This paper reports a 40-day windrow composting trial in which a combined Aspergillus oryzae (koji mould) and Bacillus subtilis inoculant was added to beef cattle manure. The study tracked temperature, maturity and the load of pathogenic pro- and eukaryotic microorganisms through the composting cycle, and found the inoculant accelerated maturation and reduced the target pathogens.
Composting is the route by which a farm turns a wet, odorous manure stream into a stable, spreadable material. The two organisms in this study — a cellulolytic/amylolytic mould and a spore-forming bacterium — are exactly the kind of combined culture we formulate for livestock-manure fermentation and composting, so the work is a direct, peer-reviewed anchor for that product line.
Why this research is on our site
We present this work as foundational agricultural-microbiology research. It is not a product datasheet and it is not a performance claim for any commercial formulation — the trial used a specific inoculant ratio and a specific windrow protocol. What it gives our livestock product development is evidence that a combined Aspergillus oryzae + Bacillus subtilis culture can shift both the rate of manure maturation and the pathogen load, and a shared basis to discuss dosing and protocol with farm customers.

If you stabilise livestock manure before storage or composting and want a culture programme matched to your heap or store, we can review the protocol with you.
