ตัวกรองผลการค้นหา
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.
microorganism
แปลว่าพืชหรือสัตว์ที่มีขนาดเล็กมาก มองด้วยตาเปล่าไม่เห็น, จุลินทรีย์, จุลชีพ
organism
แปลว่าสิ่งมีชีวิต
