摘要:
Methods and systems for producing lipids which may be used as biofuel are provided. Sugars produced by pretreatment of lignocellulosic biomass are utilized by heterotrophic oleaginous fungi or yeast to increase their biomass and to produce lipids without prior detoxification of the pretreated biomass. After the fungi/yeast are cultured with the sugars, solid residues from the pretreated biomass are combined with the fungi/yeast under conditions which allow simultaneous 1) enzymatic degradation of cellulose and/or hemicellulose to produce sugars and 2) fermentation of the sugars for further increases in biomass and lipid production.

Various embodiments of contaminant removal systems, compositions, and methods are described herein. In one embodiment, a method for oxidizing a contaminant includes contacting the contaminant with a peroxygen compound and initializing, maintaining, or propagating degradation of the peroxygen compound with an oxygenated organic compound, thereby releasing oxidizing radicals. The method also includes oxidizing the contaminant with the released oxidizing radicals.

Low cost, efficient two-stage anaerobic digestion systems for the production of biogas (e.g. methane) are provided. During the first stage, biogas is produced in a first reactor by anaerobic microbes cultured in two phases: a high solids phase and a low solids phase. During the second stage, biogas is produced in a second reactor by a methanogen-rich anaerobic culture cultured in low solids medium. Removal of effluent comprising pH lowering reaction products assists in maintaining a suitable pH in the high solids phase. The transfer of effluent from the second reactor to the first reactor assists in maintaining a suitable pH in the high solids phase, in mixing of the high solids phase, and in reseeding the high solids phase with methanogens. Methane is produced in and recovered from both reactors.

Particular aspects provide novel recombinant cells and cell lines (e.g., macrophage cell lines) that are permissive for propagation of porcine reproductive and respiratory syndrome virus (PRRSV) propagation in vitro or in vivo. In certain aspects, novel nucleic acid sequences encoding porcine sialoadhesin were transfected into existing macrophage cell-lines from other species, rendering them permissive to PRRSV infection, and suitable for propagation of PRRSV. Particular aspects provide exemplary recombinant cloned cell lines that support the replication of PRRSV, with an obtainable PRRSV titre of between 2×105/ml and 2×106/ml. Additional aspects provide novel nucleic acid sequences and polymorphisms thereof that encode for porcine sialoadhesin. Further aspects provide PRRSV propagation and preparation methods using the novel recombinant cell lines, and methods for PRRSV antigen and vaccine production using same. Yet further aspect provide transgenic, chimerical or engrafted animals having cell comprising nucleic acid sequences encoding porcine sialoadhesin.

摘要:
The cell surface c-Met receptor, through which hepatocyte growth factor (HGF) signals are mediated, has now been identified as the Angiotensin-IV receptor (AT(4)R) in processes that include HGF-regulated cell motility, angiogenesis, cancer metastasis, adipogenesis and others. Disclosed are angiotensin-like factor compositions and methods for using them to diagnose, prevent and/or treat conditions associated with c-Met dysregulation, including cancer, obesity and conditions associated with obesity, and other disorders, for example, by altering hepatocyte growth factor activity or c-Met receptor activity by administering an angiotensin-like factor that specifically binds to a cell surface c-Met receptor.

Disclosed herein are methods for improving fruit production or fruit quality in fruit trees, such as decreasing cold damage, increasing fruit size, increasing fruit quality, and/or increasing fruit set. In some embodiments, the disclosed methods include methods of decreasing cold damage to a fruit tree including applying an effective amount of a composition including DL-β-aminobutyric acid to the fruit tree, thereby decreasing cold damage, for example as compared to a control. In other embodiments, the disclosed methods include methods of increasing fruit size or fruit quality of fruit from a fruit tree, including applying an effective amount of a composition including prohexadione-calcium to the fruit tree after anthesis, thereby increasing fruit size or fruit quality, for example as compared to a control. In further embodiments, the disclosed methods include methods of increasing fruit size of fruit from a fruit tree or increasing fruit set of a fruit tree including applying an effective amount of a composition including 4-chlorophenoxyacetic acid to the fruit tree, thereby increasing fruit size or fruit set, for example as compared to a control.

摘要:
A vortex-stabilized electrophoretic processor comprises an annular processing chamber at least partly defined by concentric first and second processing chamber surfaces. At least one of the processing chamber surfaces is rotatable relative to the other processing chamber surface. The electrophoretic processor further comprises an electric field generator operative to be energized to establish a dynamic field gradient within the processing chamber. At least one fluid port is provided, having fluid communication with the processing chamber. The electric field generator may comprise an elongate electrode array positioned within a central bore of a rotor forming the inside surface of the processing chamber. One or both of the processing chamber surfaces can have shaping comprising multiple spaced tines or annular ridges extending toward the other of the processing chamber surfaces.
