Fig. 11. Activity of laminarinase (µmol reducing sugars produced
min–1 ml–1) purified from the midgut glands
of G. natalis (
) and C. destructor (
) with
increasing concentrations of laminarin. Lines running through the data have
been created after the data were fitted to the Michaelis–Menten enzyme
kinetics model. Laminarinase from G. natalis had a
Vmax of 42.04 µmol reducing sugars produced
min–1 mg protein–1 and a
Km of 0.1259% (w/v). Laminarinase from C.
destructor had a Vmax of 19.6 µmol reducing sugars
produced min–1 mg protein–1 and a
Km of 0.059% (w/v).
