5356809 PROCESSES FOR IN VIVO PRODUCTION OF ASTAXANTHIN AND PHAFFIA RHODOZYMA YEAST OF ENHANCED ASTAXANTHIN CONTENT Johnson Eric A; Yang Huei-hsiung; GeldiayTuncer Beril; Hall William T; Schreiber David; Ho Kwok Madison, WI, UNITED STATES Assigned to Igene Biotechnology Inc An economical process for in vivo production of the pigment astaxanthin, and particularly a process for enhandng astaxanthin content of cultures of microorganisms of genus Phaffia, the process comprising culturing a microorganism of genus Phaffia in a nutrient medium containing an antibiotic, a cytochrome B inhibitor, or a terpenoid synthetic pathway inhibitor, cultivating surviving pigment enhanced microorganisms, and harvesting the yeast. 5356810 ASTAXANTHIN-PRODUCING YEAST CELLS, METHODS FOR THEIR PREPARATION AND THEIR USE Fleno Bent; Christensen lb; Larsen Robert; Johansen Steffen R; Johnson Eric Stenlose, DENMARK Assigned to Gist-brocades N V An isolated pure culture of a strain of Phaffia rhodozyma which produces astaxanthin in an amount of at least 600 mug per g Phaffla rhodozyma dry matter, as determined by HPLC analysis.
Disclosed herein is purified isolated angiogenic factor, isolated from Live Yeast Cell Derivitive. Also disclosed herein are methods to treat mammals suffering from wounds or burns comprising administering the angiogenic factor and pharmaceutical formulations for use in the methods. 5370999 TREATMENT OF FIBROUS LIGNOCELLULOSIC BIOMASS BY HIGH SHEAR FORCES IN A TURBULENT COUETI'E FLOW TO MAKE THE BIOMASS MORE SUSCEPTIBLE TO HYDROLYSIS Smart Earnest D Brenham, TX, UNITED STATES Assigned to Colorado State University Research Foundation High-shear, microcavitation is used to shred and disintegrate fibrous lignocellulose-containing biomass to make the biomass more susceptible to hydrolysis. This process is preferably done with the biomass particles dispersed in a slurry created using only water. The process can be performed on slurries created with other liquids such as liquid ammonia, aqueous solutions of acid or alkali reagents, or enzyme solutions containing celhilase. High-shear microcavitatiou is carried out by subjecting the slurry to high-shear forces by injecting the slurry cross currently into a tm'bulent Coaette flow created in a highfrequency, rotor-stator device. This microcavitation shatters the fibrous structure of the biomass in the slurry thereby creating a sheared slma-y. The device has a chamber containing a fixed stator equipped with coaxial toothed rings meshing with opposing coaxial toothed rings coupled to a rotor that is coupled to a rotatable shaft.

A multi-purpose resin synthesized from a mixture of a protein and a carbohydrate by ammoniation instead of hydrolysis is described. Any primary product of photosynthesis (glucose, starch or
PATENT ABSTRACTS lignocelhilose) is qualified for use as the carbohydrate component of the resin, which is an expedient, low-cost and benign substitute for conventional thermoseuing resins in the manufacture of numerous industrial products. 5372816 TREHALOSTATIN AND PROCESS FOR THE PREPARATION THEREOF Murao Sawao; Shin Takashi Assigned to Suntory Limited

This invention relates to the substance Trehalostatin which is a white powder soluble in water but hardly or only slightly soluble in hexaue, benzene, ethers and pelroleum ether, shows no absorption maxima at 220 nm or above in its ultraviolet visible light absorption spectrum, is positive in Rydon-Smith reaction and negative in nynhydrin reaction, 3,6-dinitrophthalic acid reaction and Elson-Morgan reaction, and has an RF value of 0.37 in Merck Kieselgal 50 F254 thin-layer chromatography using 3:1:2 mixttu~e on n-butanol, acetic acid and water as a developing solvent, Rt of 11.0 minutes in YMC PA03 (0.7 *27 cm) high performance liquid chromatography using 65% v/v acetonitrile (in H20) as a solvcut at a flow rate of 1.0 ml/min, a molecular weight of 366, (alpha)D of +115 degrees, and specific NMR spectrum. Also disclosed is a process for preparing trehalostatin and a specific strain of Amycolatopsis trehalostatica which has FERM accession number BP-2784. In addition the trchalostatin compound shows an inhibitory effect against trehalase in insects, especially Aldrichina grabami, even at a very low concentration and is therefore useful as an insecticide. 5372939 COMBINED ENZYME MEDIATED FERMENTATION OF CELLULOUS AND XYLOSE TO ETHANOL BY SCHIZOSACCHAROYCES POMBE, CELLULASE, BETAGLUCOSIDASE, AND XYLOSE ISOMERASE Lastick Stanley M; Mohagbegtd AI; Tucker Melvin; Grohmann Karel Longmout, CO, UNITED STATES Assigned to The United States
