some of pathogenic and food spoilage bacteria can attach on food contact surfaces and form a biofilm, the source of contamination of foods. biofilm is a functional consortium of microorganisms attached to the surface and is embedded in the extracellular polymeric substances (eps) produced by the microorganisms. biofilms due to special structure and eps are more resistant to antimicrobial agents...

Biofilms are diverse communities of microorganisms embedded within a self-produced matrix of extracellular polymeric substance which are firmly attached to biotic or abiotic surfaces. Approximately 80% of all human infections are associated with biofilms and evidence for their role in an ever-growing number of cutaneous disorders is constantly unfolding. Biofilms present a difficult challenge t...

Biofilm is formed by one or different types of microbes that can grow on surfaces. Bacteria, fungi, and many protists form biofilms. formation requires cell to signaling mechanism which defined as quorum sensing. In this work, we have studied about the antibiofilm activity methanolic extract nutmeg against Gram-positive Bacillus subtilis bacteria. Our test inhibited biofilm production well erad...

Heavy metal pollution in soil and water has been of worldwide concern due to their biotoxicity/ecotoxicity the ecosystem, accumulation food chain, persistence environment. Microbially induced carbonate precipitation (MICP) is known as an efficient cost-effective biogeochemical process for remediation heavy metals contaminated This study reviews mechanisms biomineralization urease-producing micr...

Vanillin ― a bioactive substance to interfere various biological activities is reportedly able mitigate fouling in membrane bioreactor (MBR). However, impact of continuous dose vanillin on treatment performance and microbial MBR are still unknown. In this study, effects production extracellular polymeric substances (EPS) community was investigated lab-scale under vanillin. remarkably reduced ac...

According to the National Institutes of Health and the Center for Disease and Prevention, it is estimated that 65 to 80 percent of the human infectious are caused by biofilms. Antibiotics and drainage of purulent discharge are the main treatment measures. But in chronic infections sometimes these findings are not easy to recognize. Biofilm is an extracellular polymeric conglomeration generally ...

Abstract Structural extracellular polymeric substances (EPS) contribute to the bioflocculation performance of activated sludge systems. This research investigates potential bioaugmentation a structural EPS producer, Azoarcus communis, as improvement or remediation approach. An antibiotic-resistant and fluorescent protein-producing mutant was constructed monitor survival, persistence, location a...
