...Benjamin J. Allardyce; Stuart M. Linton SUMMARY Laminarinase and endo-β-1,4-glucanase were purified and characterised from the midgut gland of the herbivorous land crab Gecarcoidea natalis and the crayfish Cherax destructor . The laminarinase isolated from G. natalis was estimated to have...

... cellulose to glucose. The digestive juice of both species also contained laminarinase,licheninase and xylanase, which hydrolysed laminarin, lichenin and xylan,respectively, to component sugars. The pH optima of β-1,4-glucosidase,endo-β-1,4-glucanase and total cellulase from G. natalis were 4–5.5, 5.5...
