  2. Decomposition - Wikipedia

    en.wikipedia.org/wiki/Decomposition

    Soil disturbance like tilling increases decomposition by increasing the amount of oxygen in the soil and by exposing new organic matter to soil microbes. [64] The quality and quantity of the material available to decomposers is another major factor that influences the rate of decomposition.

  3. Aspergillus fumigatus - Wikipedia

    en.wikipedia.org/wiki/Aspergillus_fumigatus

    Aspergillus fumigatus, a saprotroph widespread in nature, is typically found in soil and decaying organic matter, such as compost heaps, where it plays an essential role in carbon and nitrogen recycling. [1] Colonies of the fungus produce from conidiophores; thousands of minute grey-green conidia (2–3 μm) which readily become airborne.

  4. Decomposer - Wikipedia

    en.wikipedia.org/wiki/Decomposer

    In terrestrial environments, decomposition happens mainly in or on soil, and decomposers' activities lead to increased soil fertility. [7] The main nutrients plants have to derive from soils are nitrogen, phosphorus, and potassium, and all three have to be available in forms that are accessible to and absorbable by the plants.

  5. Saprotrophic bacteria - Wikipedia

    en.wikipedia.org/wiki/Saprotrophic_bacteria

    Saprotrophic bacteria are bacteria that are typically soil-dwelling and utilize saprotrophic nutrition as their primary energy source. They are often associated with soil fungi that also use saprotrophic nutrition and both are classified as saprotrophs. [1] A saprotroph is a type of decomposer that feeds exclusively on dead and decaying plant ...

  6. Aspergillus flavus - Wikipedia

    en.wikipedia.org/wiki/Aspergillus_flavus

    Aspergillus flavus overwinters in the soil and appears as propagules on decaying matter, either as mycelia or sclerotia. Sclerotia germinate to produce additional hyphae and asexual spores called conidia. These conidia are said to be the primary inoculum for A. flavus. The propagules in the soil, which are now conidia, are dispersed by wind and ...

  7. Microbiology of decomposition - Wikipedia

    en.wikipedia.org/wiki/Microbiology_of_decomposition

    Decomposition fluids entering the soil represent an important influx of organic matter and can also contain a large microbial load of organisms from the body. [8] The area where the majority of the decomposition fluid leaches into the soil is often referred to as a cadaver decomposition island (CDI). [ 9 ]

  8. Detritivore - Wikipedia

    en.wikipedia.org/wiki/Detritivore

    Only fungi produce the enzymes necessary to decompose lignin, a chemically complex substance found in wood. A decaying tree trunk in Canada's boreal forest. Decaying wood fills an important ecological niche, providing habitat and shelter, and returning important nutrients to the soil after undergoing decomposition. Detritivore nutrient cycling ...

  9. Saprotrophic nutrition - Wikipedia

    en.wikipedia.org/wiki/Saprotrophic_nutrition

    Saprotrophic nutrition / s æ p r ə ˈ t r ɒ f ɪ k,-p r oʊ-/ [1] or lysotrophic nutrition [2] [3] is a process of chemoheterotrophic extracellular digestion involved in the processing of decayed (dead or waste) organic matter. It occurs in saprotrophs, and is most often associated with fungi (e.g. Mucor) and with soil bacteria.
