PATENT ABSTRACTS
162 Enzymes and Enzyme Systems
raining the immobilized glucose isomerase and a pre-column containing the particles of SiO2 or aluminum silicate.
4532208 CONSTITUTIVE GLUCOSE ISOMERASE PRODUCER Edmund Hafner, Denise M Jackson assigned to UOP lnc A mutant Streptomyces coelicolor, NRRL 15398, produces glucose isomerase constitutively at a level at least as great as the parent does inductively in common growth media. The isomerase can be effectively used to isomerize glucose to fructose in a continuous process using immobilized enzyme.
4532211 COLIFORM BACILLUS HAVING A GENE FOR THE PRODUCTION OF STAPHYLOKINASE AND A PROCESS FOR PRODUCTION OF STAPHYLOKINASE THEREWITH Tomoyuki Sako, Saeko Sawaki, Toshizo Sakurai, Masahiko Mutai, Isamu Kondo, Tokyo, Japan assigned to Kabushiki Kaisha Yakult Honsha Novel coliform bacillus useful for industrial production of staphylokinase, a fibrinolytic enzyme, and process for the production of staphylokinase using said microbe are provided. The novel microbe comprises a recombinant DNA, carrying genetic information for the production of staphylokinase, said genetic information being DNA derived from a temperate phage DNA of Staphylococcus aureus.
4533633 PROCESS AND APPARATUS FOR ISOMERIZING GLUCOSE TO FRUCTOSE Gunter Weidenbach, Dirk Bonse, Boris Meyer, Hanover, Federal Republic Of Germany assigned to Kali-Chemie Aktiengesellschaft When isomerizing part of the glucose content of a glucose-containing solution to fructose, the productivity of glucose isomerase immobilized on an SiO2 carrier is increased considerably by pre-contacting the glucose-containing solution with particles of SiO2 or aluminum silicate. An apparatus is used having a reaction vessel con-

A mutated aroA gene is employed which expresses 5-enolpyruvyl-3-phosphoshikimate synthetase (EC: 2.5.1.19) (ES-3-P synthetase), Methods are provided for obtaining the aroA mutation which provides the enzyme resistant to inhibition by glyphosate, means for introducing the structural gene into a sensitive host, as well as providing a method of producing the enzyme. The E. coli strain C600(pPMGI) has been deposited at the A.T.C.C. on Dee. 14, 1982 and been given A.T.C.C. accession no~ 39256,
4536477 THERMOSTABLE GLUCOAMYLASE AND METHOD FOR ITS PRODUCTION Dennis M Katkocim Nancy S Word, ShiowShon Yang assigned to CPC International lnc This invention relates to a glucoamylase enzyme exhibiting thermostability at pH values between 6 and 7 which is derived from a spore-forming, thermophilic, anaerobic bacterium and to a process for its production. The glucoamylase is especially useful for the preparation of glucosecontaining syrups from starch.
