5196327 Process for producing antifungal fermentation products and compositions thereof
PATENT ABSTRACTS A bacterial-assisted heap leach process is employed for the solubilization of a metal from a refractory ore containing fines and/or clay wherein at least a portion of the metal is solubilized by the bacterial oxidation of sulfides and the concomitant or sequential dissolution of the metal into a leaching solution. For some metals, the leaching solution has a pH of greater than about 9. The improvement in the process inciudes the application of an aqueous solution of acrylamide polymer to the ore in an amount effective to agglomerate the fines and/or clay prior to heap formation. The acrylamide polymer has a molecular Weight of at least 500,000 and is comprised of from about 0 to about 100 mole percent of (meth)acrylamide met units and from about 0 to 100 mole percent of Nsulfoalkyi(meth)acrylamide mer units. The acrylamide polymer is preferably applied to the ore as an aqueous solution formed at least in part by recycled bio solution.

5196069 APPARATUS AND METHOD FOR CELLULOSE PROCESSING uSING MICROWAVE PRETREATMENT Hatice Cullingford, Clifford E George, George R Lightsey assigned to The United States of America as represented by the United States National Aeronautics and Space Administration A method for pretreating a cellulosic waste product with microwaves is disclosed as well as a method and apparatus for converting cellulosic wastes into soluble saceharides. The invention greatly enhances a reaction rate for enzymatic hydrolysis. A feed mixture of cellulose, water and acetic acid are irradiated with microwaves at a superatmospheric pressure in an autoclave reaction vessel and the treated cellulose is enzymatically hydrolyzed in a bioreactor. The acid and enzymes are optionally separated for reuse. As a feed stock for the culture of microbes, the sugars can be further processed into ethanol or food protein. High yield, low hazard potential, low energy usage and ready preparation in space of acetic acid and the enzyme makes the present invention well suited for use on long duration space missions.
Maria B Lopez, Richard L Monaghan assigned to Merck & Co Inc A mixture of derivatives of 2-amino-3, 4, 5, 14tetrahydroxy - 6 - eicosenoic acid has been isolated from a culture medium after cultivation of microorganisms belonging to the genus Aspergillus. The compounds are useful as antifungal agents.
