Various word roots relating to decayed matter (detritus, sapro-, lyso-), to eating and nutrition (-vore, -phage, -troph), and to plants or life forms (-phyte, -obe) produce various terms, such as detritivore, detritophage, saprotroph, saprophyte, saprophage, and saprobe; their meanings overlap, although technical distinctions (based on ...
All saprotrophic bacteria are unicellular prokaryotes, and reproduce asexually through binary fission. [2] Variation in the turnover times (the rate at which a nutrient is depleted and replaced in a particular nutrient pool) of the bacteria may be due in part to variation in environmental factors including temperature, soil moisture, soil pH, substrate type and concentration, plant genotype ...
Saprophyte may refer to: Saprotrophs ; organisms, particularly fungi, which obtain nutrients directly from dead organic matter or wastes Myco-heterotrophs ; plants, fungi, or micro-organisms that live on dead or decomposing matter and parasitize fungi, rather than dead organic matter directly.
Saprobionts are organisms that digest their food externally and then absorb the products. [1] [2] This process is called saprotrophic nutrition.Fungi are examples of saprobiontic organisms, which are a type of decomposer.
Extracellular phototropic digestion is a process in which saprobionts feed by secreting enzymes through the cell membrane onto the food. The enzymes catalyze the digestion of the food, i.e., diffusion, transport, osmotrophy or phagocytosis.
Saprotrophs (also called lysotrophs) are chemoheterotrophs that use extracellular digestion in processing decayed organic matter. The process is most often facilitated through the active transport of such materials through endocytosis within the internal mycelium and its constituent hyphae .
Parasitism is a close relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. [1] The entomologist E. O. Wilson characterised parasites as "predators that eat prey in units of less than one". [2]
The genus includes both terricolous and lignicolous species. [5] Most species of Sistotrema are white rotting saprotrophs which often occur on highly decayed wood and on bark of attached, dead branches, but endophytic and ectomycorrhizal nutritional modes also exist in some species.
