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.
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 ...
Digestion is accomplished by excretion of digestive enzymes which break down cell tissues, allowing saprobionts to extract the nutrients they need while leaving the indigestible waste. This is called extracellular digestion. This is very important in ecosystems, for the nutrient cycle. [citation needed]
Heterotrophic nutrition means that fungi utilize extracellular sources of organic energy, organic material or organic matter, for their maintenance, growth and reproduction. Energy is derived from the breakdown of the chemical bond between carbon and either carbon or other components of compounds such as a phosphate ion .
Nearly three-quarters of Americans drink coffee every day — and now a new study suggests that brewing it at a certain time of day could percolate some health benefits. Health experts provide ...
Protozoa are chemoorganotrophic protists and have three different ways of acquiring nutrients. The first method of acquiring nutrients is through saprotrophic nutrition. In saprotrophic nutrition, nutrients are obtained from dead organic matter through enzymatic degradation. The second method of acquiring nutrients is through osmotrophic nutrition.
