The study of microbial biofilms represents a thriving field in every aspect of microbiology, as biofilms play a pivotal role in medical microbiology, environmental microbiology, and microbial biotechnology alike. The investigation of the basic molecular mechanisms leading to biofilm formation, maintenance, and break-up, in different microorganisms, has led to the discovery of some of the most sophisticated signaling and regulatory pathways known to exist in the microbial world.
In this Special Issue of Microorganisms, we invite scientists with an interest in microbial (i.e., both bacterial and fungal) biofilms to send contributions concerning any aspect related to this field: from the role of mixed biofilms in different ecological niches, including industrial settings and complex microbial communities associated with the human body, to development of novel antimicrobial agents with antibiofilm activity, to investigations on microbial virulence linked to biofilm formation, to the basic regulatory mechanisms presiding over the various steps of the biofilm/planktonic cells cycle, to investigations on the impact of microbial biofilms on human health.
