Microorganisms are classified according to their structure. By means of flow charts‚ diagrams and tables explain the differences between Viruses‚ Bacteria‚ Cyanobacteria‚ Achaea and Fungi. Bacteria or bacterium are unicellular microorganisms. They are essentially only a few micrometres long and form of various shapes including the spheres‚ rods and spirals.

Procedures were followed as stated in the lab manual and biochemical test handouts. The first procedure that was done was a gram stain followed by a streak of the unknown on a TSA plate in order to determine the gram reaction and observe the colony morphology. After that‚ specific biochemical tests were performed for gram positive‚ since unknown number five was determined to be gram positive rod. The other tests were performed in this order: Mannitol Salt (MSA) streak‚ Blood Agar streak‚ Catalase test

Micro Biology Lab Gram Staining Lab Report Purpose The purpose of this lab was to experiment with a staining technique called Gram Staining. Gram Stains is used to identify and classify bacteria‚ it is a differential stain that allows you to classify bacteria as either gram-positive or gram-negative. The foloowing is a breif summerary of the gram staining procedure. Apply the primary stain Apply Mordant Apply decolorizing agent Apply the secondary stain Bacteria that

Microbes (microorganisms) are minute living things that individually are too small to be seen with the unaided eye the group includes bacteria‚ fungi‚ protozoa‚ and microscopic algae‚ viruses Only minority of microorganisms are pathogenic(disease-producing) 2. What are some of the benefits provided by microbes? Decompose organic waste‚ producers in the ecosystem

C had abundant 2mm growth of pink colonies that are circular and have a mucoid consistency. Microbes C are gram-negative rods bacilli. D had abundant growth of 2mm yellow colonies that are circular and have a mucoid consistency. Microbes D are gram-negative bacilli that gave off a fishy smell. Swarming was
