The extent of disruption depends on the applied pressure and the number of passes through the homogenizer chamber and can be described by the equation, ln(1 − ?) = −????. Is Bacillis brevis a gram-positive or gram-negative bacterial cell? Based on this response, describe the cell wall structure and how it differs from the other type. Develop an equation for calculation of pressure as a function of the number of passes through the homogenizer. What factor(s) did you take into consideration when selecting the number of passes? Escherichia coli cells are lysed with the same homogenization, is this organism gram-positive or gram-negative? What impact does increasing the value of the constant, a, have on the required number of passes at a given pressure? What factors impact the value of a? If fine cell debris after homogenization makes subsequent solid-liquid separation difficult, what would you recommend? Answer as…arrow_forward
