In this lab we used a solution of lactase to test the chemical and physiological properties of this particular enzyme and determined whether the lactase came from human cells or bacterial cells. In the statistical analysis statistical formulas and techniques are used to analyze the significance of a set of data and the validity of the conclusions made based on that data. These are some terms and definitions that will be crucial to understanding the validity of this experiment. An enzyme is a protein

its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress in future work.

– In this method‚ the team will get sample to be tested for E. coli or Escherichia coli and Staphylococcus aureus. E. Coli normally lives in the intestines‚ where it helps the body break down and digest the food you eat. Unfortunately‚ certain types (called strains) of E. Cole can get from the intestines into the blood. This is a rare illness‚ but it can cause a very serious infection. Staphylococcus aureus a bacteria capable of food poisoning. This is often caused by improper food handling‚ which
