Insight into biofilm-associated microbial life.
Microbes cohabit our planet and are engaged in a struggle for survival though on a microscopic scale. This endeavor allows them to develop and devise means for survival and proliferation. One such strategy is the formation of biofilms leading to establishment of a protected community. Such multi-communities may consist of harmful and pathogenic microbes, and they may cause economic problems and threats to human health. Biofilms are formed when microorganisms are typically attached to support surfaces. Biofilm-associated cells are sessile and differentiated from their suspended counterparts by generation of an extracellular polymeric substance matrix, reduced growth rates, and the up- and downregulation of specific genes. Biofilm formation is a complex process regulated by diverse characteristics of the growth medium, substratum, and cell surface. Development of strategies to control or prevent biofilms requires a thorough understanding of the biofilm development process. Biofilm research has witnessed exponential growth, and exciting findings have been reported. This has led us to visualize some previously un-thought-of and fascinating events. This article aims to provide an overview of biofilm research and associated challenges.
