WebNov 17, 2024 · In many studies, biofilms have been developed on synthetic material such as glass slides. However, natural sediment beds are very different from impermeable surfaces and provide a more extensive substratum for biofilm growth: the porous structure and rich nutrients allow the biofilm and related extracellular polymeric substance (EPS) … WebOct 15, 2024 · The preceding higher-order effects induced by biofilm formation are of ever-changing nature (Battin et al., 2016) mainly due to complex reciprocal interactions between flow, biofilm and sediment (Gerbersdorf and Wieprecht, 2015) and are also expected to change in a nontrivial way as a result of climate change (Piggott et al., 2015; Zeglin, 2015 ...

WebNov 20, 2024 · Biofilm-sediment aggregate (BSA) contains a high water content, either within internal pores and channels or bound by extracellular polymeric substances (EPS) forming a highly hydrated biofilm matrix. Desiccation of BSAs alters the biofilm morphology and thus the physical characteristics of porous media, such as the binding matrix within … WebJan 11, 2024 · Furthermore, biofilms can be a CO 2 sink on the sediment surface, suggesting that they can accumulate carbon (Chen S. et al. 2024). Biofilms that are rapidly buried may decompose slower in an anaerobic environment than at the surface, allowing greater carbon preservation. Biofilms exist in a delicate balance with sediment deposition. dales clothing store la crosse wi
