摘要:The present invention refers to a method for the synthesis of an adsorbing material consisting of a single-phase tetravalent manganese feroxyhite (Å?-Fe (1-x) Mn x OOH), in which a percentage of 0.05 to 25% of iron atoms has been isomorphically substituted by Mn(IV) atoms. Its production takes place in a continuous two-stage flow reactor at weakly acidic conditions (pH 4-7) and high redox (300-800 mV). The material can be used for the removal of both pentavalent and trivalent arsenic as well as other heavy metals form water. More specifically, its adsorption capacity and selectivity depending on the trivalent and pentavalent arsenic water content, are determined by the manganese percentage and the compact or hollow morphology of its structural unit which can be both controlled by the parameters of the synthesis procedure.

摘要:The present invention relates to a method for promoting acetylglucosamine synthesis of Bacillus subtilis, which belongs to the field of genetic engineering. The present invention adopts the recombinant Bacillus subtilis BSGNKAP2 as a starting strain, exogenously introducing pyruvate carboxylase BalpycA derived from Bacillus cereus, eliminating the central carbon metabolism overflow of the Bacillus subtilis and avoiding the synthesis of the by-product acetoin; further, five exogenous reducing force metabolic reactions are introduced to replace the reaction of generating NADH in glycolysis pathway and tricarboxylic acid cycle to reconstruct intracellular reducing force metabolism, which specifically comprise glyceraldehyde-3-phosphate ferredoxin dehydrogenase, isocitrate NAD+ dehydrogenase, a malate quinone dehydrogenase, a ketoacid ferredoxin oxidoreductase and a nitrogenase ferritin. In a shake-flask fermentation process using a complex medium, acetylglucosamine yield of the recombinant strain BSGNKAP8 is 24.50 g/L, acetylglucosamine/glucose yield is 0.469 g/g, respectively 1.97 times and 2.13 times of those of the starting strain BSGNKAP2.

摘要:The present invention relates to a production apparatus for hydrothermal synthesis of lithium iron phosphate, which comprises first stirring devices, a preheating device, a second stirring device, and a drying device, wherein there are two first stirring devices, and the preheating device comprises a housing, a heating box, two feeding pumps, two first transfer assemblies, and several first heating tubes; the two first transfer assemblies each comprise an inlet pipe, an outlet pipe, and several transfer branch tubes. In the present application, the arrangement of multiple transfer branch tubes increases the heated area of the slurry, enhances the thermal conduction efficiency, and improves the heating effect. The equidistant arrangement of the transfer branch tubes ensures uniform heating of the slurry within the multiple transfer branch tubes, guaranteeing the heating effect. The arrangement of the preheating device can reduce the heating time of the slurry, thereby enhancing the heating effect.
