Determining the Unknown Microorganism from a Mixed Culture Mylah Ferland‚ Rivier University MICRO 206‚ March 16th‚ 2016 Introduction: An unknown bacterium experiment‚ this experiment was done to discover what bacterium was in a mixed culture sample. This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by

The unknown carboxylic acid’s melting point was 108°C according to the Mel-Temp machine. The melting point is the temperature at which a solid precipitate changes into its liquid form upon heating. The melting point of benzoic acid‚ the aromatic carboxylic acid was 122°C. Thus‚ the product contained impurities which caused the solid to melt at a lower temperature than the actual temperature. Pure solids typically melt at higher temperatures while impure solids melt at lower temperatures. This is

The purpose of the following study is to determine where the two unknown bacteria acquired in Microbiology lab should be classified in regards to temperature‚ pH level‚ and osmoregularity. It is important to classify bacteria in order to identify them. Identification of bacteria is important because they are not only useful but potentially dangerous as well. The identification of bacteria can lead to breakthroughs in healthcare regarding treatment of old and new diseases alike. Identifying bacteria

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness
