In this experiment, an unknown bacterium was to be identified using a number of different tests using several different bacteria for comparison the unknown was tested with gram staining, spore staining, oxygen requirement tests, catalase test, nitrate test, differential media test, motility test, triple sugar iron test, carbohydrate.

The oxidase test is used to identify bacteria that produce cytochrome c oxidase, an enzyme of the bacterial electron transport chain when present, the cytochrome c oxidase oxidizes the reagent (tetramethyl-p-phenylenediamine) to (indophenols) purple color end product. And antibiotic resistance in a controlled experiment • use the heat shock method of -pglo pre-lab questions label one closed micro test tube +pglo and. Examples of antibiotic sensitivity testing methods volumes at about 10 ml in standard test tubes for resistance to each of twelve different antibiotics. The lab techniques and procedures used throughout this experiment were from mcdonald's laboratory manual (4) to start, the two unknown bacteria had to be successfully isolated using a wire loop, a small sample of the numbered test tube was plated on a nutrient agar using the quadrant streak method (4. This is a positive result for the citrate test when simmons citrate agar is inoculated with escherichia coli , the medium remains green this is a negative result for the citrate test.

The south carolinian physician j marion sims, often referred to as the father of gynecology, developed a surgery for complications of childbirth on slave women in the 1840s (long seen as a villain, more recent historical research has suggested that some women willingly participated in sims' surgeries, making him a more ambiguous figure. The limiting step in the identification of a bacterium using the um resides in the detection step (stage i) the um solved this limitation by providing an array of primer mixtures (table 5 a, b) according to the um, golden mixtures g7 and g5 can potentially produce 12 different primer pairs (or pcr amplicons.
