FILAMENTOUS BACTERIA Meaning and
Definition
-
Filamentous bacteria refers to a type of bacteria that possess filament-like structures which extend outward from their main body. These filamentous structures are thin and elongated, giving the bacteria a thread-like appearance. They can be found in various environments such as water bodies, soil, sediments, and even within the human body.
Filamentous bacteria are often considered part of the microbial group known as filamentous microorganisms or filamentous forms, which includes both bacteria and fungi. These bacteria are typically classified under the phylum Cyanobacteria (also known as blue-green algae) or the phylum Chloroflexi. However, filamentous bacteria are not limited to these two phyla and can also be found in other bacterial groups.
The filamentous structures of these bacteria serve important purposes. They can facilitate the attachment of bacteria to surfaces, allowing them to form biofilms or mats. Filamentous bacteria are often found in wastewater treatment plants, where they aid in the breakdown of organic matter by forming tangled mats that enhance biomass retention and create complex microbial communities.
Furthermore, filamentous bacteria can play key roles in nutrient cycling and ecosystem functioning, as they can absorb and fix atmospheric nitrogen, which plants can utilize for growth. Some types of filamentous bacteria are also capable of photosynthesis, utilizing sunlight and converting carbon dioxide into organic compounds.
In summary, filamentous bacteria are bacteria with thread-like structures that extend from their main body. They have various ecological functions, including forming biofilms, aiding in wastewater treatment, nutrient cycling, and even photosynthesis.
Etymology of FILAMENTOUS BACTERIA
The word "filamentous" comes from the late Middle English word "filament", derived from the Latin word "filamentum", which means "thread" or "fiber". It is related to the Latin verb "filare", meaning "to thread". "Filamentous" refers to something composed of or resembling threads or filaments.
In the context of bacteria, "filamentous bacteria" are a type of bacteria whose cells are elongated and interconnected, forming thread-like structures or filaments.
