Genomics Approach

Abstract

Biofilm is an essential strategic structure for microorganisms such as bacteria to grow stably in an aquatic environment. Its universal presence in the aquatic environment is a piece of evidence. In biofilm formation, microbes adhere to a surface of solid substrates using flagella or pili, which are microbial locomotors, and start proliferating. Quorum sensing is then induced by signal molecules termed autoinducers. Then large amounts of extracellular polysubstances are produced to form a biofilm in which sessile bacteria are encased.
