Metabolism

แปลว่า(Environmental Engineering) The processes which sustain an organism, including energy production, synthesis of proteins for repair and replication.

Phototroph

แปลว่า(Environmental Engineering) Organisms which obtain energy from light using photooxidation.

Biofilm

แปลว่า(Environmental Engineering) A film of microorganisms attached to a surface, such as that on a trickling filter, rotating biological contactor, or rocks in natural streams.

Secondary treatment

แปลว่า(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.

organism

แปลว่าต้นไม้ หรือสัตว์

Autotrophs

แปลว่า(Environmental Engineering) A group of organisms capable of obtaining carbon for synthesis from inorganic carbon sources such as carbon dioxide and its dissolved species (the carbonates). This group includes plants and algae.

Chlorofluorocarbons

แปลว่า(Environmental Engineering) Synthetic organic compounds used for refrigerants, aerosol propellants (prohibited in the U.S.), and blowing agents in plastic foams. CFCs migrate to the upper atmosphere destroying ozone and increasing global warming. Typical atmospheric residence times are 50 to 200 years.

Thiols

แปลว่า(Environmental Engineering) Organic compounds which contain the "-SH" functional group. Also called mercaptans.

Aerobes

แปลว่า(Environmental Engineering) Organisms which require molecular oxygen as an electron acceptor for energy production. See anaerobes.

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.

Biosynthesis

แปลว่า(Environmental Engineering) Catabolism, the production of new cellular materials from other organic or inorganic chemicals.
