    Notes: Papain was covalently coupled to ZrO2-coated porous glass by several different methods. These derivatives were characterized and their operational half-lives determined using casein substrate. Papain covalently coupled to the porous glass, previously converted to a carboxylic acid derivative, through amide linkage gave a 35 day operational half-life.

    Notes: A microbial protease was immobilized by covalent attachment, to porous glass. This material was characterized for pH optimum, thermal stability, and operational half-life using casein as substrate.The immobilized enzyme was used for preparation of soya hydrolysates, low in free amino acids with high solubility.

    Notes: The enzyme invertase has been covalently coupled to porous glass particles. The product is extremely stable over a long period of time. Kinetic values for the immobilized enzyme are similar to the native enzyme. Excellent enzymatic activity for the immobilized enzyme was exhibited over a broad pH range. The immobilized enzyme when continuously operated for one month was found to have an operational half-life of over 40 days.
