4542100 STRAIN OF PSEUDOMONAS PUTIDA FOR PRODUCING AN INTERMEDIATE COMPOUND IN THE PRODUCTION OF PARACRESOL Scott Hagedorn assigned to Celanese Corporation The present invention provides a process for the production of p-cresol in a quantitative yield, which involves the acidification of an aqueous solution of the starting, material, 4methyleyclohexa-3,5-diene-I, 2-diol-lcarboxylic acid, under ambient conditions of temperature and pressure to cause spontaneous decomposition of the starting material to pcresol. The starting material is produced with Pseudomonas putida Biotype A strain ATCC 39119. 4543331 FERMENTATIVE OR ENZYMATIC PRODUCTION OF 2-KETO-LGULONIC ACID Takayasu Sonoyama, Shigeo Yagi, Bunji Kageyama, Osaka. Japan assigned to Shionogi & Co Ltd Fermentative or enzymatic production of 2keto-L-gulonic acid from 2, 5-diketo-D-gluconic acid using living or processed mutants, being defective in metabolizing 5-keto-D-gluconic acid and incapable of producing 2-keto-D-gluconic acid. The mutant is derived from 2-keto-Lgtuconic acid producing microorganisms of genus Corynebacterium. The production is carried oat in the presence of nitrates and/or hydrogen donors in a preliminarily sterilized fermentation broth in which a 2, 5-diketo-Dgluconic acid producing microorganism ofgenRs Gluconobacter or Erwinia has been cultivated.

4546081 CONTINUOUS ALCOHOL FERMENTATION PROCESS USING IMMOBILIZED YEAST

carbohydrate-containing substrate liquid through a vessel packed with a thin film means having yeast immobilized therein. Surfaces of the thin film means extend in the direction of flow within the vessel to provide elongated parallel passages. The thin film means occupies from 10 to 65°0 of the volume of the vessel and preferably has a thickness of 0.1 to 3 ram. Preferably, the thin film means is formed by mixing an aqueous yeast suspension with a photocrosslinkable resin and subjecting the mixture to radiation to photo-crosslink the resin. 4548974 A N T I B I O T I C S P R O D U C E D BY KIBDELOSPORANGIUM ARIDUM SHEARER Betty Bowie, David J Newman. Marcia Shearer, Robert Sitrin, Joseph Valenta assigned to SmithKline Beckman Corporation A novel antibiotic complex of Vancomycin-like antibiotics, AAD 216 complex, is produced by the cultivation of a fermentation broth containing Kibdelosporangium aridum Shearer gen. nov., sp. nov. ATCC 39323 microorganisms in an aqueous nutrient medium under submerged aerobic conditions. The AAD 216 complex and its major bioactive components; AAD 216A, A A D 216B, and AAD 216C exhibit antibiotic activity and growth promotant activity. 4551533 ANTIBIOTIC

Taikwang M Lee, Donald B Borders. Joseph J Goodman, Raymond T Testa, William M Maiese, David Labeda assigned to American Cyanamid Company Antibiotic LL-D42067 alpha derived by aerobic fermentation of the microorganism Actinomadura madurae subspecies simaoensis NRRL 15734, useful as an antibacterial and antiparasitic agent. 45543~ METHOD

4559301 PROCESS FOR PREPARING MACROCIN DERIVATIVES Jan R Turner. Veronica Krupinski. David S Fukuda. Richard H Bahz assigned to Eli Lilly and Company New macrocin and lactenocin ester derivatives of the formula: See Potent lbr Chemical Structure wherein R is formyl or hydroxymethyk R I is hydrogen, acetyl or propionyl: R2 is hydrogen or See Patent Jor Chemical Structure and R3 is hydrogen, acetyl, propionyl, n-butyryl or isovaleryl: provided that one of R1 or R3 must be other than hydrogen: and the acid addition salts thereof; prepared by bioconversion of macrocin or lactenocin with an acylating enzyme system produced by Streptomyces thermotolerans strains, have improved activity against Mycoplasma species.

Lawrence Gravely, Vernon Geiss, Charles Gregory assigned to Brown & Williamson Tobacco Corporation A process for the reduction of the nitrate content of tobacco materials by microbial treatment is disclosed wherein tobacco materials are subjected, under controlled conditions, to the action of a microorganism effective to degrade nitrates through a biochemical reaction. Tobacco materials treated in accordance with this process, when incorporated into a tobacco smoking product, produce a mild smoke having reduced nitrogen oxides and hydrogen cyanide deliveries without loss of desirable flavor, taste or other smoking properties.

4559313 REMOVAL OF INORGANIC CONTAMINANTS FROM CATALYSTS Allan S Myerson, William R Ernst assigned to Georgia Tech Research Institute Spent catalysts containing metal impurities are treated by a process comprising treating the spent catalyst with a solution containing oxidizing ferric ion a n d o r oxidizing bacteria, thereby freeing said spent catalyst of said metal impurities.

PROCESS FOR HYDROLYSIS OF BIOMASS Alvin O Converse, Hans E Grethlein assigned to Trustees of Dartmouth College A process for hydrolysis of biomass wherein the biomass is mixed with a small amount of an aqueous acid to produce a wet meal. A nonaqueous carrier fluid is used to form a slurry of the biomass, and the temperature and pressure are established at appropriate levels to effect hydrolysis of the biomass to decomposition products that include sugar for a time period that is sufficient for the hydrolysis to occur.

PRODUCTION OF GAMMADECALACTONE Mohamad 1 Farbood, Brian J Willis assigned to Fritzsche Dodge & Olcott lnc Optically active gamma-decalactone is produced by culturing a microorganism capablc of hydrolyzing castor oil and effecting betaoxidation of the resulting hydrolysate in the presence of castor oil or castor oil hydrolysate and a co-oxidant. The resulting gammahydroxydecanoic acid is [actonized to form gamma-decalactone.
