Unknown Organism

Lab Report: The Unknown NAME: Donnise Warren end: The draw a bead on of this laboratory announce is for students to be able to bring out an extraterrestrial bacterium given to us by doing a compartmentalisation of lab procedures and biochemical lab test to help identify what detail bacterium we have. INTRODUCTION: There are umpteen reasons for conditioned the identify of microorganisms. Such as knowing the contributive mover of a disease that a patient whitethorn acquire, so that you would know how it could be treated, to knowing which microorganisms could be utilize for devising antibiotics or even food. This lab report was through by implementing methods that have been learned throughout this semester in our microbiology lab ladder which helped identify my unknown bacterium #115. 6/28/2012 The initiative lab procedure performed was the chiliad crisscross. Previously, before jump the universal gravitational constant stain I prepared a bacteria l maculation on a glass slide and utilise the hotness fixing method which was done to help the bacteria cells hold to the glass, kill them, and also helps make the cells easier to stain by coagulating the cells proteins. The gram stain test helped me identify rather my bacterium would be a negative or positive and contumacious the microscopical morphology (shape, and arrangement) of my bacterium as well.

The test results indicated that I had a gram-negative bacterium that were rod shaped and arranged in pairs and some chains. This helped identify my unknown by eliminating such(prenominal) a bighearted class of different bacterium to a more ad hoc categ! ory of bacterium. After I correct my gram stain I set up 3 different media slowness machines. 1) Nutrient Agar(NA), 2) Phenylethyl Alcohol Agar(PEA), and 3) Eosin Methylene grungy Agar(EMB). These mediums go away the nutrients and chemical balances needed to support microbial ingathering and metabolous processes. I set up the NA plate to be used as my increase control, because this type of media supports the growth for almost of the organisms that we culture, the NA plate would also help me to...If you indispensableness to sign a full essay, order it on our website: BestEssayCheap.com
