layer of materials created by microorganisms on an underwater surface.
Multilayer bacterial populations embedded in a polysaccharide matrix that is attached to some surface (plastic, mucosal membrane) (Lecture: The Bacterial Cell: Structure, Function, Growth, and Gene Regulation II, 1/29/02)
An accumulation in water pipes which may harbour microorganisms.
A film of microorganisms attached to a surface, such as that on a trickling filter, rotating biological contactor, or rocks in natural streams.
a slippery coating of microorganisms that can develop in poorly sanitized pools and spas.
A slimy matrix produced and inhabited by bacteria which enables the bacteria to adhere to a surface and carry out certain biochemical processes essential to the Nitrogen Cycle. In open aquatic environments, biofilm supports a microscopic community of various species of bacteria including nitrifying bacteria, algae, protozoa, and microscopic invertebrates. In the aquarium, biofilm covers all surfaces exposed to water, and tends to build up in the dark, undisturbed areas such as the filter intake tube and other filter parts.
a bacteria-generated slimy layer of material
a collection of microbial communities enclosed by a matrix of extracellular polymeric substance (EPS) and separated by a network of open water channels
a community of microbes, embedded in an organic polymer matrix, adhering to a surface
a community of microorganisms attached to a solid surface
a community of organisms, such as bacteria, that is attached to a surface
a complex aggregation of microorganisms growing on a solid substrate
a complex layer of bacterial cells
a film made of bacteria, such as Thiobacilli or other microorganisms, that forms on a material when conditions are right
a functional consortium of microorganisms organised within an extensive exopolymer matrix
a group of organisms that have attached to a surface and entombed themselves in an impenetrable polysaccharide (sugar) coating
a layer of bacterial cells held together on a solid surface that can be either living (e
a layer of microorganism contained in a matrix that may form a thin layer of slime on surfaces in contact with water
a layer of microorganisms contained in a matrix (slime layer), which forms on surfaces in contact with water
a layer of organic slime made of microscopic larvae, bacteria, and other assorted bioinvasive organisms
a microbial mass composed of aquatic bacteria, algae, or other micro-organisms
an assemblage of microbial cells that is irreversibly associated (not removed by gentle rinsing) with a surface and enclosed in a matrix of primarily polysaccharide material
an assemblage of surface-associated microbial cells that is enclosed in an extracellular polymeric substance matrix
a population of microorganisms that grow on a surface and encase themselves in excreted layers of polysaccharide
a protective coating formed by organized microorganisms to shield themselves from antibiotics and the host's natural defenses
a slime-like mulitcellular bacterial colony that is typically highly resistant to conventional antibiotics
a slime-like multicellular bacterial colony that may form when bacteria attach to medical devices such as catheters, vascular grafts or endotracheal tubes
a thick layer made up of microorganism clusters
a thin layer composed of micro-algae, bacteria and their mucus and occur in all natural rivers and lakes
a thin layer of microorganisms that essentially glue themselves together in order to adhere to the surface of equipment or other structures
a thin layer of micro-organisms which form a slime on surfaces of a water system in direct contact with water
a thin usually resistant layer of microorganisms (as bacteria) that form on and coat various surfaces (as of catheters or water pipes)
a topographically and ecologically rich community composed of bacteria affixed to a surface by means of long-chained sugars that the bacteria produce
a thin layer of material that develops on rock surfaces as a byproduct of microbial activity.
Microorganisms and extracellular products associated with a substratum.
A layer of extracellular matrix containing quiescent, non-proliferating micro-organisms.
a collection of microorganisms, extracellular polymeric products, and organic matter located at the interface in solid-liquid, gas-liquid, or liquid-liquid biphasic systems.
A thin layer of biota that lives on substrate, such as rocks in creeks. Biofilm is composed of alga, fungi, bacteria. River rocks at North Cascades are slippery because of the thin layer of biofilm.
A thin layer of biota that lives o...
A coating or covering on the surface of a living or nonliving substrate composed of organisms like bacteria, protozoa, algae, and invertebrate animals.
Forms when bacteria attach to surfaces exposed to water, and begin to excrete a slimy, glue-like substance. It is common in water pipes.
A surface layer of microorganisms and other organic matter. It is usually combined with particulate matter, scale and products of corrosion.
In oil and gas pipelines, an established layer of microorganisms, consisting of produced exo-polymers, lipids, and metabolic waste products; often containing corrosion products and debris. Films may range from 5 microns to over 100 microns in thickness. Various bacterial species may be present within the biofilm and form synergistic chemical and structural relationships.
a matrix of microorganisms and extracellular material that attaches to surfaces that are bathed with liquids.
An accumulation of sessile microbial growth imbedded in a film of adhesive polymer and attached on the surface of a support material, such as the interior surface of water pipe or water storage vessels.
A biofilm is a complex aggregation of microorganisms marked by the excretion of a protective and adhesive matrix. Biofilms are also often characterized by surface attachment, structural heterogeneity, genetic diversity, complex community interactions, and an extracellular matrix of polymeric substances.
