nitrate bacterium
Definition
Noun A type of nitrobacterium that performs the specific biochemical process of oxidizing nitrites, converting them into nitrates. This bacterium is a key agent in the later stage of the nitrogen cycle.
Usage
The term "nitrate bacterium" is used specifically in the contexts of microbiology, ecology, and soil science to refer to these nitrifying microorganisms. * The presence of nitrate bacteria in the soil is essential for plant nutrition. * Researchers studied the activity of the nitrate bacterium under different pH conditions.
Advanced Usage
- Scientific Classification: In technical literature, these bacteria are often referred to by their genus names, such as .
- The experiment confirmed that Nitrobacter, a classic nitrate bacterium, was responsible for the conversion.
Variants and Related Words
- Nitrobacterium (n): The broader category of bacteria involved in nitrification, which includes both ammonia-oxidizing and nitrite-oxidizing types.
- Nitrifier (n): A general term for any microorganism that carries out nitrification.
Synonyms
- Nitrite-oxidizing bacterium
- Nitrobacter (when referring to the specific genus)
Related Phrases
- Nitrification process: The two-step biological process where ammonia is converted to nitrites and then to nitrates. Nitrate bacteria are responsible for the second step.
- The nitrate bacterium completes the nitrification process.
Noun
-
any of the nitrobacteria that oxidize nitrites into nitrates
