- what are two differences between agarose gel electrophoresis and SDS PAGE?arrow_forwardFor the study of alanine production by a recombinant strain of E. coli, cultivation was carried out in a benchtop bioreactor with 4.5 L of culture medium, using glucose as a limiting substrate. During the cultivation, there was no lag phase and the cells showed exponential growth for 5 hours. The following table presents the results of the analysis of ammonia and glucose consumption, and alanine accumulation throughout the cultivation. Knowing that 500 mL of a cell suspension at a concentration of 5.0 g/L (inoculum) was added to the 4.5 L of medium in the reactor and that the YX/NH3 previously determined was 7.5, calculate:a) the maximum specific growth rateb) YX/S and YP/S yield factorsc) How long would it take to reach Cx = 30 g/L if the cells continued with the exponential growth profile until the end of the culture (without nutrient deprivation or any type of inhibition)?d) Describe how the mathematical treatment of the data should be done to determine the type of product formation…arrow_forwardThe table below shows the response of our ESKAPE safe relatives to 4 bacteria isolated from a master grid. We do not know the identity or any characteristics of the unknown bacteria. Each safe relative was spread onto a petri dish using aseptic technique. A grid pattern was taped to each plate and the unknown bacteria were patched into one of the squares. If there was no inhibition visible, including with a magnifying lens, the result was listed as -. If there was an inhibition zone between 1 and 10mm in diameter, the result is listed as +. If the inhibition zone was 10mm or greater, the result is listed as ++. In the lab, the MGC instructors plated all 6 of the ESKAPE pathogen safe relatives on LB agar plates. Then we patched Unknown Bacteria 5 from a Master plate onto the safe relative. The results are shown here: METRIC METRIC METRIC 1 B. subtilis S. epidermidis E. coli Complete the final column (Unknown Bacteria 5) of the table by selecting -, +, or ++ using the criteria in the…arrow_forward
