ABSTRACT:
The present invention relates to a biopulping method, and more particularly to a biopulping method for non-woody fiber plants. A biopulping method for a non-woody fiber plant is provided. It includes steps of providing a culture solution, adding a non-woody fiber plant to the culture solution, adding a microorganism suspension to the culture solution, fermentatively culturing the culture solution for preparing a pulp solution, boiling the pulp solution, pulping the pulp solution, and screening the pulp solution for isolating the paper pulp from the pulp solution.
