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.
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 ...
[1] [2] This process is called saprotrophic nutrition. Fungi are examples of saprobiontic organisms, which are a type of decomposer. [citation needed] Saprobiontic organisms feed off dead and/or decaying biological materials.
Fungi are the primary decomposers in most environments, illustrated here Mycena interrupta.. Saprophages are organisms that obtain nutrients by consuming decomposing dead plant or animal biomass. [1]
The larger snail is L. stagnalis with saprobic value 2.0; the smaller one is possibly a Physa fontinalis with a value of 2.4.. The saprobic system is a tool to measure water quality, and specifically it deals with the capacity of a water body to self-regulate and degrade organic matter.

Instead, these other decomposers live by absorbing and metabolizing on a molecular scale (saprotrophic nutrition). The terms detritivore and decomposer are often used interchangeably, but they describe different organisms. Detritivores are usually arthropods and help in the process of remineralization. Detritivores perform the first stage of ...
Aspergillus niger is a prime example of this; it can be found growing on damp walls, as a major component of mildew. [citation needed] Several species of Aspergillus, including A. niger and A. fumigatus, will readily colonise buildings, [7] favouring warm and damp or humid areas such as bathrooms and around window frames.
