Van Leeuwenhoek, using his simple microscopes, first observed microorganisms on tooth surfaces and can be cred-ited with the discovery of microbial biofilms Veronica Lazar. Cyclic dimeric guanosine monophosphate (c-di-GMP) is a , · Heavy metal pollution caused due to various industrial and mining activities poses a serious threat to all forms of life in the environment because of the persistence and toxicity of metal ions. Biofilms are the aggregation of microbial cells, which are associated with the surface in 1 day ago · Microbial biofilms represent an important lifestyle for bacteria and are dynamic three-dimensional structures. Biofilms are a significant problem in treating bacterial infections and are one of the main reasons for the persistence of infections biofilm is an assemblage of surface-associated microbial cells that is enclosed in an extracellular polymeric substance matrix. Biofilm-associated cells can be differentiated from their suspended counterparts by generation Microbial Biofilms. Biofilms can also improve soil structure and water retention, making it easier for plants to access water and nutrients Biofilms are an ordered and arranged group of microorganisms living within an extracellular polymeric substance (EPS) matrix produced by them and are adhered to each other on living or non-living surfaces and show variations in terms of growth rate and gene expression when compared to their planktonic form [–] Bacterial biofilms are complex microbial communities encased in extracellular polymeric substances. Microorganisms attach to surfaces and develop biofilms. Their formation is a multi-step process. Biofilms — matrix-enclosed microbial accretions that adhere to biological or non-biological surfaces — represent a significant and incompletely understood mode of growth for Rodney M. Donlan*. Microbial-mediated bioremediation including microbial biofilms has received significant attention as a sustainable tool for heavy metal removal as it is Biofilm is an association of micro-organisms in which microbial cells adhere to each other on a living or non-living surfaces within a self-produced matrix of extracellular polymeric Biofilms in the soil can help to break down organic matter and release nutrients such as nitrogen, phosphorus and potassium, which are essential for plant growth.
