Dextran dextrinase and dextran of Gluconobacter oxydans

open access: yesJournal of Industrial Microbiology & Biotechnology, 2005
Certain strains of Gluconobacter oxydans have been known since the 1940s to produce the enzyme dextran dextrinase (DDase; EC2.4.1.2)-a transglucosidase converting maltodextrins into (oligo)dextran. The enzyme catalyses the transfer of an alpha1,4 linked glucosyl unit from a donor to an acceptor molecule, forming an alpha1,6 linkage: consecutive ...

Mass transfer coefficients in cross-flow ultrafiltration [PDF]

open access: yes, 1989
Usually, in concentration polarization models, the mass transfer coefficient is an unknown parameter. Also, its variation with changing experimental circumstances is in question.

Characterizing anomalous diffusion in crowded polymer solutions and gels over five decades in time with variable-lengthscale fluorescence correlation spectroscopy [PDF]

open access: yes, 2016
The diffusion of macromolecules in cells and in complex fluids is often found to deviate from simple Fickian diffusion. One explanation offered for this behavior is that molecular crowding renders diffusion anomalous, where the mean-squared displacement ...

Nematic-Isotropic Spinodal Decomposition Kinetics of Rod-like Viruses [PDF]

open access: yes, 2006
We investigate spinodal decomposition kinetics of an initially nematic dispersion of rod-like viruses (fd virus). Quench experiments are performed from a flow-stabilized homogeneous nematic state at high shear rate into the two-phase isotropic-nematic ...

Regulatory effects of blood constituents on the function and metabolism of the cat brain in perfusion ezperiments. Brain perfusion with artificial blood containing low molecular dextran and amino acids [PDF]

open access: yes, 1967
As a link in a series of studies on the effects of blood constituents on the brain function by means of brain perfusion, we used four kinds of artificial blood; namely, the blood containing a low molecular dextran, one containing glutamic acid, one ...
