Abstract: Disclosed is a method for preparing self-dispersing nano carbon black based on a thiol-ene click reaction. A sol-gel technique is used to graft a coupling agent containing a carbon-carbon double bond onto the surface of the carbon black, and a functional molecular chain is grafted onto the surface of the carbon black by a thiol-ene click reaction with a mercapto compound. The self-dispersing nano carbon black is obtained after centrifugation, washing and drying. The method is simple and easy to operate, has a high grafting rate, and can prepare self-dispersing nano carbon black adaptable to different systems by selecting mercapto compounds with different functional groups.

Abstract: High-yield antibiotics producing strain, preparation method and use thereof are provided in the present invention. The high-yield strain is a mutagenized strain derived from Colephoma empetri, and deposited in CGMCC with the accession number of CGMCC 4129. The preparation method comprises the following steps: (a) mixing a seed liquid of Colephoma empetri of Accession No. FERM BP-2635 with nitrosoguanidine to obtain a mixture a; (b) mixing said mixture a with a wall-breaking enzyme to obtain protoplasts; (c) regenerating said protoplasts to obtain single colonies; and (d) culturing said single colonies to obtain said mutagenized strain. The obtained strain has stable genetic and producing property, produces little impurities in fermentation, and is suitable for industrialization.
