Graphical abstractAbstractMicrobial communities organize into spatial patterns that are largely governed by interspecies interactions. This phenomenon is an important metric for understanding community functional dynamics, yet the use of predicting microbial interactions currently lacking. Here we propose supervised deep learning as a new tool network inference. An agent-based model was used to simulate spatiotemporal evolution two interacting organisms under diverse growth and interaction scenarios, data which subsequently train neural networks. For small-size domains (100 µm × 100 µm) over coefficients assumed be invariant, obtained fairly accurate predictions, indicated average R2 value 0.84. In application relatively larger (450 450 where varying in space, models correctly predicted distributions without any additional training. Lastly, evaluated our against real biological using Pseudomonas fluorescens Escherichia coli co-cultures treated with polymeric chitin or N-acetylglucosamine, hydrolysis product chitin. While P. can utilize both substrates growth, E. lacked ability degrade Consistent expectations, context-dependent across substrates, i.e., degrader-cheater relationship on polymers competition monomers. The combined machine algorithm successfully demonstrates how infer from spatially distributed data, presenting itself useful analysis more complex

Soil, a potential reservoir of antibiotic resistance genes (ARGs), is inhabited by numerous microorganisms. Many microorganisms in soil are embedded within self-produced matrix extracellular polymeric substances to form supracellular structures, i.e., biofilms. Representing the predominant microbial lifestyle soil, biofilms considered hot spots horizontal gene transfer. Herein, we discuss distribution, transfer, and fate ARGs environment at macro- micro-scales. Applications microfluidic platforms, with an advantage mimicking complex environments permitting study behaviors micro-scale, coupled high-throughput sequencing other innovative transfer also discussed. This review aims highlight neglected role spread expand current limited knowledge about microenvironment.
