Novel bacterium, Acetobacter altoacetigenes MH-24, useful for the fermentation production of vinegar
Patent number: 4654306Abstract: A novel species of acetic acid bacteria belonging to the genus of Acetobacter, to which a scientific name of Acetobacter altoacetigenes MH-24 (FERM BP-491) is given. The bacteria can grow in a culture medium containing at least 4 w/v % of acetic acid with a pH of 3.5 at the highest. Pure samples of species have been isolated and used for the fermentation production of vinegar without undertaking the conventional inoculation process using the prior art seed vinegar to provide a high-quality vinegar of high acetic acid concentration such as white vinegar, with high production efficiency.Type: GrantFiled: February 21, 1985Date of Patent: March 31, 1987Assignee: Nakano Vinegar Co., Ltd.Inventors: Etsuzo Entani, Seiichi Fujiyama, Shoji Ohmori, Hiroshi Masai -
Patent number: 4634667Abstract: Process for preparing a heteropolysaccharide from strain NCIB 11883 and use of the latter e.g. as viscosity modifier in an aqueous system such as completion fluids, work over fluids, stimulation fluids, and preferably in drilling fluids and use in connection with well-treatments, and enhanced oil recovery.Type: GrantFiled: September 24, 1984Date of Patent: January 6, 1987Assignee: Shell Oil CompanyInventors: John D. Linton, Michael W. Evans, Andrew R. Godley

Patent number: 4623624Abstract: Highly active pancreatin is obtained by autolysis of an aqueous isopropanol-containing tissue slurry, preferably buffered with sodium bicarbonate, until a test precipitation with aqueous isopropyl alcohol proves positive, and precipitating the batch with a higher concentration of isopropyl alcohol, resulting in a fiber suspension which can be sieved so that the solution obtained permits direct isolation of pancreatin by further increasing the concentration of isopropyl alcohol. A high bulk density of the finished dry preparation is achieved by stirring the precipitated pancreatin with isopropyl alcohol or acetone so as to bring the pancreatin to a concentration of 70-85% of isopropanol or 80-95% of acetone, isolating the pancreatin by suction filtration or centrifuging and drying it by treatment with dry air or nitrogen.Type: GrantFiled: December 23, 1983Date of Patent: November 18, 1986Assignee: BASF AktiengesellschaftInventor: Hans Schultze

Patent number: 4612285Abstract: A novel antibiotic, awamycin, and its production. Awamycin is active against gram positive bacteria and exhibits growth inhibitory activity against Erhlich ascites and Sarcoma 180 cells. Some of the identifying characteristics of awamycin include a molecular weight of 744.+-.1 (mass spectrum analysis), an elementary analysis of 59.16% C, 6.48% H and 1.88% N; a melting point of 158.degree. C.; an optical rotation of [.alpha.].sub.D 24=+836.degree.. Awamycin is an acidic substance, which provides an orange colored powder, and is poorly soluble in water.Type: GrantFiled: October 25, 1983Date of Patent: September 16, 1986Assignee: Kitasato InstituteInventors: Iwao Umezawa, Kanki Komiyama

Patent number: 4608343Abstract: This disclosure describes four new antibacterial agents designated LL-C08078.alpha..sub.1, LL-C08078.alpha..sub.2, LL-C08078.alpha..sub.3 and LL-C08078.beta. produced in a microbiological fermentation under controlled conditions using a new strain of a new species of the genus Streptomyces called Streptomyces majorciensis Labeda, sp. nov., and mutants thereof. These new antibacterial agents are active against a variety of microorganisms and thus are useful in inhibiting the growth of such bacteria wherever they may be found. In addition, these agents are active as growth promotants in warm-blooded animals.Type: GrantFiled: May 30, 1985Date of Patent: August 26, 1986Assignee: American Cyanamid CompanyInventors: David P. Labeda, Joseph J. Goodman, Donald B. Borders, Raymond T. Testa, John H. E. J. Martin, deceased

Patent number: 4604352Abstract: Starch is converted directly to ethanol by growing a co-culture of Clostridium thermosulfurogenes and Clostridium thermohydrosulfuricum under anaerobic conditions on a starch containing substrate in a medium comprising essential vitamins, minerals and growth factors. The co-culture also produces the thermostable enzymes .beta.-amylase, glucoamylase and pullulanase.Type: GrantFiled: September 18, 1984Date of Patent: August 5, 1986Assignee: Michigan Biotechnology InstituteInventors: Joseph G. Zeikus, Hyung-Hwan Hyun

Patent number: 4591561Abstract: A process for the preparation of maltopentaose is disclosed, comprising cultivating a maltopentaose-producing microorganism belonging to a genus Bacillus in a medium and isolating the thus-accumulated maltopentaose from the culture broth. A typical example of the maltopentaose-producing microorganism is Bacillus cereus NY-14. This process permits the preparation of maltopentoase without the use of amylase as in conventional methods. Maltopentaose is useful, for example, as a substrate for the determination of serum amylase.Type: GrantFiled: August 26, 1983Date of Patent: May 27, 1986Assignee: Sapporo Breweries LimitedInventors: Naohiro Yoshigi, Takahide Chikano, Yoshitada Mori
