physiological class of bacteria capable of utilising agar as a sole carbon source. This ability is made available by the use of agarases - enzymes which break down agarose into oligosaccharides. This physiological class branches through genii‚ regardless of Gram Stain status or morphology. Through a review of scientific literature we can find identification methods‚ optimum conditions and the general function and location of agarolytic bacteria‚ as well as methods to culture them in vitro for study and experimentation

LECTURE 2 GRAM STAIN Developed by a Danish called Christian Gram in 1884 Stain a heat-fixed smear with a dye like crystal violet and fix with Iodine Then wash with ethanol or acetone Finally counterstain with a dye of different colour such as safranin (what is its colour? You have used it before!) 2 5 Gram positive Gram negative

Introduction: Our project is made from the raw materials such as starch‚ alum and annatto seeds. One of our reasons in making this project is it can help students save money because our product can be a substitute for glue. It doesn’t cost us too much time because we can make this in a short period of time. IV. Review of Related Literature:

Careers PCT 1 October 14‚ 2012 Clostridium Difficile Clostridium difficile is a gram positive‚ spore forming anaerobic bacillus‚ which may or may not carry the genes for toxin A-B production. These two types of protein exotoxins produced by the Clostridium difficile bacillus‚ toxin A and toxin B‚ can have an infectious form and a non-active‚ non-infectious form. The disease spreads throughThe spores can survive for a longer period of time in the environment and are not infectious

DIPTHERIA Diphtheria is an infectious disease caused by the bacterium corynebacterium diphtheria. This disease affects the mucous membranes of the respiratory tract and can also affect the skin (cutaneous diphtheria)‚ including the lining tissues in the ear‚ eye‚ and genital areas. Diphtheria was discovered in the 1880s‚ it was the leading cause of children’s death in many parts of the world‚ it was also known as “The Strangling Angel of Children”. Although diphtheria affects younger children

included: Gram stain‚ mannitol salt agar‚ coagulase tube test‚ and an antimicrobial susceptibility test. The tests selected were based on the results of a gram stain. Gram staining‚ the most commonly used differential stain‚ allows for the fast and easy detection between gram negative and gram positive organisms based on the presence or absence of peptidoglycan. A gram positive organism resists the decolorization process due to a large amount of peptidoglycan and appears a purple color. A gram negative
