Dockendorff Bacteria: Communication Equals Modification Bacteria are organisms that are extremely copious upon this planet. They are tiny and most are single celled organisms that can survive in just about any environment. Anywhere from plants to the human body is where these organisms can be discovered. Some of the strangest places that support bacterial life include places that have extremes of temperature. These bacteria are also very strange‚ much different from bacteria found living in

Jennifer Hauss March 4‚ 2015 Bacterial Transformation Lab Report Introduction In this lab‚ the goal was to transform the bacteria e-coli to glow in the dark (or under a black light). Four plates were set up with agar in them for the bacteria to feed on and grow. Changes were then made to the bacteria. One plate was the control plate‚ having only the LB or agar for the bacteria and negative pGLO‚ which is the liquid not containing the plasmid. This is the plate that was compared with the three others

of a Gram positive coccus genus of bacteria. Several biochemical tests will be performed to aid in the identification of this unknown bacterium. Biochemical tests are a series of tests used to identify certain bacterium The various tests that are used in this lab are the catalase test‚ oxidase test‚ blood hemolytic test‚ MSA‚ blood agar‚ and PEA/ab sens test. A known Gram positive coccus bacteria will be used alongside an isolated Gram positive unknown bacteria for comparison to aid in the ability

The Identification of Two Unknown Species of Bacteria in Tube #72 Introduction: There are many reasons for knowing the identity of microorganisms. The reasons range from 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 class for the identification of an

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

Antibiotic Resistant Bacteria in Hospitals. Introduction Antibiotic resistant bacteria are bacteria who can survive after exposure to one or more antibiotics. Some bacteria present today can even be resistant to multiple antibiotics and these are sometimes referred to by the name Multidrug resistant (MDR). Today many clinically important bacteria are MDR’s and this is a direct result of past decades of antimicrobial use and misuse. If an infection results from this sort of resistant bacteria a stronger antibiotic

Similarities and Differences Bacteria and archaea both share the fact that they are single-celled prokaryotic microorganisms that lack membrane enclosed nuclei. It has been discovered that the two typically can be found to have the same size and shape as one another. “They are both found occurring as rods‚ cocci‚ spirals‚ plates‚ coiled etc.” ("Archaea vs. Bacteria‚" n.d.). Both organisms use the flagella to swim and also reproduce by means of binary fission. On the surface these similarities can

BETWEEN PLASMID AND CHROMOSOMAL DNA IN BACTERIA. Eukaryotes have two or more chromosomes‚ prokaryotes such as bacteria possess a single chromosome composed of double-stranded DNA in a loop. DNA is located in the nucleoid of the cell and is not associated with protein A plasmid is an extra-chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently of the chromosomal DNA. Plasmids usually occur naturally in bacteria. A chromosome is an organized

that a few of the slides he’d been working on had been contaminated by fungus. Upon noting that the staphylococcus colonize bordering the fungus had died he began asking more questions. Namely what was it about the fungus that caused it to kill the bacteria? Through more research he was able to single out a substance that the fungus was producing as the result of its biological processes. He called this substance “mould juice” for

findings: My hypothesis was that garlic decreases the growth of bacteria substantially‚ which my experiment and results have proven to be correct. In order to prove my hypothesis correct‚ I carried out an experiment where I grew bacteria on 14 different agar plates and placed garlic on seven of the agar plates and then had no garlic present in the other seven agar plates. All 14 agar plates were kept under the same conditions while the bacteria colony was growing in order to ensure that all factors were
