David Kennedy Bio 210 Lab Report 1 10/11/13 Microbial Growth Background Information: This lab was conducted in order to understand basic differences among differential and selective media‚ while recognizing how each media is used to isolate and identify microorganisms (Wistreich‚ 2003). The first microorganism analyzed was Staphylococcus epidermidis. This organism is gram-positive‚ single celled‚ arranged in grape-like clusters‚ and cocci in shape (Bukhari‚ 2004). S. epidermidis is approximately

CATALASE Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen. It is a very important enzyme in reproductive reactions. Likewise‚ catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second. Catalase is a tetramer of four polypeptide chains‚ each over 500 amino acids long. It contains

There are many hospital departments‚ staffed by a wide variety of healthcare professionals‚ with some crossover between departments. For example‚ physiotherapists often work in different departments and doctors often do the same‚ working on a general medical ward as well as an intensive or coronary care unit. Each department tends to be overseen by consultants in that specialty with a team of junior medical staff under them who are also interested in that specialty. Accident and emergency this department
