WebMar 21, 2024 · The meta-analysis revealed that regardless of polysaccharide type, depolymerised polysaccharides exerted superior inhibitory activity against Escherichia coli than against Staphylococcus aureus. Furthermore, low MW (< 10 kDa) anionic and non-ionic polysaccharides were more effective than chitosan (10–100 kDa) in this regard. Webmethylesterase (PME) activity, results in processed mate-rial with a firmer texture. This is because the lower degree of pectin methylesterification both increases Ca2+ cross-linking of the pectin chains and makes the pectin less sus-ceptible to thermal cleavage by b-elimination (Stolle-Smits, Beekhuizen, Recourt, Voragen, & Van Dijk, 2000). axis of symmetry in crystal is given by the general formula Webthe systems used in pectin methylesterase activity analysis.
