Vermiculite support for immobilized biological materials. Swann, W. E. (Genex Corp., USA). Belg. BE 897340 A1 14 Nov 1983, 25 pp. (French). (Belgium). CODEN: BEXXAL.Some commonly used reagents like 25459-05-6 and 110-15-6 are used in this experiment. ICI: C12. APPLICATION: BE 21-4 20 Jul 1983. PRIORITY: US 82-400141 20 Jul 1982; US 83-464376 7 Feb 1983. DOCUMENT TYPE: Patent CA Section: 16 (Fermentation and Bioindustrial Chemistry) Enzymes or enzyme-contg. microorganisms are adsorbed to vermiculite [1318-00-9] and then covered with a cross-linked polymer. Thus, 80 g of a paste of Escherichia coli cells contg. aspartase [9027-30-9] was mixed with 20 g vermiculite particles. After adsorption had occurred, 10 g polyethyleneimine [9002-98-6] was added, followed by 120 g of a 25% soln. of glutaric dialdehyde [111-30-8]. Stirring was continued until hard particles were obtained. The particles were used to pack a column, and a pH 8.5 soln. of 1.5M NH4 fumarate [32378-54-4] contg. 1 mM MgSO4 was passed through the column at 37° and 1 vol./h. The conversion of fumarate to aspartate [56-84-8] was 98.2% on day 1, 99.4% on day 16, and decreased to 91.3% on day 151. .
