In vitro fermentation of linear and α-1,2-branched dextrans by the human fecal microbiota

open access: yes, 2011
The role of structure and molecular weight in fermentation selectivity in linear α-1,6 dextrans and dextrans with α-1,2 branching was investigated. Fermentation by gut bacteria was determined in anaerobic, pH-controlled fecal batch cultures after 36h ...

A systematic approach to study the pH-dependent release, productivity and product specificity of dextransucrases

open access: yesMicrobial Cell Factories, 2019
Background Dextransucrases are extracellular enzymes, which catalyze the formation of α-1→6-linked glucose polymers from sucrose. These enzymes are exclusively expressed by lactic acid bacteria, which commonly acidify the extracellular environment due to

Permeability of renal peritubular capillaries to neutral dextrans dextrans and endogenous albumin

open access: yes, 1976
Renal lymph-to-renal vein concentration ratios (CL/CV) for neutral dextrans (18-42 A effective radii) and endogenous serum albumin were measured in rats before and during acute colume expansion with isoncotic plasma or Ringer solution.

Test of the 'glymphatic' hypothesis demonstrates diffusive and aquaporin-4-independent solute transport in rodent brain parenchyma

open access: yeseLife, 2017
Transport of solutes through brain involves diffusion and convection. The importance of convective flow in the subarachnoid and paravascular spaces has long been recognized; a recently proposed ‘glymphatic’ clearance mechanism additionally suggests that ...
