The Identification of Bacillus Badius [pic] Hannah Melanchuk Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I

However‚ many various inhibitors studied not only blocked the Glucansucrase‚ but also the digestive enzyme amylase in our saliva‚ which is needed to degrade starch. Therefore‚ lots of researches need to be proved

January 1999 B io Factsheet Example glucose fructose galactose Number 39 Carbohydrates: Revision Summary Carbohydrates contain 3 elements: Carbon (C)‚ Hydrogen (H) and Oxygen (O). Thus‚ if we remove water from carbohydrates‚ all that remains is carbon. Carbohydrates can be divided into 3 categories; monosaccharides‚ disaccharides and polysaccharides (Table 1). Table 1. Structure of monosaccharides‚ disaccharides and polysaccharides Category Monosaccharide (made of 1 sugar molecule)

Digestive system 6.1.1 explain why digestion of large food molecules is essential * Large food molecules are polymers‚ broken down into monomers in order to be absorbed into the blood * Humans eat substances by other organsims‚ many which are not suitable for human tissues therefore they must be broken down and reassembled in a form that is suitable * Many molecules in foods are too large to be absorbed by the villi in the small intestine‚ the large molecules have to be broken down

blue-black color indicates that starch is no longer present in the medium. Bacteria which show a clear zone around the growth produce the exoenzyme amylase which cleaves the starch into di- and monosaccharide’s. These simpler sugars can then be transported into the cell to be catabolized. Bacillus species are known to produce the exoenzyme‚ amylase. In our experiment‚ we concluded that Bacillus cereus from soil can hydrolyze starch in order to use these starches as a carbon source and use it. But

Unknown #1 Vomit Serratia marcescens & Bacillus cereus Biol 251 Microbiology 5/14/2009 Introduction The purpose of this study is to differentiate and identify two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The
