β-(1→3) Glucanases from plant callus cultures

Enzymes capable of hydrolyzng β-(1→3) glucan (laminarin) have been found in callus cultures of bean (Phaseolus), lettuce (Lactuca), carrot (Daucus) and pepper (Capsicum). Laminaribiose is the major product. Lichenin and oat glucan were not attacked by these laminarinases.
