Structurally stable but functionally disrupted marine microbial communities under a future climate change scenario: Potential importance for nitrous oxide emissions

“…Ocean acidification (OA) and warming (OW), alone or in combination, did not significantly affect alpha diversity nor composition of microbial communities on the shell surface of blue mussels. Such a low compositional and structural susceptibility of biofilm communities to OA, OW, and climate change (CC) is surprising since several studies have reported that bacterioplankton communities (Lindh et al, 2013;Wang et al, 2021), bacterial consortia on living (Mensch et al, 2020(Mensch et al, , 2016 and inert surfaces (Ferguson et al, 2021) are sensitive to these stressors, notably OW. The blue mussel inhabits coastal areas and microbes on their shell might thus be able to withstand environmental changes projected for the end of the 21 st century.…”

Bacteria Colonies Modify Their Shear and Compressive Mechanical Properties in Response to Different Growth Substrates

“…Biofilms and other bacteria aggregate systems are collectives of bacteria that are typically surface bound and self-encased in an extracellular polymeric substance (EPS) matrix. , Biofilms can have beneficial effects on ecosystems such as soil and coastal environments, contributing to nutrient cycling and carbon balance. The resilience of multicellular bacterial biofilms, both in development and response to environmental stressors, has deleterious effects in medicine and engineering, contributing to microbial infections , and biofouling of water ways and industrial machinery .…”

Bacteria colonies modify their shear and compressive mechanical properties in response to different growth substrates

“…Biofilms and other bacteria aggregate systems are collectives of bacteria that are typically surface bound and self-encased in an extracellular polymeric substance (EPS) matrix [3, 4]. Biofilms can have beneficial effects on ecosystems such as soil [5] and coastal environments [6], contributing to nutrient cycling and carbon balance. The resilience of multicellular bacterial biofilms, both in development and response to environmental stressors, has deleterious effects in medicine and engineering, contributing to microbial infections [7, 8] and biofouling of water ways and industrial machinery [9].…”
