Discussion on unknown bacteria

Microbiology discussion and conclusion section of a microbiology lab report in microbiology class students are asked at the end of the semester to identify unknown bacteria using all the lab techniques they have learned and practiced throughout the semester here is a sample of a section of the final lab. One reason for this prediction is that a primary concern for the cultivation of novel bacteria is the effective throughput rate as discussed above, the number of bacterial taxa that have never been cultured is thought to be considerable except for the cases in which cultivation efforts are directed at specific, preidentified strains. Gram stain discussion: gram staining is a differential procedure, useful in determining whether an unknown bacteria is a gram-positive or gram-negative knowing this type of information allows us to have an idea whether a particular antibiotic would be effective against the microorganism gram staining technique is. Gram negative unknown lab report # 31 biol 3444-007 diana monroe ta: madhab sapkota abstract in this experiment an unknown gram-negative sample was obtained randomly to identify the possible microorganisms using comparative analysis several biochemical tests were performed to determine which bacterium. Unknown results (3) a tentative identification of the isolated bacterium using flow charts (bensen 1990), and bergey's manual of systemic bacteriology (volumes i–iv) and (4) a conclusion discussing the basis on which the unknown was tentatively identified exercise a: isolation of an unknown bacterium from soil.

The final project: isolation and identification of one unknown bacteria a lab practical each student will receive a tsa slant containing two bacteria each student is responsible for streaking the bacteria for isolation on the provided tsa plate and for conducting a variety of tests to describe the biological properties of one. Unknown, it is customary to write, a trypticase soy agar (tsa) plate was used to isolate the unknown it is also microbiology laboratory class for the identification of an unknown bacterium materials and example of a discussion: after several differential tests, it was concluded that unknown g was escherichia coli. We discuss current genotypic and proteomics technologies for bacterial identification and characterization, and present an overview of how these new the unknown bacterium will be identified either by comparing the resulting mass spectra with a collective proteomics database containing mass spectra. The methods that were previously studied and practiced in the microbiology laboratory class were applied in order to identity two unknown bacterium matrials and methods the lab instructor gave out a test tube labeled number 118, which consisted of two unknown bacteria, one gram negative and.

In this exercise, you will draw upon many of your new skills to identify unknown bacteria you will be given three bacterial cultures and asked to identify each to the level of genus the organisms selected include types you have studied this semester and some new genera figure 1 presents a flow chart for identifying the. The result was that it was a gram negative bacteria this particular bacteria was also a cocci the fact that this bacteria grew on an emb plate provided further support that it was a gram negative bacteria we then proceeded to perform a battery of biochemical tests on this unknown the tests performed on this bacteria. Biology 225 sections of the report title introduction materials and methods results discussion conclusions references title purpose: to accurately describe the scope of your project be descriptive include your tube # example: the identification of two unknown species of bacteria in tube #99.

Abstract: the aim of this study isolation, characterization and molecular identification of unknown bacteria from the outlet of sewage treatment salmonella sp is a gram negative, rode shaped bacteria which forms white raised irregular colony the sequence 3 results and discussion the traditional. This approach lacks molecular techniques such as sequencing of genes encoding 16s rrna, which is currently the method of choice for identification of unknown bacteria a laboratory activity was developed to teach students how to identify microorganisms using 16s rrna polymerase chain reaction.

Discussion on unknown bacteria

Almost every known antibiotic came from 1 per cent of bacteria now we are learning how to grow the unknown microbes, and who knows what riches we'll discover.

  • Discussion viruses are infectious agents with both living and non-living characteristics 1 living characteristics of viruses a they reproduce at a fantastic rate, but only in living host cells b known bacteriophages are used to identify unknown bacteria by observing whether or not the bacteria are lysed this is called.
  • Discussion/conclusion after several different biochemical tests, it was concluded that the gram positive in unknown 120 was staphylococcus aureus the bacterium was grown on a tsa agar plate for use of additional tests, gram stain reaction determined that the unknown was a gram positive cocci.
  • The different tests performed on the bacteria were all done in order to determine the identity if an unknown bacteria discussion: determining the unknown was somewhat of a challenge because all of my tests turned out incorrectly however, i did determine the shape and motility correctly as well as gram staining and.

Interpret the results of all of the media and/or tests that you conduct explain in detail what the results indicate about the cell wall structure and metabolism of your unknown also discuss the evidence for or against your bacteria being a possible pathogen always record the dates of your inoculations and observations. Presentation on theme: lab 8&9 goals and objectives : exercise 37: morphological study of unknown bacterium exercise 38: cultural characteristics discuss observations of the— presentation transcript: 1 lab 8&9 goals and objectives : exercise 37: morphological study of unknown bacterium exercise 38: cultural. After running these tests, it was deduced that the two unknown bacteria could be identified as staphylococcus aureus and klebsiella pneumonia discussion the results obtained were thought to be true after the first gram staining test was done on each bacterium this determination was made based on. Away from the inoculation point, and tested negative for indole production because there was no color change upon the addition of kovac's reagent (3) all of these results are summarized in table 1 vi discussion the bcp broth tests the ability of an organism to ferment carbohydrates organisms that.
