Method Overview
This enzyme assay measures polysaccharide hydrolysis by time course incubation with RBB labeled polysaccharides[1].
Applicable variants include: bulk.
Scale of measurement
Spatial resolution is low (horizontal) and low (vertical). Temporal resolution is low, with a time integration of hours to days.
Data generated
Yields rates in units of relative OD units.
Units & currency
Units are relative OD units. The currency is carbon.
Sample size
< L.
Repositories & databases
Limitations
rate measurements at max (Vmax). bottle effects, potential rates.
