Fungal pentose phosphate pathway bioconversion for high-value carbon sequestration from cereal crop waste
Novel aerobic bioconversion process using medicinal Oyster mushrooms to transform cereal crop lignocellulosic residues into high-value nutraceuticals, plant health extracts, probiotics, and soil amendments—delivering complete biocircular carbon sequestration with net-zero residue.
Overview
This innovation leverages the pentose phosphate pathway of medicinal Oyster mushrooms to aerobically bioprocess lignocellulosic-rich cereal crop residues into a complete biocircular carbon recycling system. Cereal crop residues contain over 50% of the total carbon sequestered in U.S. agriculture, yet without efficient recycling they contribute to an increased carbon footprint. By coupling fungal aerobic respiration with the anabolic pentose phosphate pathway, this approach generates multiple high-value product streams: nutraceutical-rich mushrooms for human health, soluble phenolic and amino acid extracts for plant health, and insoluble residues for soil health. The result is a net-zero carbon residue process that connects agricultural waste to human nutrition, organic agriculture, and climate-resilient farming.
Technical specifications
Key features:
- Solid-state bioconversion of cereal lignocellulosic residues using chitosan-rich medicinal Oyster mushrooms
- Proprietary organic addendums with amino acid-coupled aerobic metabolism to drive pentose phosphate pathway activity
- Multi-stream product output: whole mushrooms for nutraceuticals, liquid extracts (cold and hot) for plant growth and seed treatment, phenolic and amino acid extracts for Lactic acid bacteria-based agro-inoculants and human probiotics, and solid residues for urban agriculture potting mix
- Complete biocircular carbon flow linking human, plant, and soil health applications
- Builds on validated fungal bioconversion precedents with fruit, cranberry, soybean, and fava bean residues
Technology readiness level
The underlying solid-state bioconversion approach has been previously validated across multiple agricultural residue types, demonstrating the capacity of fungi to generate multiple value chains from lignocellulosic substrates. Current work targets novel medicinal Oyster mushroom strains and proprietary organic addendums specifically optimized for cereal crop residues, with planned validation of the full product stream—from nutraceutical mushrooms to plant health extracts, probiotics, and soil amendments. The process is positioned for pilot-scale demonstration and further development toward commercial deployment in agricultural and nutraceutical markets.
