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 Dangers of Genetically Modified Organisms In 1980‚ the first GMO patent was issued through a U.S. Supreme Court ruling. A mere thirty-five years later this fairly new discovery is readily available in an over-abundance to consumers for consumption. Genetically Modified Organisms have been developed because they do not follow the natural laws of crop production. They have been engineered for herbicide tolerance and rapid growth among other purposes. The Food and Drug Administration has stated

The purpose of life is a life of purpose Throughout my life‚ I have persevered through much pain and misfortune; however‚ instead of using my experiences as reasons for a life of retribution and reparations‚ I used these tragedies as motivation to making other people’s lives better. Growing up I witnessed my grandmother assist anybody she saw struggling or needed help. During the 17 years she was a part of my life‚ I watched her nurse back to health approximately 300 foster children‚ because

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

All organisms must have adaptations to survive. The adaptations that organisms develop help them to survive in their environments and then are passed down through reproduction. The genes are passed to future generations and adaptations continue to occur over long periods of time. Nature Works tells us‚” animals that are better adapted to their environment survive and breed. Animals that are not well adapted to an environment may not survive.” There are three types of adaptations that can occur: morphological

MIC 230 Unknown Identification Report The objective of this experiment was to identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully

Short Essay 2: Genetically Modified Organism Debate A genetically modified organism is used to refer an organism whose genetic material has been changed by genetic engineering techniques‚ which cut and combine DNA molecules from different organism into one molecule (Wikipedia‚ 2012). This way‚ scientists can give it new characteristics that people desire but do not have normally. Since the benefits brought by genetically modified organism are extremely obviously‚ such as lower

Amongst many problems that living organisms face‚ one of the biggest is the change in the temperature of the environment. Why is this a major problem for living organisms? A change in the temperature of the environment disrupts many of the body’s enzymes and regulatory proteins‚ changing their shape and perturbing their function. However‚ organisms have taken two different approaches to tackling this problem we call this organisms endotherms and ectotherms but in this essay‚ we will talk about an
