Identifying the Unknown Bacteria: Bacillus cereus Brittany Moy Coastline Community College Abstract Bacillus cereus is a Gram-positive‚ facultative aerobic‚ spore-forming‚ rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria

CHAPTER 1 INTRODUCTION 1.1 PRELIMINERIES Due to highly development of chemical and biochemical industries‚ acetic acid has largely produced to fulfil the needs of world demand in production of daily used products and for pharmaceutical needs. Therefore‚ this study is carried out to introduce the production of acetic acid using biological pathways which includes the used of microorganisms. In this chapter will briefly explained on the knowledge about acetic acid and the microorganism

Systematic Identification of Bacillus subtilis and Serratia marcescens Through a Battery of Tests and Plates Introduction: The purpose of this experiment was to use a systematic battery of tube tests and plates designed to lead to identification of two unknown bacterial species‚ from the combination of all results. A sample of bacteria was used‚ labeled “Sample 4”‚ from which both species was to be obtained‚ one gram positive and one gram negative. Table 1 is a list of the possible bacteria to

In this experiment six antibiotics will be tested to determine which is the most effective on gram-negative bacterium Escherichia Coli and gram-positive bacterium Bacillus Cereus. In previous class experiments‚ gram-staining was conducted to determine the qualities of gram-positive

will gain drought tolerance as well. Not only can genes be transferred from one plant to another‚ but genes from non-plant organisms also can be used. The best known example of this is the use of B.t. genes in corn and other crops. B.t.‚ or Bacillus thuringiensis‚ is a naturally occurring bacterium that produces crystal proteins that are lethal to insect larvae. B.t. crystal protein genes have been transferred into corn‚ enabling the corn to produce its own pesticides against insects such as the European

One good example is the use of Bacillus Thuringiensis‚ commonly known as Bt. Bacillus Thuringiensis‚ is a bacterium that dwells in soil. It acts as a reservoir “of cry toxins and cry genes for production of biological insecticides and insect-resistant genetically modified crops.” How has gene technology benefited
