“…This can allow highly localized electrochemical measurements and have been used in mammalian systems to study respiration, local charge and membrane transport [112][113][114]. While SPM is only beginning to be applied to microbial cells [115,116], localized micro-electrode measurements have been combined with fluorescence in situ hybridization (FISH) (discussed below) in microbial biofilms to relate community structure to specific metabolic functions such as sulfate reduction and nitrification [79].…”

Spatial organization is the norm rather than the exception in the microbial world. While the study of microbial physiology has been dominated by studies in well-mixed cultures, there is now increasing interest in understanding the role of spatial organization in microbial physiology, coexistence and evolution. Where studied, spatial organization has been shown to influence all three of these aspects. In this mini review and perspective article, we emphasize that the dynamics within spatially organized microbial systems (SOMS) are governed by feedbacks between local physico-chemical conditions, cell physiology and movement, and evolution. These feedbacks can give rise to emergent dynamics, which need to be studied through a combination of spatio-temporal measurements and mathematical models. We highlight the initial formation of SOMS and their emergent dynamics as two open areas of investigation for future studies. These studies will benefit from the development of model systems that can mimic natural ones in terms of species composition and spatial structure.

Iron and steel slags are being used, on a trial basis, as environmental remediation agents for marine sediments in rocky coastal waters. In addition to chemical risk such as component leakage of slag into the environment, formation of biofilms is inevitable due to the adhesion of environmental microorganisms to slag surfaces. The transformation of free-living microorganisms into biofilm forms not only alters microbial behavior and various physicochemical tolerances, but also changes the properties of the material. However, the impact and effects of biofilms on materials remain unclear due to the challenges of performing detailed analyses of biofilms on materials such as chemically active slag. Therefore, in this study, slags coated with biofilms were prepared and their chemical effects were investigated to determine whether microbes improve slag function. Furthermore, prior to determining the effects of the slag coated with biofilm, quantitative evaluation techniques for assessing slag biofilms were developed. The review is specifically focused on accurate quantitative evaluation methods for assessing biofilms on slag. Additionally, changes in the chemical properties of slag-coated biofilms are summarized. This technique for modifying slags using microbial biofilm can be applied to the development of novel materials, not only for slag but also for other materials, as material processing and surface treatment technology.
