Opis

Application

• Enzymatic/chemical analysis of dietary fiber.: Focused on the analytical techniques for analyzing dietary fibers, which could be adapted for the analysis of complex organic matrices in the presence of DMSO ( Theander et al., 1994).


• Levans: I. Fractionation, solution viscosity, and chemical analysis of levan produced by Streptococcus salivarius.: This research details the fractionation and analysis of bacterial levan, which could inform studies involving the solubilization and analysis of similar polysaccharides in DMSO ( Ehrlich et al., 1975).
