Mixotrophic Fermentation

White Dog Labs continues to invent and develop strategies that harness the ability of special microorganisms to simultaneously consume carbohydrates and gases to efficiently produce metabolites at improved yields. The scientific name for our approach is Anaerobic, Non-Photosynthetic Mixotrophy or just a Mixotrophic Fermentation. The detailed theory and technical opportunities can be found in several of our recent publications.

Importantly, this is a platform technology capable of producing a wide-range of MixoFerm™ products from direct petrochemical replacements (such as acetone and isopropanol) to novel bio-advantaged molecules to animal feed products (for example, ProTyton™). What sets our MixoFerm™ products apart from similar bio-based products is the enhanced carbon yields of our products and the corresponding lower carbon intensity scores of them.

In traditional fermentation, the maximum carbon yield for the majority of biochemicals is about 65%. However, White Dog Labs’ MixoFerm™ products have a carbon yield of at least 70%. This is due to CO2 reassimilation during the fermentation and results in improved yields for the MixoFerm™ product and a lower carbon intensity score. If higher carbon yields are required, White Dog Labs offers MixoFermPlus™ products that have a carbon yield of at least 85%. This is achieved by adding a reducing gas to the fermentation and results in even greater CO2 reassimilation and higher carbon yields. For certain products, like ethanol, we have been able to fully eliminate CO2 emissions from the fermentation process to yield our Zero-CO2 Ethanol™. We currently offer samples of MixoFerm™ Acetone and MixoFermPlus™ Isopropanol to interested customers and can generate additional biochemicals of interest upon request.
