a media plate cultured with an unknown species of bacteria. I was then instructed by my professor to use all of my previous knowledge to identify the unknown bacterial pathogen. This lab led me to master my skills of using the Gram stain‚ testing for catalase‚ testing for coagulase and using the oxacillin screen. Now I am going to take you with me on the journey to the unknown. As I recall from earlier that semester‚ the first test that needed to be performed was the Gram stain. The Gram stain

Email: femijohn@gmail.com 43 INTRODUCTION The roles of metal ions in metalloenzymes include direct participation in catalysis‚ stabilization of protein structure and regulation of enzymatic activity. Membrane alkaline phosphatase (ALP) is a metal-containing enzyme that serves as a good model for the study of metal ion interactions in enzyme catalysis. Native E. coli ALP contains three

Bacterial growth is the division of one bacterium into two daughter cells in a process called binary fission. Providing no mutational event occurs the resulting daughter cells are genetically identical to the original cell. Hence‚ "local doubling" of the bacterial population occurs. Both daughter cells from the division do not necessarily survive. However‚ if the number surviving exceeds unity on average‚ the bacterial population undergoes exponential growth. The measurement of an exponential bacterial

Procedures for Part A: For Activity A‚ we first tested enzyme activity. First‚ we used an H2O2 syringe to transfer 10 mL of H2O2 into an unlabeled 60-mL cup. Then‚ we used a transfer pipet to add one mL of catalase solution into the unlabeled 60-mL cup that we put H2O2 in. After that‚ we observed the solution for one minute. Then we tested the effect of boiling on enzyme activity. First we used a transfer pipet to transfer 4 mL of catalase into a test tube. After that‚ we placed the test tube filled

Do you think being asleep at 10 p.m. is normal? “No!”‚ is what most teenagers would say because that time is ridiculously early. Most high school and middle school students regularly finish up work late at night because they don’t have time during the day.
