The arabinofuranosidase has a maximum activity at about pH 6.0 and at about 65.degree. C., maintains at least about 50% of its maximum activity at 70.degree. C. and pH 7.0 after 80 minutes, and has an isoelectric point of about 4.4. The arabinfuranosidase can be used in a method of hydrolyzing xylan present in wood pulp at temperatures of at least about 60.degree. C. and a pH of at least about 7.0. The arabinofuranosidase is used along with at least two xylanases and a xylosidase isolated from the above Bacillus stearothermophilus strains.Type: GrantFiled: April 6, 1995Date of Patent: February 13, 1996Assignee: Novo Nordisk A/SInventors: Bruce L. Zamost, Dana D. Elm

Patent number: 5489526Abstract: An isolated xylosidase from Bacillus stearothermophilus NRRL B-18659, Bacillus stearothermophilus NRRL B-18660 and Bacillus stearothermophilus NRRL B-18661 is disclosed. The xylosidase has a maximum activity at about pH 6.0 and at about 75.degree. C., maintains at least about 60% of its maximum activity at about 65.degree. C. and pH 7 after 4 hours, is resistant to end-product inhibition maintaining over 75% of maximum activity in the presence of 1 molar xylose and has an isoelectric point of about 5.0. The xylosidase can be used in a method of hydrolyzing xylan present in wood pulp at temperatures of at least about 60.degree. C. and a pH of at least about 7.0. The xylosidase is used along with at least two xylanases and an arabinofuranosidase isolated from the above Bacillus stearothermophilus strains.Type: GrantFiled: April 6, 1995Date of Patent: February 6, 1996Assignee: Novo Nordisk A/SInventors: Bruce L.

Patent number: 5487988Abstract: A process for the preparation of monoterpene compounds (such as perillyl alcohol, aldehyde and .alpha.-terpineol) from limonene is described. The process uses Bacillus stearothermophilus which is effective at high temperatures (55.degree. to 70.degree. C.). A preferred strain of Bacillus stearothermophilus is ATCC 55596.Type: GrantFiled: August 15, 1994Date of Patent: January 30, 1996Assignee: Board of Trustees Operating Michigan State UniversityInventors: Hae C. Chang, Patrick J. Oriel

Patent number: 5486458Abstract: There is provided a method of quantitative assay for 1,5-anhydroglucitol in a specimen characterized by effectively removing maltose present in the specimen using .alpha.-glucosidase. Maltose present in a specimen is previously converted into glucose by the action of .alpha.-glucosidase derived from a microorganism belonging to the genus Bacillus to remove the affect by maltose. Then 1,5-anhydroglucitol in the specimen is quantitatively determined.Type: GrantFiled: June 30, 1993Date of Patent: January 23, 1996Assignee: Nitto Boseki Co., Ltd.Inventors: Ryo Kojima, Yoshiro Sato, Takeshi Nagasawa

Patent number: 5486459Abstract: The invention is directed to biological processes and apparatus for determining the efficacy of a sterilization cycle based upon the recovery of activity of interactive enzyme systems comprising enzymes, coenzymes, catalysts, cofactors, substrates or any other necessary reagents. The invention provides a vital process for expediting sterility verification before utilization of the articles thought to be sterilized. The invention involves the rapid detection of any surviving interactive enzymatic activity which directly relates to the probability of any biological spores surviving in a test sample. An absence of a change indicates that the sterilization process had inactivated the enzyme system thereby preventing the interactive reaction from taking place which is a rapid equivalent to directly detecting the survivability of bacterial spores in a similar test.Type: GrantFiled: January 30, 1995Date of Patent: January 23, 1996Assignee: Medical College of OhioInventors: Jeffrey C. Burnham, George J. Hageage, Douglas Jambard-Sweet, Judy Hendricks
