A biofilm is a collection of microbial cells that have adhered to biotic surfaces such as plant cuticles or animal epithelia, as well as abiotic surfaces such as rocky substratum or catheter exteriors. The life cycle of a microorganism includes the fundamental process of biofilm formation for survival in diverse and harsh environments since it is a protected mode of growth allowing colonisation of new habitats by dispersal of microbes from the microbial clusters. The biofilm bound microorganisms remain embedded in an extracellular polymeric matrix that protects the indwelling cells from surfactants, biocides, several invaders like protozoans, and defences offered by the hosts like phagocytic cells. The biofilm bound recalcitrant microbes induce chronic and nosocomial diseases, posing a serious threat to public health. It has been observed that various antimicrobial drugs are able to successfully remove the planktonic (freely suspended) states of microbes as compared to the sessile (substrate-bound) forms, thus resulting in the development of antimicrobial resistance.Modern pharmacological strategies targeting the biofilm matrix differ from the conventional methods of antibiotic usage. This includes the use of natural compounds such as plant bioactive molecules, antimicrobial peptides, green synthesised nanoparticles, or secondary metabolites from other organisms that not only prevent the rise of antimicrobial resistance but are also safe for the host tissues.Biofilm Associated Antimicrobial Resistance and Its Recovery provides a detailed and systematic review of alternative pharmacological developments in the field of biofilm research.Features: A narrative overview of the mechanism of biofilm formation and its role in the emergence of antimicrobial resistance Recent research in the development of antibiofilm remedies involving biogenic compounds Advancements in biofilm detection methodologies with cutting-edge technologies This book serves as a resource for researchers who need to understand and analyze the progression of events during microbial biofilm formation, as well as design safer methodologies for its successful eradication. It may also be used as a textbook for a graduate level course in microbiology or microbial biotechnology.

Phytochemicals have been present in human diet and life since the birth of mankind, including the consuming of plant foods and the application of herbal treatments. This coevolutionary interaction of plants and people has resulted in humans' reliance on food and medicinal plants as sources of macronutrients, micronutrients, and bioactive phytochemicals. Phytochemicals can be used as adjuvant agents and sensitizers in traditional antibiotic and anticancer therapy, reducing the potential of selecting resistant microbial strains and cancer cells. Recent Frontiers of Phytochemicals addresses the many processes of potential phytochemical evaluation of known sources, with a focus on phytochemical and pharmacological evaluations, and computational research into the structures and pharmacological mechanisms of natural products and their applications in medicine, food and biotech.

Microbial Biofilms: Challenges and Advances in Metabolomic Study is a volume in the Advances in Biotechnology and Bioengineering Series. The volume covers the metabolomic characteristics of bacterial biofilms and examines the techniques used in the analysis of the metabolomics of the biofilm, its formation, and related infections. The book includes the metabolomics study of various types of biofilms and details new strategies in targeting metabolic pathways for inhibiting the biofilm. The book also describes various types of metabolomics studies like metabolomics of oral biofilm and metabolomics of biofilm by nosocomial microbes. It also points out the recent advancements on various aspects of metabolomics studies pertaining to biofilms, related infections, their pathogenesis, and present-day treatment strategies. Microbial Biofilms: Challenges and Advances in Metabolomic Study is a helpful resource to scientists and researchers engaged in biofilm studies, precisely on the metabolomic changes at molecular level occurring in the participating microorganisms. It is also fascinating and thought provoking for the clinicians and health professionals actively involved in the treatment of biofilm mediated chronic infections, since it depicts the pathogenic consequences of the small molecular interactions of the metabolites in biofilm.
