摘要:
An improved method for the degradation of haloaliphatic compounds using induced cells of sulfate reducing anaerobic bacterium, particularly Desulfomonile tiedjei, is described. The cells are induced using 1,3-substituted phenyl compounds, particularly 3-halobenzoates, such as 3-fluorobenzoate which are gratuitous inducers and thus are not dehalogenated. The result is a much more rapid dehalogenation of the haloaliphatic compounds than was achieved by prior art methods using uninduced cells.
摘要:
The present invention provides compositions providing and methods using fluorescence detection device, comprising an electroluminescent light (EL) source, for measuring fluorescence in biological samples. In particularly preferred embodiments, the present invention provides an economical, battery powered and Hand-held device for detecting fluorescent light emitted from reporter molecules incorporated into DNA, RNA, proteins or other biological samples, such as a fluorescence emitting biological sample on a microarray chip. Further, a real-time hand-held PCR Analyzer device comprising an EL light source for measuring fluorescence emissions from amplified DNA is provided.
摘要:
A process for producing hydrogen anaerobically in a culture medium or in the environment using a proteobacteria is described. Preferably the proteobacteria is Desulfovibrio sp. ATCC 55738 (FOX1). The hydrogen can be used as a fuel and for other purposes and is a staple chemical.

摘要:
Substantial degradation of polychlorinated biphenyl (PCB) mixtures is carried out using the white rot fungus Phanerochaete chrysosporium, under nutrient, carbon and nitrogen source rich, non-ligninolytic conditions. The PCBs with various numbers of ortho, meta, and para chlorines were extensively degraded, indicating relative nonspecificity for the position of chlorine substitutions on the biphenyl ring. Maximal degradation of PCBs in a mixture was observed in malt extract medium (18.4% on a molar basis), in which most of the individual PCBs were degraded.
