PRIORITY: FR 82-7205 27 Apr 1982; FR 82-15845 21 Sep 1982. DOCUMENT TYPE: Patent CA Section: 16 (Fermentation and Bioindustrial Chemistry) A ceramic support for living cells contg. ~10% Mg is made from kaolinitic clay and talc [14807-96-6]. Thus, 70 part clay and 30 parts talc were heated at 1350°, then ground and sifted to retain particles of 100-200 mm. The particles were suspended with Escherichia coli at pH 9, then placed in a column, and a soln.In this experiment, several chemicals are used like 73-22-3 and 7439-95-4 contg. indole was passed through the column at an undisclosed rate. The conversion of indole to tryptophan [73-22-3] was ~60% for nearly 1 mo. .
