the color result is different. What chemical…arrow_forward
