氨化作用 - 百度百科
氨化作用（ammonification）又叫脱氨作用，微生物分解有机氮化物产生氨的过程。 产生的氨，一部分供微生物或植物同化，一部分被转变成硝酸盐。 很多细菌、真菌和放线菌都能分泌蛋白酶，在细胞外将蛋白质分解为多肽、氨基酸和氨（NH3）。
Ammonification - Definition and Function | Biology Dictionary
2017年4月27日 · The process of ammonification converts organic nitrogen, which is the way nitrogen is contained in compounds in living organisms, into inorganic ammonia (NH 3) or ammonium ions (NH 4 +). Some examples of nitrogen-containing compounds in us and in other living organisms are proteins, nucleic acids like our DNA, vitamins like B-vitamins, and urea.
Ammonification – Definition, Equation, Process, & Diagram
2023年2月17日 · Ammonification is a part of the nitrogen cycle that occurs when microorganisms decompose dead organic matter of plants and animals, releasing fixed nitrogen in the soil, sediment, or water. It is thus crucial for providing living organisms with the source of nitrogen they need for their growth and survival.
Ammonification - an overview | ScienceDirect Topics
Ammonification is the process by which microorganisms present in soil, sediment, or water mineralize low molecular weight, dissolved, organic molecules presenting amine or amide groups (of general formula R-NH2) and produce ammonium (NH 4+).
Ammonification - an overview | ScienceDirect Topics
Ammonification refers to chemical reactions in which amino groups (NH 2) associated with organic forms of nitrogen are converted into ammonia (NH 3) or ammonium (NH 4 +). Ammonium is then available for use in plants as a nutrient, or as a substrate for the nitrification processes.
Ammonification | biology | Britannica
…organic nitrogen into ammonia (ammonification), providing a constant supply of ammonia to be used in the process of nitrification. Although the fixation of atmospheric nitrogen is an essential part of the nitrogen cycle, ammonification and nitrification are the predominant methods by which organic nitrogen is prevented from returning to…
Ammonification – Definition, Stages, Examples and FAQs
2024年1月12日 · Ammonification is the process through which microscopic organisms, such as bacteria or other sorts of decaying creatures, convert compounds containing nitrogen from dead organic matter into simple molecules such as ammonia.
5.2.2: Ammonification - Biology LibreTexts
2024年3月31日 · During ammonification, microorganisms use enzymes to extract amino groups \(\left(\text{NH}_{2}\right)\) of organic nitrogen and convert them to ammonia.
Ammonification: Definition, process, and impact - ScienceQuery
2021年8月13日 · Ammonification is the process of converting nitrogen compounds to ammonia. Nitrogen present in the soil is absorbed by plants and is located in the protoplasm of plant cells through the synthesis of amino acids and proteins.
Ammonification - Ammonification - Nitrogen, Ammonium, …
Ammonification is a particular aspect of the more complex process of organic decay, specifically referring to the microbial conversion of organic-nitrogen into ammonia (NH 3) or ammonium (NH + 4). Ammonification occurs under oxidizing conditions in virtually all ecosystems and is carried out by virtually all microorganisms that are involved in ...
