This study uses sequential selective soil extractions to trace the fate of base cations released during microbially accelerated silicate weathering. This work validates Andes' CDR approach and confirms that soil inorganic carbon (SIC) measurements are a robust and necessary method for verifying carbon removal. The preprint is available through the CDRXIV preprint repository and can be downloaded here. https://images.squarespace-cdn.com/content/v1/57a7b2f8f5e231cfd157e7fc/ba15a198-f2e3-43ea-afd0-e249e0ba29df/Yip+2026.png Scientific Papers - Bacillus subtilis MP1-mediated weathering of basalt revealed through sporulation This manuscript has been submitted for peer review. This study establishes bacterial sporulation as a novel biosensor for silicate weathering. The research demonstrates that Andes’ Bacillus subtilis strains MP1 and MP2 actively accelerate basalt dissolution to access essential metals required for spore formation. Using a sporulation-deficient mutant (ΔspoIIE), the work provides robust evidence that microbial activity, rather than abiotic processes alone, drives silicate dissolution, validating a new physiological proxy for monitoring the efficiency of microbially-accelerated silicate weathering.

Led by Dr. Cody Madsen (LLNL), the research demonstrates how Andes’ microbial amendment strains (Bacillus subtilis MP1 and MP2) not only weather minerals directly but also restructure native microbial communities to enhance dissolution rates. By identifying specific bacterial genera associated with improved weathering, this work establishes a framework for engineering soil microbiomes to advance soil health and carbon drawdown strategies. The preprint will be available soon. https://images.squarespace-cdn.com/content/v1/57a7b2f8f5e231cfd157e7fc/5a87c868-9edf-43fe-abe6-8875f82f3f50/Timmermann+2025.png Scientific Papers - Harnessing Microbes for Scalable Carbon Dioxide Removal in Agricultural Soils Published in Global Change Biology Led by Andes’ CTO and Co-Founder, Dr. Tania Timmermann, this foundational paper validates our core carbon dioxide removal (CDR) technology. Through a comprehensive suite of in vitro assays, mesocosm studies, and field trials, we demonstrate how Andes’ beneficial microorganisms accelerate the weathering of native soil silicates. The result is measurable, permanent carbon dioxide removal that integrates seamlessly into existing agricultural systems.

It investigates how co-applying Andes’ proprietary microbial strain (MP1) with crushed basalt significantly enhances carbonate alkalinity while preserving soil organic carbon. Conducted in a soybean mesocosm system, this research is a critical step toward developing scalable, hybrid Carbon Dioxide Removal (CDR) strategies that integrate soil microbiology with enhanced rock weathering.

Led by Dr. Chris Yip and Dr. Phil Weyman, this work introduces a novel, high-throughput gas chromatography technique for quantifying inorganic carbon. This method delivers exceptional precision for both solid soil and pore water samples, setting a new standard for measurement, reporting, and verification (MRV) in soil carbon projects.

By modeling the geochemistry of the soil mesocosms, we constrained the kinetics of the weathering process. The study confirms that the formation of secondary minerals (calcium carbonates) acts as a "sink" for weathering products, preventing saturation and allowing the weathering process to continue at accelerated rates. Key Findings: Modeling Validation: The reactive transport model successfully reproduced the temporal evolution of leachate pH and cation concentrations observed in the physical experiments. Coupled Processes: The model identified that anorthite (calcium-rich feldspar) weathering coupled with secondary calcite formation is the primary driver of the observed carbon removal. Rate Quantification: Simulations that best matched the experimental data indicated that the anorthite weathering rate constant in MP1-treated soils was roughly 10 times higher than the baseline. Carbon Dioxide Removal (CDR): The model simulations were consistent with experimental estimates of CDR based on soil inorganic carbon measurements. https://images.squarespace-cdn.com/content/v1/57a7b2f8f5e231cfd157e7fc/d1ee00cc-8a45-4e37-bb11-23f7f92b0b8f/2025_AGU_Timmermann_v1.4a.png Scientific Conferences - Harnessing Microbes to Weather Native Silicates in Agricultural Soils for Scalable Carbon Dioxide Removal AGU 2025 - New Orleans, LA, USA This study provides a comprehensive look at how Andes' beneficial microorganism, Bacillus subtilis strain MP1, accelerates the natural silicate weathering process. The research spans from in vitro laboratory characterization to mesocosm studies and large-scale field trials. The results demonstrate that MP1 forms biofilms on mineral surfaces, creating specific microenvironments that significantly accelerate the release of base cations and the subsequent precipitation of stable carbonates. Key Findings: Mechanism: MP1 forms robust biofilms on feldspar surfaces, generating a low pH microenvironment at the mineral interface for dissolution and a high pH environment at the biofilm surface for carbonate precipitation. Accelerated Weathering: In controlled soil columns, MP1 enhanced the native silicate weathering rate by over 6 times compared to untreated controls. Carbon Storage: Soil Inorganic Carbon (SIC) increased by 20% in MP1-treated soil columns. Field Performance: In a large-scale trial across 847 hectares in North Dakota, MP1 treatment resulted in a gross accrual of 2.02 tonnes of inorganic Carbon per hectare annually. Agronomic Benefits: Soybean grain yield increased by 7.5% (0.21 tonnes/ha), and soils showed improved pH buffering compared to controls.
