Abstract: The present disclosure relates to the technical field of biotechnology renewable energy, and more specifically, to a method for producing citric acid by degrading roughage with natural symbiotic mixed culture. The mixed culture YakQH5 is composed of anaerobic fungi (Neocallimastix frontalis) and methanogens (Methanobrevibacter gottschalkii). It was collected in the China General Microbiological Culture Collection Center on Mar. 9, 2020, with the collection number of CGMCC No. 19299. The mixed culture YakQH5 can degrade 15 kinds of roughage respectively and produce a large amount of citric acid. Especially when alfalfa is used as substrate, the yield of citric acid is as high as 46.0 mm. Adding compound antibiotics in the fermentation process can also prevent the mixed culture from being polluted by bacteria in the fermentation process and further improve the efficiency of anaerobic fermentation. The mixed culture YakQH5 has important industrial application value.

Abstract: A permanent magnet motor has a number of permanent magnets forming permanent magnet poles. Each magnet has an outer surface that is an arc surface with a convex middle. An inner surface of the magnet is a curved surface with a concave middle. The curved surface has an arc surface section and two planar surface sections.

Abstract: A commutator has a conductive layer, a segment layer and an insulating layer separating the conductive layer and the segment layer. The segment layer includes multiple commutator segments. A mounting hole is defined along an axis of the commutator passing through the conductive layer. The three-layer structure of the commutator forms a capacitor having an increased confronting area and reduced inter-plate distance. The capacitor thus has a greater capacitance and hence greater EMI absorbing capability, making it possible to reduce EMI emissions without additional EMI reduction components outside the commutator. A rotor and a motor employing the commutator are also disclosed.
