Sampling of Gram-Positive Bacteria and Antibiotic Resistance Resting We thought it would be interesting to find out the different bacteria that grow on things we use on a daily basis and the level of antibiotic resistance that those bacteria have. We chose to swab the toilet seat in the MATC women’s bathroom and the ATM machine in the commons area on campus. We were certain the ATM would be dirtier than the toilet seat since the bathrooms get cleaned every day. The first step we took in testing

Investigation of the probiotic properties of bacterial strains from two probiotic drinks and their survivability in artificial gastric juice ABSTRACT: Two probiotic drinks were investigated in vitro to test their ability to survive acidic conditions and their probiotic factors. Both the products: Actimel and Yakult contain gram-positive bacteria‚ but Actimel also has a gram-negative bacteria. The ability to survive was investigated by adding artificial gastric juice to the products and incubating

Autumn White Biology 258-05 November 26‚ 2012 Unknown #19 Enterbacteriaceae Enterobacter aerogenes ABSTRACT The objective of this report was to identify an unknown microorganism through several differential media tests. Over the course of a couple weeks‚ ten tests were performed. First‚ a gram stain was performed‚ indicating the bacterium was gram negative. An aerotolerance test determined that the bacterium was a facultative anaerobe. Next‚ a negative result in the

In the case of gram-positive bacteria‚ the cell wall is comprised of 60-90% peptidoglycan and is very thick. There are numerous layers of teichoic acid bound with peptidoglycan

Abstract Three tests were performed to determine the identity of unknown number 34‚ a gram stain‚ citrate utilization test‚ and a urease detection test. These tests are explained in detail‚ and the method of performing the tests is described. The tests showed that the bacterium was gram-negative bacilli that did not utilize citrate‚ and the ability to hydrolyze urea using urease. These results indicate that the identity of unknown number 34 is Proteus mirabilis. Introduction Proteus mirabilis is
