Enrichment and application of extracellular nonulosonic acids containing polymers of Accumulibacter

Abstract: Pseudaminic and legionaminic acids are a subgroup of nonulosonic acids (NulOs) unique to bacterial species. There is a lack of advances in the study of these NulOs due to their complex synthesis and production. Recently, it was seen that “Candidatus Accumulibacter” can produce Pse or Leg analogues as part of its extracellular...

Catabolism of sialic acids in an environmental microbial community

Sialic acids are a family of nine-carbon negatively charged carbohydrates. In animals, they are abundant on mucosa surfaces as terminal carbohydrates of mucin glycoproteins. Some commensal and pathogenic bacteria are able to release, take up and catabolize sialic acids. Recently, sialic acids have been discovered to be widespread among most...
