1. A method for producing a microbial growth stimulant solution from a lignocellulosic plant biomass comprising:

  • providing a harvested lignocellulosic plant biomass;

    treating the plant biomass with an Ammonia Fiber Explosion (AFEX) process to provide a treated plant biomass;

    soaking the treated plant biomass in an alkaline aqueous solution of ammonium hydroxide at 25°

    to 70°

    C. to provide a soaked plant biomass in the solution;

    extracting the solution from the soaked plant biomass to produce an extracted solution;

    separating at least some of the proteins and ammonia from the extracted solution; and

    retaining the extracted solution as the microbial growth stimulant solution.
