UNKNOWN LAB REPORT UNKNOWN NUMBER 54 Ron Williams 7-28-05 Bio 205 Prof. Curlee Fall 2005 Purpose There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory

Eco-Column Lab Write up Alicia Whiteley Block 4 Abstract: In this research and experiment we were testing whether or not we can maintain a healthy eco-system based off creating one from scratch. We initially went into this experiment confident that we were going to be able to keep our fish alive which was proven wrong mid-way through due to high levels of turbidity and the state of the fish. After collecting all of our data‚ we maintained a healthy terrestrial level and a good PH

the unknown organisms in the mixed culture was limited to bacteria that we had worked with previously in lab. Initially a Gram stain was conducted in order to distinguish the unknown bacterium as a Gram-positive and/or a Gram-negative organism (Lancaster and Bennett‚ 2012; Kellenberger‚ 2001). Based upon the results‚ both Gram-negative and Gram-positive bacteria were observed in the unknown mixed culture (Table 1 and Table 2; Kellenberger‚ 2001). In order to isolate the two different bacteria‚ colonies

microorganisms in our planet‚ bacteria. Bacteria lives everywhere‚ in air‚ hot springs‚ and in our bodies. Some bacteria are harmful and some of them are helpful. Biologists use helpful bacteria in several ways. In my essay‚ I will focus on some uses of bacteria in medicine‚ environment‚ and industrial. Bacteria contains many distinctive characteristics that makes it very important for the environment. It is considered one of the basic decomposers in the environment because bacteria analyzes dead organisms

State the principle of triple beam balance A beam balance measures mass as opposed to weight‚ so the mass you weigh will be the same on the moon as it is on earth. Gravity is taken out of the equation‚ unlike a spring balance that measures weight and would measure an article to be 1/6 of the weight on the moon as it would be on earth using the same spring balance that relied on gravity. The principle is that of moment‚ or turning force/torque)‚ calculated by force x distance. Fundamentally‚

on human samples collected from different body sites. The tests are used to detect and identify any microorganisms capable of causing disease. Knowing of unknown microorganism is important on how this microorganism works and how it is structured‚ means knowing how it can affect humans. The purpose of this study was to identify an unknown bacterium by applying all methods that were previously conducted and learned in the medical microbiology laboratory class. **Materials

procedure called gram stain is used in the identification of bacteria. Bacteria can be gram-positive‚ gram-negative‚ or gram-variable. Most bacteria however‚ are usually gram-positive or gram-negative. Gram-positive and gram-negative bacteria react differently to staining because of the differences in their cell walls. Bacterial cell walls contain a polymer called peptidoglycan. Gram-positive bacteria have more of this polymer than gram-negative bacteria. They are also less complex than gram-negative

Observing Bacteria Kelli Jo Simco Microbiology Due: 2/8/13 Abstract: Microscopes are fragile instruments that must be handle with extreme caution as they can produce high quality results when observing the smallest specimens on earth. A microscope must be properly cleaned before use and storage. The different objectives allow for a range of observations. At the highest objectives‚ the resolution can easily be lost which is why the oil immersion lens is used to minimize refraction. While
