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%.

摘要： A juice extraction module for a large-caliber juicer includes a base, a hood body, a rotary brush, a juicing net and a helical structure, wherein the hood body is matched with the base; the rotary brush, the juicing net and the helical structure are accommodated in a housing formed by matching the base and the hood body; the helical structure is accommodated in the juicing net; the juicing net is accommodated in the rotary brush and an outer wall of the juicing net is fitted with an inner wall of the rotary brush. An extrusion part is arranged on the helical structure of the juice extraction module for the large-caliber juicer in the utility model. Helical vanes are arranged at the periphery of the extrusion part. Outer diameters of the helical vanes are consistent from top to bottom. A cutting part is arranged at a top of the extrusion part. The cutting part firstly cuts fruits and vegetables into small blocks; the helical vanes continuously deliver the small blocks of the fruits and vegetables downwards and extrude the small blocks, so as to realize quick juicing, thereby effectively preventing the fruits and vegetables from accumulating in a feed inlet and increasing juicing efficiency.
