Popis:	Emphasis during this quarter has been on the production of ..beta.. glucosidase (..beta..-G) from a microbial source and the immobilization of the ..beta.. glucosidase on suitable supports. ..beta..-G has been grown and isolated from Aspergillis phoenicis. The crude enzyme powder was used satisfactorily during later immobilization studies. The ..beta..-G was immobilized on Corning alumina by adsorption with activity retention yields above 40%. Preliminary data on the half life of this support show negligible loss of activity in a fluidized bed after 200 hours when operating on a cellobiose substrate.
