Journal Article
Molecular and chemical features of the excreted extracellular polysaccharides in Induced Biological Soil Crusts of different ages
TL;DR: It can be hypothesized that C-EPSs, which are dispersed in the soil and thus more accessible, have been rather easily degraded by the heterotrophic microorganisms dwelling in mature IBSCs and reduced to low MW carbohydrates that are easily metabolized by chemoheterotrophs.
Journal ArticleDOI
Studies on exopolysaccharide release by diazotrophic batch cultures of cyanospira capsulata
TL;DR: Diazotrophic batch cultures of Cyanospira capsulata producing large amounts of a soluble exopolysaccharide (EPS) were studied over a period of about 30 days under continuous illumination and the massive release of this polysaccharidic material made the cultures progressively more viscous.
Journal ArticleDOI
Characterization of exopolysaccharides produced by seven biofilm-forming cyanobacterial strains for biotechnological applications
Francesca Di Pippo,Francesca Di Pippo,Neil Thomas William Ellwood,Alessandra Gismondi,Laura Bruno,Federico Rossi,Paolo Magni,Roberto De Philippis +7 more
TL;DR: It was shown that the anionic nature of the exopolysaccharides was due to the presence of carboxylic and sulfated groups and is likely the main characteristic with industrial applicability.
Journal ArticleDOI
Factors affecting poly-β-hydroxybutyrate accumulation in cyanobacteria and in purple non-sulfur bacteria
TL;DR: The results seem to suggest that, in phototrophic bacteria able to synthesize both PHB and glycogen, the polyester acts mainly as a regulator of the intracellular reduction charge.
Journal ArticleDOI
Hydrogen production during stationary phase in purple photosynthetic bacteria
TL;DR: It is suggested for enhancing the biofuels to biomass production ratio under conditions of continuous cultivation with minimal cell growth, allowing a greater proportion of the cellular metabolic activity to be directed toward H2-production.
