BIOFILM Meaning and
Definition
-
Biofilm is a complex and structured community of microorganisms that adhere to surfaces and are embedded in a matrix of extracellular polymeric substances (EPS), such as polysaccharides, proteins, and nucleic acids. It forms a slimy and protective layer that can be found on various natural and man-made surfaces, including rocks, teeth, medical devices, and pipes.
The formation of biofilms begins with the attachment of individual microorganisms to a surface. Once attached, these cells start to multiply and secrete EPS, creating a protective matrix that provides structural support and helps the biofilm resist physical disturbances and antimicrobial agents. This matrix also facilitates communication and nutrient exchange among the microorganisms within the biofilm.
Biofilms are characterized by their resilience and the increased resistance they develop against antibiotic treatments and hand hygiene measures. This resistance is primarily due to the protective nature of the EPS matrix, which acts as a barrier, preventing antimicrobial agents from reaching the microorganisms within the biofilm.
The presence of biofilms can have significant implications in various fields, including medicine, industry, and environmental science. In medicine, biofilms can form on medical implants or catheters, leading to infections that are difficult to treat. In industries such as water treatment, biofilms can cause clogging and contamination of pipes and filters. In environmental science, biofilms play a crucial role in various ecosystems as they contribute to nutrient cycling and the breakdown of organic matter.
Understanding the formation, structure, and characteristics of biofilms is essential for developing effective strategies to prevent and control biofilm-related problems in different areas.
