PATENT ABSTRACTS

192

containing sodium chloride at a concentration of about 3M or above, wherein the algal suspension is contacted with an adsorbent having a hydrophobic surface so as to adsorb the algae thereon, and the adsorbent with the algae adsorbed thereon is separated from the brine, betacarotene and other useful cell components may be extracted from the adsorbed algae by treatment with a suitable solvent.

4556073 PROCESS FOR REDUCTION OF NITRATE CONTENT OF T O B A C C O BY M I C R O B I A L TREATMENT

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.
