Microenvironments can be defined as localised zones with chemical, biological or physical characteristics that differ significantly from those of the larger-scale surrounding environment. Because microbes respond primarily to these immediate conditions, microenvironments strongly influence the performance of microbially-based systems. Understanding and controlling these influences is essential for engineering improved systems.
This topic forms a key part of EBNetâs Theme 2, and complements broader UK research and innovation activities such as those of the National Biofilms Innovation Centre (NBIC).
Last year’s EBNet-supported workshop on Biofilm Microenvironments, coordinated by Dr Joe Weaver, aimed to:
- Develop the above shared definition of âmicroenvironmentâ.
- Explore the potential if microenvironments were perfectly controllable and measurable.
- Identify gaps between current knowledge and the idealized scenario.
- Establish priorities for bridging gaps and driving innovation.
- Assess institutional support needed, noting strengths and areas for improvement.
- Inventory existing skills and identify complementary skills for growth and collaboration.
Outputs from the workshop are now available on the Resources page in the form of a Position Statement, Outcomes & Recommendations, full Report and Executive Summary.
Progress in this area hinges on two interconnected priorities: improving system insight and control, and strengthening interdisciplinary integration. Dr Weaver noted that âWhile technological advances remain essential, one key conclusion from the participants was that the most immediate gains will come from enabling skill development, collaborative design, and streamlined institutional supportâ.
EBNet is delighted to have enabled the workshop discussions, and looks forward to further developments in this rapidly-developing and intellectually exciting area.
