  2. Clostridium tetani - Wikipedia

    en.wikipedia.org/wiki/Clostridium_tetani

    Clostridium tetani is a common soil bacterium and the causative agent of tetanus.Vegetative cells of Clostridium tetani are usually rod-shaped and up to 2.5 μm long, but they become enlarged and tennis racket- or drumstick-shaped when forming spores.

  3. Soil microbiology - Wikipedia

    en.wikipedia.org/wiki/Soil_Microbiology

    Some bacteria can colonize minerals in the soil and help influence weathering and the breaking down of these minerals. The overall composition of the soil can determine the amount of bacteria growing in the soil. The more minerals that are found in area can result in a higher abundance of bacteria.

  4. List of mineral tests - Wikipedia

    en.wikipedia.org/wiki/List_of_mineral_tests

    The Mohs Hardness Scale is the main scale to measure mineral hardness. Finger nail is 2.5, copper coin is 3.5, glass is 5.5 and steel is 6.5. Hardness scale is Talc is 1, Gypsum is 2, Calcite is 3, Fluorite is 4, Apatite is 5, Orthoclase Feldspar is 6, Quartz is 7, Topaz is 8, Corundum is 9 and Diamond is 10. Odor; Not always recommended.

  5. Clostridia - Wikipedia

    en.wikipedia.org/wiki/Clostridia

    Clostridia can be diagnosed by recognizing the characteristics of the lesion of the infection along with Gram stains of the tissue and bacterial culture. [1] Although the body does not have adequate defenses alone, this microbe can be controlled with the help of antibiotics, like penicillin, and tissue debridement for the more severe cases.

  6. Soil biology - Wikipedia

    en.wikipedia.org/wiki/Soil_biology

    Bacteria live in soil water, including the film of moisture surrounding soil particles, and some are able to swim by means of flagella. The majority of the beneficial soil-dwelling bacteria need oxygen (and are thus termed aerobic bacteria), whilst those that do not require air are referred to as anaerobic , and tend to cause putrefaction of ...

  7. Colonial morphology - Wikipedia

    en.wikipedia.org/wiki/Colonial_morphology

    Examining colonial morphology is the first step in the identification of an unknown microbe. The systematic assessment of the colonies' appearance, focusing on aspects like size, shape, colour, opacity, and consistency, provides clues to the identity of the organism, allowing microbiologists to select appropriate tests to provide a definitive ...

  8. Bacillus licheniformis - Wikipedia

    en.wikipedia.org/wiki/Bacillus_licheniformis

    Bacillus licheniformis is a bacterium commonly found in the soil. It is found on bird feathers, especially chest and back plumage, and most often in ground-dwelling birds (like sparrows) and aquatic species (like ducks). It is a gram-positive, mesophilic bacterium. Its optimal growth temperature is around 50 °C, though it can survive at much ...

  9. Isolation (microbiology) - Wikipedia

    en.wikipedia.org/wiki/Isolation_(microbiology)

    Bacteria extracted from soil sample. In order to isolate a microbe from a natural, mixed population of living microbes, as present in the environment, for example in water or soil flora, or from living beings with skin flora, oral flora or gut flora, one has to separate it from the mix.
