Most of the microorganisms particularly bacteria live as biofilm at one or other phase of their life under natural conditions. The distribution of biofilms ranges from extreme environment to clinical settings. To one end they cause many infectious diseases on the other hand they are responsible for the degradation of many pollutants in nature. Understanding on biofilm may provide a way to utilize these tiny building as valuable sources.Understanding Microbial Biofilms: Fundamentals to Applications brings together contributions from pioneers across the globe from diverse areas that have facilitated the progress in biofilm studies. The focus of Understanding Microbial Biofilms: Fundamentals to Applications is to bring both fundamentals and applications of microbial biofilms to a distinct platform. From an thorough introduction to the microbial community, architecture, physiology, mechanisms and imaging of biofilms to biofilms in nature, from fungal, algal and bacillus biofilm control, to the molecular and biochemical aspects of bacterial biofilms Understanding Microbial Biofilms: Fundamentals to Applications is a compilation of the chapters on bacterial community and communication from different environments. It covers recent advancement in five foremost aspects of microbial biofilm concluding with several chapter on their biotechnological application. All chapters are written by experts who have been working on different aspects of microbial biofilms.
