DISCUSSIONIn the first part of the lab‚ since the effect of moist heat treatment on bacterial spores wasbeing investigated‚ the spores from Bacillus stearothermophilus was used. Using the three testtubes with spores‚ the first one (1) was autoclaved‚ the second (2) was boiled‚ and third (3)received no treatment. The fourth test tube (4) didn’t have a spore strip and served as a controlfor the effectiveness of the aseptic pipetting technique. As hypothesized‚ test tubes 1 and 4experienced no bacterial

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

Coccus is a term used to describe a type of morphology that helps us distinguish different kinds of bacteria. The cell’s morphology is only one of the many ways we can differentiate the different species. Looking at these bacterium underneath the microscope is an important step to determine which kind of species it is. All cocci bacteria are not gram positive‚ but this lab will examine only this kind because of their influence in human health. Staphylococcus Aureus is a gram-positive coccus bacterium

The graph was interesting as the results were not expected. Morning fresh which costs the most was expected to have the largest zone of inhibition but this was not the case. Palmolive has the largest zone of inhibition having an 0.8 cm larger diameter then morning fresh had. It was expected that ultra would have the smallest zone of inhibition as it was the cheapest. The sponges results were also interesting as there was no clearly seen zone of inhibitions that were noticeable enough to be able

The effect of environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH on microbial growth and survival Abstract: Microbial growth can be affected by different environmental factors such as temperature‚ osmotic pressure‚ oxygen concentration and pH. Six experiments were carried out in this report testing for microbial growth against different environmental factors. Good aseptic techniques were used to prevent contamination‚ resulting in a uniform set of results

Honestly‚ can they be anymore clingy? Really were the Michael Jordan’s of the element world. Todays the day I leave my home in the Tundra Biome‚ finally graduated from the periodic table and am on my way to the Tropics.
