- Microbial extracellular polymeric substances (EPS) modify water retention in BSCs.
- The link between EPS and the matric potential of intact cyano-BSC was shown.
- EPS in BSCs maintained matric potential stable along dehydration to 20% RWC.
Biological Soil Crusts (BSCs) represent an important part of the living cover in drylands worldwide. BCSs change soil hydrology due to extracellular polymeric substances (EPS)-excreting species of cyanobacteria, dominant members of dryland-BSCs. The presence of EPS allowed matric potential (Î¨m) to remain unchanged down to 20% water content, whereas, without EPS, Î¨m started decreasing at 80% water content. The EPS matrix improved the water retaining capacity of soil, suggesting that BSCs would delay onset of restrictive matric potential values due to its larger water holding capacity.
