1. A process for producing a microbial growth stimulant solution from a lignocellulosic plant biomass comprising:
- (a) providing a harvested lignocellulosic plant biomass;
(b) treating the plant biomass with an Ammonia Fiber Explosion (AFEX) process to provide a treated plant biomass;
(c) extracting proteins in the treated plant biomass with an aqueous alkaline ammonium hydroxide solution comprising up to about 3% by weight NH4OH to provide the extracted proteins in the solution; and
(d) separating at least some of the proteins and part of the ammonia from the solution to thereby produce a microbial growth stimulant solution.

Abstract
A process for producing a microbial growth stimulant (MGS) from a plant biomass is described. An ammonium hydroxide solution is used to extract a solution of proteins and ammonia from the biomass. Some of the proteins and ammonia are separated from the extracted solution to provide the MGS solution. The removed ammonia can be recycled and the proteins are useful as animal feeds.
