Biofilm formation

av J Lönn-Stensrud · 2009 · Citerat av 2 — The effect on biofilm formation was assessed either by adding furanone to the growth medium or by allowing biofilm to form on surface-adsorbed furanone.

Biofilm formation

Bacteria can attach to a variety of  Biofilm formation greatly enhances the survival of micro-organisms, providing structural support as well as protection from surrounding threats such as  The first step of biofilm formation is the reversible attachment to a surface through aspecific interactions between the bacterial wall and the substrate. The contact  Biofilm formation is an important biological concept in environmental microbiology, wherein the microbial cells adapt to multicellular lifestyle by formation of biofilm during which the bacterial cells are self-immobilized in extracellular polymeric matrix. This chapter provides an insight into the concept of biofilm formation by microorganisms traditionally/naturally and in bioelectrochemical systems.

Biofilm formation

Biofilm formation in E. coli is regulated by the presence of oxygen. In case of insuf-ficient oxygen supply biofilm does not form, since bac-teria cannot adhere to substrate surface (31). Studies on the influence of temperature on L. monocytogenes show-ed that biofilm did not form if temperature was high, 2013-01-29 · Biofilm formation is a major virulence factor contributing to the chronicity of infections. To date few studies have evaluated biofilm formation in infecting isolates of patients including both Gram-positive and Gram-negative multidrug-resistant (MDR) species in the context of numerous types of infectious syndromes. Biofilm formation in Staphylococcus aureus under in vitro growth conditions is generally promoted by high concentrations of sugar and/or salts.

Biofilm infections, which contribute to up to 80% of human microbial infections, are associated with common human disorders, such as diabetes mellitus and poor dental hygiene, but also with medical implants. Biofilm formation begins with planktonic, or free-swimming, bacteria, which land on a surface. Bacteria can attach to a variety of surfaces, from woods, metals, and plastics to living tissues and FORMATION OF BIOFILMS.

Biofilm formation is an endless cycle, in which organized communities of bacteria are encased in a matrix of extracellular polymeric substances (EPS) that hold microbial cells together to a surface [14, 15]; these are thought to be determinant in 65–80% of all microbial infections [16–18].
