The solutions were placed in agar containing Micrococcus Luteus and we observed the amount of bacteria that was lyzed around them. The measurements were taken by observing where the agar cleared around the solutions‚ as the agar was cloudy where bacteria was present. I hypothesized that saliva would

Random errors in experimental measurements are caused by unknown and unpredictable changes in the experiment. Random errors affect the reliability of the data but not the overall outcome of the experiment.· · A random error that occured in the experiment is that only one side of the zone of inhibition

Various forms have been discovered‚ not only to survive‚ but to thrive in the most hostile and extreme of environments and have been named extremophiles and various types of microbes are found in every niche of ecology. Due to their resilience and success at sustaining their existence‚ it has proven to

Understanding the principals of living microbes and identifying my unknown bacteria through numerous biochemical and metabolism tests‚ with the outmost confidence‚ Proteus vulgaris had the precise qualifications. The point of this report is to further explore the identification of my unknown bacteria by revealing the results of the experiments and comparing them to the other six known bacteria: Micrococcus luteus‚ Staphylococcus aureus‚ Staphylococcus epidermidis‚ Alcaligenes faecalis‚ Escherichia

Livja Koka Anaerobic Bacteria In this experiment the purpose is to seek understanding between an organism and its use of oxygen. Oxygen is a very important part of the organisms’ survival. Oxygen has a tendency to form very reactive by-products inside a cell. These by-products create havoc by reacting with protein and DNA‚ thus inactivating them. Cells that are able to live in the presence of oxygen have evolved enzymes to cope with H2O2 and O2- and thus are not inhibited by O2. Also many anaerobes
