test‚ the initially slant for unknown microorganism #17 is important. For this lab‚ two identical slants are used for two reasons. Firstly‚ the slant can be used to make sure that there is no contamination from the Nutrient Agar plate. Secondly‚ the second slant will become a stock culture to prevent the shortage of slants during performing the series of tests. Kliger’s Iron Agar tests can be used to determine multiple characteristics of unknown microorganism #17. Kliger’s Iron Agar slants also contains

Abstract This was an experiment to investigate the amount of respiration by how much carbon dioxide is produced and how using different sugar types affects rate of respiration. The experiment showed that the yeast produces the highest volume of CO2 with glucose. It also showed the yeast respires at its lowest rate with sorbose and maltose was in between the rate of yeast respiration of glucose and maltose. Introduction In this investigation we are going to investigate the amount of respiration

31 October 2011 Identification and observations of Citrobacter Freundii Introduction Citrobacter Freundii is a species of bacteria that can be potentially harmful to humans. It is known to cause meningitis by protruding into the brain and replicating itself (1). The Citrobacter species has also been found as a cause of some urinary tract infections‚ diarrhea‚ and even gastrointestinal diseases and symptoms (3). C. Freundii can be located in a wide variety of soils and water (3). Lastly‚ it is

Some microbes can also be antagonistic or harmful to humans‚ and when scientists isolate them‚ they can study and identify ways on how to counteract the microbes harmful effects. This exercise aims to isolate microorganisms from a variety of environmental samples and to enumerate the different microbial species observed. Methodology Results and Discussion Bacteria‚ molds and yeast have different colony morphologies and characteristics that are specific to

The Population Size of Multiple Microorganisms in Aerobic Compost Alison Pagano‚ Lauren Sammaritano Biology IV- Ecology 4-11-13 Abstract. The experiment provided evidence of microorganisms in aerobic compost. 18 buckets were set up with three different trials of compost‚ wet‚ dry‚ and moist. Although microorganisms were present they were too small to be identified and also conditions in the experiment were not stable enough to maintain life. Due to this we were not able to make

Pathogens are bad microorganisms that cause diseases which make you unwell if gets into your body‚ some of these are bacteria and viruses. Bacteria cause infections like TB‚ legionnaires and flu and viruses cause Hepatitis B‚ measles‚ mumps and more. Bacteria often produce toxins which affect the body‚ while viruses take over whole the cell and then destroy P2 Explain how pathogenic micro-organisms grow and spread? Pathogen microorganisms grow if all right conditions are in place for it to expand

life on the pale blue dot in the vast cosmos. Life seemed pointless when the reality of death constantly loomed. From biology classes I took in high school‚ I learned about microorganisms and there found the answers I had been seeking. The parallels between my life and these organisms were astounding. Although these microorganisms lived relatively short lives and seemed inconsequential they made a huge difference in the vast ecosystems they inhabited: either causing it to flourish or decline.
