Aims:  Investigate if the antibacterial effect of sphagnan, a pectin‐like carbohydrate polymer extracted from Sphagnum moss, can be accounted for by its ability to lower the pH. 
Antibacterial activity of sphagnum acid and other phenolic compounds found in Sphagnum papillosum against food‐borne bacteria
TLDR
The phenolic compounds in the leaves of Sphagnum papillosum are identified and their antibacterial activity at pH appropriate for the undissociated forms is examined.
A polysaccharide extracted from sphagnum moss as antifungal agent in archaeological conservation
TLDR
The aim of this chapter is to provide a chronology of key events and events from 1989 to 2002, which led to the publication of the Comic Sans- sans-serif.
Cell-wall polysaccharides play an important role in decay resistance of Sphagnum and actively depressed decomposition in vitro
TLDR
The role of polysaccharides in resistance to, and active inhibition of, microbial mineralization in Sphagnum-dominated litter is emphasized, as the poly Saccharides displayed decay-inhibiting properties hitherto associated with phenolics.
Valuable applications for peat moss
TLDR
The structural and chemical properties of Sphagnum are reviewed together with their suggested uses to facilitate new efforts to find commercially feasible applications for these extraordinary plants.
Untargeted metabolomic profiling of Sphagnum fallax reveals novel antimicrobial metabolites
TLDR
Characterizing the metabolite profile of Sphagnum fallax provided a baseline to understand the mechanisms in which SphagnUM fallax acts on its environment, its relation to carbon sequestration in peatlands, and provide key biomarkers to predict peatland C store changes (sequestration, emissions) as climate shifts.
Pectin shows antibacterial activity against Helicobacter pylori
TLDR
The results show that pectin produced antibacterial effects on all the 16 clinical isolates and 2 reference strains of H. pylori with the greatest antibacterial effect at a low pH (5.0) versus higher pHs.
Depolymerized RG-I-enriched pectin from citrus segment membranes modulates gut microbiota, increases SCFA production, and promotes the growth of Bifidobacterium spp., Lactobacillus spp. and Faecalibaculum spp.
TLDR
Modulations of gut microbiota by commercial pectin, WRP and its depolymerized fraction (DWRP) with different RG-I contents and Mw were compared in vivo and it was revealed by 16s rRNA high-throughput sequencing thatWRP and DWRP mainly composed ofRG-I modulated the gut microbiota in a positive way.

TLDR
The ion-exchange properties of Sphagnum russowii cell wall material were studied in the context of the Donnan weak acid model to reveal two classes of ions: Na+, Ca2+, or La3+.
Cation-exchange capacity and galacturonic acid content of several species of sphagnum in Sandy Ridge Bog, central New York State

TLDR
The high recovery of antagonistic isolates strongly suggests that bryophytes represent an ecological niche which harbors a diverse and hitherto largely uncharacterized microbial population with yet unknown and untapped potential biotechnological applications, e.g., for biological control of plant pathogens.
Studies in polysaccharide production and growth of Azotobactervinelandii MTCC 2459, a plant rhizosphere isolate
TLDR
Azotobacter vinelandii MTCC 2459, a novel exopolysaccharide producer, was isolated from Nelumbium nelumbo (lotus) stem, indicating the potential of the organism for production of useful EPS on a large (industrial) scale.
