method of producing biochemically active material immobilized on porous glass fiberous material and the fiberous product with the immobilized biochemically active material where immobilization is on one or more surfaces are described which provide readily useable forms of biochemically active material for industrial and commercial applications. The method includes: forming solid or hollow pore generating glass fibers from a fiberizable, glass forming batch composition, attenuating the glass fibers, generating pores in the glass fibers to produce porous silica-rich fibers having a mean pore diameter at least greater than the minimum exclusion diameter of the nonliving biochemically active material and at least greater than the minimum exclusion diameter of related materials for living biochemically active material, immobilizing the biochemically active material through adsorption, entrapment and/or chemical bonding on one or more surfaces of the porous glass fibers and maintaining the activity of the immobilized biochemically active material. The porous fiberous material with immobilized biochemically active material has dimensions ranging from particles to fibers having a fiber diameter of about 3 to about 150 microns and a length of less than 1 inch to a continuous length. The mean pore diameter ranges from about 300 to about 3000 angstroms and the pore volume is consistent with a surface area of greater than about 10m2/9.
