Nitrogen fixation

แปลว่า(Environmental Engineering) The conversion of atmospheric (or dissolved) nitrogen gas into nitrate by microorganisms.

Ecology

แปลว่า(Environmental Engineering) The study of living organisms and their environment or habitat.

Anaerobes

แปลว่า(Environmental Engineering) A group of organisms that do not require molecular oxygen. These organisms, as well as all known life forms, require oxygen. These organisms obtain their oxygen from inorganic ions such as nitrate or sulfate or from protein.

Disease

แปลว่า(Environmental Engineering) Any impairment of the normal function of an organism.

Autotrophic

แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon for synthesis of protoplasm. Ecologists narrow the definition further by requiring that autotrophs obtain their energy from the sun. In microbiologist parlance, this would be a photoautotroph. See photoautotrophic and chemoautotrophic.

Suspended growth reactor

แปลว่า(Environmental Engineering) A reactor in which the microorganisms are suspended in the wastewater. Examples of suspended growth reactors are activated sludge reactors and anaerobic digesters. See attached growth reactor.

Photoautotrophic

แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon dioxide for protoplasm synthesis and light for an energy source. See autotrophic and chemoautotrophic.

Infectious disease

แปลว่า(Environmental Engineering) A disease caused by pathogenic organisms.

Virus

แปลว่า(Environmental Engineering) A submicroscopic genetic constituent which can alternate between two distinct phases. As a virus particle, or virion, it is DNA or RNA enveloped in an organic capsule. As an intracellular virus, it is viral DNA or RNA inserted into the host organisms DNA or RNA.

Chemoautotrophic

แปลว่า(Environmental Engineering) Organisms which utilize inorganic carbon (carbon dioxide or carbonates) for synthesis and inorganic chemicals for energy. See autotrophic and photoautotrophic.

แปลว่าพืชหรือสัตว์ที่มีขนาดเล็กมาก มองด้วยตาเปล่าไม่เห็น, จุลินทรีย์, จุลชีพ
