Microbial biofilm plays an important role in the life cycle of microorganisms surviving in diverse and harsh environments such as extremes of temperatures, pH, salinity, nutrient scarcity etc. Biofilm formation is a survival strategy adopted by microorganisms allowing colonization in new niches by dispersal of microbes from the microbial clusters embedded within an outer polymer layer produced by the microorganism itself. This layer comprises of extracellular polymeric substances (EPS) that helps the indwelling microbes to grow and divide in a protected environment against invaders like antimicrobial agents, surfactant, biocides and phagocytic cells of host organisms. Thus, EPS matrix prevents the penetration of antimicrobials thereby allowing the indwelling microbes to survive and give rise to antimicrobial resistance posing threat to human health.
The present book highlights a detailed analysis of the mechanism of biofilm formation in both Gram positive and Gram-negative bacteria and the role of quorum sensing signaling mechanism in the genetic regulation pathway.
The book titled "Natural Products: Alternative therapeutics as Quorum Sensing (QS) inhibitors" provides a detailed and systematic review of mechanism of quorum sensing in both Gram positive and Gram-negative bacteria and alternative pharmacological developments as a potent solution to the rise of antimicrobial resistance during biofilm formation.
Features:
- A systematic overview of the mechanism of quorum sensing in the development of microbial biofilms
- Biofilm formation and its role in the emergence of antimicrobial resistance.
- Recent pharmacological development of antibiofilm remedies involving biogenic compounds.
This book serves as a reference book for researchers investigating the progression of events during microbial biofilm formation starting from the genetic cascade regulating quorum sensing to secretion of autoinducers and design of safer methodologies for the successful eradication of microbial biofilm. It may also be used as a textbook for a undergraduate level course in microbiology or microbial biotechnology.

Dr. Taniya Roy Chowdhury
Tania Roy Chowdhury is working in Agricultural Research Service at US Department of Agriculture. Her research area is to study soil systems at two scales: the broadly ecological and the complexly microbial trying to understand the vital locus of biodiversity at the critical interfaces of soil, microbes, water and trace gas emissions, microbial underpinnings of biogeochemical changes with a focus on nutrient cycles (carbon, nitrogen, and iron), and specifically on anaerobic microbial processes, including methanogenesis. Ecosystems of interest include wetlands, permafrost, and converted agricultural lands. She is interested in studying connected urban waterways and tackling issues pertaining to environmental health. By applying a range of skills from microbiology, soil science, metabolomics, and high-throughput sequencing technologies, Her studies on the complex interactions between microorganisms and biotic/abiotic factors. The ultimate goal is to detect ecological patterns within a spatial-temporal framework to address management/sustainability challenges. Her extended research interests encompass around.
