A METHOD OF REMOVING HEMP BAST PECTIN USING MICROORGANISM

摘要

A method for refining a hemp bast fiber is provided to remove pectin from the hemp bast fiber effectively, by using commensal microorganisms having performances of degrading pectin of the hemp bast fiber. A heating cable(120) for supplying heat is installed at a reactor tank(100). An injection pipe(130) is installed on a bottom surface within the reactor tank, wherein the injection pipe has plural injection nozzles(132). An outside air compressor(140) is connected to the reactor tank. A hemp bast fiber is submerged in a commensal microorganism culture fluid(110) within the reactor tank. The commensal microorganism culture fluid and the hemp bast fiber are stirred for 24-36 hours so that pectin of the hemp bast fiber is used and removed as feed for commensal microorganisms. Herein, a temperature of the reactor tank is maintained at a temperature of 25-30°C by the heating cable and oxygen is intermittently injected to the culture fluid by injection nozzles of the injection pipe. The commensal microorganism is White-rot fungus, Blue-green algae or Micrococcus roseus.
