MICROBIOLOGY 3444-007 Gram Negative Unknown Unknown Bacteria #14 LeNaiya Kydd 4/2/2014 Abstract In order to be able to identify the unknown organism that was given to us‚ we had to conduct a number of different tests. These biological tests are used because they help us be able to identify the properties of the unknown we have and be able to compare our observed results with actual results of all the potential organisms. When all of the data of the test are put together it is easy to

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

In a brief essay‚ identify at least two of the implications implicit in the society reflected in the poem. Support your statements by specific references to the poem. The Unknown Citizen Comment [ANn1]: OK‚ so I need to IDENTIFY two implications implicit in the society. I need to make sure I’m speaking only to the society reflected IN the poem. I’ll make sure to quote the poem itself. by W. H. Auden (To JS/07 M 378 This Marble Monument Is Erected by the State) He was found by the

Discussion The possible identity of 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

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‚

other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However‚ because new strains continue to emerge‚ it is of the utmost importance that microbiologists and microbiology students understand the nature of each bacterial

Identifying Unknown Bacteria Using Biochemical and Molecular Methods Beginning of Instructor Pages Instructor Pages - - 3 Purpose The purpose of this lab is to introduce a variety of lab techniques to students working on the common problem of identifying an unknown bacterium. This lab helps students develop an understanding of the biochemical and molecular differences in bacteria and introduces the concept of identifying species based on characeristic gene sequences. Students work through

distinguishable structures‚ and reaction to Gram stain is a good start in identifying bacteria. Other staining techniques such as Acid Fast stain are also useful in determining species. More important in identification of a genus and species of bacteria are biological tests‚ including the determination of the types of nutrients a cell can use‚ the products of its metabolism‚ and the response to specific chemicals. Other factors that can assist in identification of bacteria are their ecological habitats
