Abstract: Processes are disclosed for preparing microorganism concentrates from fermentation broth containing a free suspension of the microorganisms which is used for the anaerobic conversion of syngas to oxygenated organic compound. The processes involve the use of processing steps and the presence of certain additives to enhance the ability of the microorganism concentrate to be stored for extended periods and reactivated.

Abstract: The present invention relates to novel compounds capable of modulating the stability and/or activity of hypoxia inducible factor (HIF) by inhibiting the activity of at least one HIF hydroxylase enzyme.

Abstract: Ethanol and other liquid products are produced by contacting syngas components such as CO or a mixture of CO2 and H2 with a surface of a membrane under anaerobic conditions and transferring these components in contact with a biofilm on the opposite side of the membrane. These steps provide a stable system for producing liquid products such as ethanol, butanol and other chemicals. The gas fed on the membrane's gas contact side transports through the membrane to form a biofilm of anaerobic microoganisms that converted the syngas to desired liquid products. A liquid impermeable layer of the membrane assists in establishing direct gas phase contact syngas components with the microorganisms. The system can sustain production with a variety of microorganisms and membrane configurations.

Abstract: The invention relates to cells and a method for producing acetone.

Abstract: The present method describes the use of thio-phosphate as a feed source for micro-organisms and multi-cellular organisms. This compound enters into nucleotide pools and ultimately into polymers of both RNA and DNA forming stable phosphorothioate internucleotide linkages. The method enables the microbial synthesis of both plasmid and phage DNA substituted with phosphorothioate. Furthermore, methods are described for the preparation of phosphorothioate oligo mixtures from recombinant phage DNA grown in modified media for use in antisense studies.

Abstract: The thin film transistor has a non-transparent structure besides and insulated with the gate. Hence, the light transmitted from the substrate is blocked and the light current induced in the thin film transistor is negligible. The method uses a mask with a slit pattern to form a non-uniform photoresist. Hence, the mask could be used to pattern two conductor layers for forming source/drain/channel.

Abstract: Butanol and acetone are major end products of a bacterial fermentation process carried out by anaerobic saccharolytic clostridia such as Clostridium acetobutylicum. However, these organisms degenerate upon repeated subculture of growing cells, thereby losing their capacity to produce solvents and to develop into spores. A novel class of degeneration-resistant mutants of C. acetobutylicum, generated by transposon insertion mutagenesis, has been produced employing a novel selection procedure. Upon subculture the mutant cells survive significantly longer than the parental cells without altered solventogenic characteristics. The mutant organism, the technique for its isolation and its use are provided.

Abstract: A novel peroxidase was obtained from a fast growing microorganism of the genus Coprinus cinereus. The fungal peroxidase is comparable to the conventional peroxidase derived from horseradish or Japanese radish in that it can be used either as a clinical or diagnostic reagent or as a marker enzyme in enzyme immunoassay.

Abstract: A method of producing magnetite is disclosed which comprises culturing a microorganism designated GS-15 in the presence of organic matter and a ferric iron compound. Unlike prior art production of magnetite using magnetotactic bacteria, GS-15 is able to produce large amounts of ultrafine-grained magnetite extracellularly under anaerobic conditions, allowing for easy separation and recovery of the magnetite without the need for rigorous control over oxygen tensions in the culture medium. As a result, the method of the present invention can be used to mass produce magnetite efficiently using inexpensive means and materials.

Abstract: A method for producing butanol by fermentation is provided. The method is carried out by culturing a butanol-producing microorganism in a culture medium containing a fluorocarbon selected from the group consisting of monofluorotrichloromethane, monofluorodichloromethane, monochloroheptafluoroethane, dichlorodifluoromethane, dichlorotetrafluoroethane and mixtures thereof in an amount sufficient to increase butanol production, and by separating the butanol from the culture medium.
