Bacteria Lab Report

The most common way of alleviating the specific symptoms arrived from diseases is to ingest antimicrobial drugs. Chemotherapeutical antimicrobial agents are chemical compounds intended to inhibit or kill rapidly dividing microorganisms. In order to derive an antimicrobial drug, different chemical compounds must be synthetically formed. Among these specific chemical compounds is a compound famously known as the antibiotic. The antibiotic is classified as an antimicrobial drug because it’s a chemical that is produced by either a bacterium or fungus, which has the ability to regulate the growth of other microorganisms. The validity of antibiotics as a category of antimicrobial drugs was determined by a method that was developed by Kirby and Bauer, and standardized by the World Health Organization in…

Gram Staining

The Gram stain is a useful stain for identifying and classifying bacteria. The Gram stain is a differential stain that allows you to classify bacteria as either gram positive or gram negative. This gram stain technique was discovered by Hans Christina Gram in 1884. The gram stain procedure separates all bacteria into one of two groups – into gram-negative bacteria which do not stain purple and into gram-positive cells which does stain purple. Bacteria that decolorize easily are called gram-negative, and those that decolorize slowly and retain a primary stain are called gram-positive. The gram staining procedure consists of fixing a colony of bacteria onto a slide and then flooding the colony with various chemicals. First, crystal violet dye was…

Microbiology Laboratory Report

Objectives Aim of this experiment is to differentiate between the two major categories of bacteria , gram positive and gram negative. Through this experiment, gram staining skills develop. More understanding the types and morphology of bacteria. Expected experimental result, Escherichia coli (E.coli ) is a negative gram bacteria which stain pink colour , while Staphylococcus aureus ( S.aureus ) is a positive gram bacteria which stain purple colour. Materials Bacteria : Escherichia coli , Staphylococcus aureus Crystal Violet Gram’s iodine Absolute alcohol Safranin Methodology As per manual. Discussion Gram staining is a very importance preliminary step to differentiate the bacteria into gram positive and gram negative and also enable the bacteria to be examined using a light microscope . Bacteria…

Identifying Bacteria

Bacteria identification is accomplished in a number of ways. Two common tools microbiologists use to identify unknown bacteria include dichotomous key and biochemical tests. The dichotomous key is useful when a microbiologist only needs to know which group an unknown microbe belongs to on a general level. When a microbiologist needs to identify a specific bacterium, biochemical tests are used. PART ONE: GENERAL BACTERIA IDENTIFICATION Review the dichotomous key in Figure A, the bacterial shapes in Figure B, and the Gram stain information below. You will use all three to determine to which major group unknown bacteria belong. Gram Stain Results: Purple = Gram positive Red = Gram negative Neither purple nor red = No cell wall (neither Gram positive…

Review of Related Literature

REVIEW OF RELATED LITERATURE This investigatory project aims to make use of rambutan peeling extracts that is high in phenolic compounds such as tannin and saponin that exhibits antioxidant activity and antibacterial activity against pathogenic bacteria. Although the seeds contain such compounds the peeling exhibit greater amount of the said compounds. Rambutan is a very popular fruit cultivated in the Philippines and it is eaten in large amounts. The rambutans rind is quickly discarded and thrown out after it is cut open and peeled off. The researchers will be maximizing the use of rambutan peelings through this project before they are disposed of. Not only will the researchers maximize the use of the peelings, they would be finding ways to…
