    摘要： Enzyme-support complexes in which the enzymes are bound by covalent bonding to at least one reactive function of organic groups grafted to mineral supports by at least one ester bond. The complexes are obtained by reacting an insoluble inorganic support having hydroxyl groups with a compound formed of an organic group having at least one alcohol or phenol function and at least one reactive function, to which the enzyme is then bonded.

    摘要： A water treatment process is provided wherein water of a pH in the range of about 6 to 9 is treated with a flocculating agent, most preferably, an iron or aluminum comprising flocculating agent, and a flocculation additive comprising a heteropolysaccharide generated by the action of bacteria of the genus Xanthomonas or Arthrobacter, or fungi of the genus Sclerotium. The flocculating agent is added initially to the water, with the heteropolysaccharide comprising flocculation additive being added subsequent thereto. The process finds particular utility in the purification of potable waters.
