Lab Section I was present and performed this exercise (initials) The Effect of Osmotic Pressure on Microbial Growth OBSERVATIONS AND INTERPRETATIONS 1 For each species, record a “3” for the salt concentration(s) with maximum growth and “0” for no growth. Use “1” and “2” for intermediate amounts of growth. Organism Control #9 Escherichia coli #21 Staphylococcus epidermidis 5% NaCl Concentration 10% 300 3 3 3 15% DATA SHEET 2-10 20% QUESTIONS 1 Circle the optimum salinity for each organism. Place brackets around the range. Is there any overlap between species? Describe any examples.
The Correct Answer and Explanation is :
