摘要： A chemical sensor and a system and method for sensing a chemical species. The chemical sensor includes a plurality of nanofibers whose electrical impedance varies upon exposure to the chemical species, a substrate supporting and electrically isolating the fibers, and a set of electrodes connected to the plurality of fibers at spatially separated points to permit the electrical impedance of the plurality of fibers to be measured. The system includes the chemical sensor, an impedance measuring device coupled to the electrodes and configured to determine an electrical impedance of the plurality of fibers, and an analyzer configured to identify the chemical species based on a change in the electrical impedance. The method measures at least one change in an electrical impedance between spatially separated electrodes, and identifies the chemical species based on the measured change in the electrical impedance.

摘要： The present invention provides a mutant strain of Bacillus subtilis SFA-H31 and includes an optimized method for producing of acetoin using this strain. The advantage of this method to produce acetoin has been defined by its high-yield without mixture with diacetyl or 2,3 butanedinol, both of which are usually accompanied with acetoin in other strain. This Bacillus subtilis mutant strain has been deposited in China General Microbilogical Culture Collection (CGMCC) and the accession number is CGMCC No. 1869, in which the process of fermentation for acetoin production is composed of (1) strain activation, (2) seed culture, (3) fermentation, (4) quantification of substrates and products. Based on current method, the concentration of acetoin in the ferment broth can reach to 35-55 g/L and the conversion rate of glucose to acetoin is in the range of 40-50%.
