Abstract: Methods and processes for producing aerobic digestion products, such as organic acids, from a low-rank coal substrate are provided. Also provided are multistage bioreactor systems for carrying out the described methods and processes. In another aspect, product compositions comprising organic acids produced by the described methods and processes are provided, as well as methods for their use, including for the improvement of soil quality and/or plant growth.

Abstract: The present disclosure provides methods and systems for production of biostimulants that promote nitrogen use efficiency in plants. Embodiments described include methods of making a biostimulant composition in a bioreactor system that includes two or more containers arranged in series. The bioreactor system may include an established population of a nitrogen use efficiency-promoting microbial strain. The method may include operating the bioreactor system by transferring into the system an aqueous feedstock that comprises a microbial consortium, transferring working fluid between containers of the system, and collecting a product. The method may further include maintaining a concentration of a nitrogen use efficiency-promoting microbial strain in the system.

Abstract: A process wherein the use of a degradation-enhancing reactant or a precursor thereof, e.g., an oxidizing agent, can effectively increase the rate of reaction for the degradation of polymers in an aqueous environment and thereby facilitate the disposal of same. For example, in one aspect, the process comprises contacting a solubilized polymer and a degradation-enhancing reactant, within an aqueous environment, and subsequently reacting the polymer under conditions that are effective to provide at least one environmentally benign degradation product from the polymer.
