Unknown Lab Report #1 Unknown #1 April 25‚ 2012 Microbiology Spring 2012 MCB2010C Unknown #1 Introduction Identity of a microorganism has proven to be very significant. Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

The 4 different types of Microbes Organisms that cause disease are known as pathogens. The 4 different types of microbes than can cause disease are; Bacteria Bacteria‚ also known as Bacterium in the singular term‚ are a prokaryote. Prokaryotes are simple ‚ single celled organisms. Bacteria get their nutrients from the environments in which they live‚ in some cases‚ that is the human body. http://kidshealth.org/kid/talk/qa/germs.html They are larger than viruses‚ but smaller than human body

Wave Nature of Light Objective: The purpose of this lab is to investigate interference‚ otherwise known as the diffraction of light. A beam of light acts a wave‚ and we are able to use equations so calculate the wavelength of the light used. The diffraction of a straight edge demonstrates that light waves bend around straight edges‚ allowing light to enter an area of shadow. When waves are superposed‚ they reinforce each other when crests are in phase and cancel out when they are not in phase

PEES 4200W- Physiology of Exercise Lab #2: Metabolism and Energy Expenditure 1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry‚ how efficient the subject ’s body is at utilizing the oxygen inhaled‚ as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min‚ the volume

LSM1102 Lab Report Introduction Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin)

HYDRO-ECOSPHERE Hydro-ecosphere is considered as a more suitable habitat for microorganisms than the atmosphere and lithosphere‚ mainly because hydrosphere contains water‚ which is important in microbial metabolism (Atlas and Bartha‚ 1993). The unique properties of water are also attributes of hydrosphere as a suitable habitat. Due to polarity of water (slightly negative and slightly positive)‚ water is considered as a great solvent‚ capable of forming hydrogen bonding. Large heat

side were far less than the amount of bacteria on my constant side. In my case‚ quantitative data can be used to support it even further as it proves that the amount of bacteria on my unaltered‚ control side of the petri dish was much more than the changed‚ experimental side of the petri dish. You could also argue that qualitative data could help support it because you can visually see the difference that the Hand Sanitizer made in killing the bacteria. Unfortunately‚ since I did not do the experiment

needed to sustain the acute infectious diseases. So descendants of the hunter-gatherers who crossed from Siberia were familiar with the ancient persistent microbes we all inherited from our ape-like ancestors. The reason for the absence of crowd disease microbes in the Americas is probably quite straightforward; in the Old World these microbes

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast
