Cargill is expanding its offerings of sustainable alternatives to fishmeal in aqua feed thanks to a new agreement with White Dog Labs. The deal secures access to ProTyton™, White Dog Labs' single-cell protein produced by fermentation with corn feedstock—a sustainable alternative to harvesting fishmeal—which, like fishmeal, is high in protein and amino acids. ProTyton™ will be ready to ship from White Dog Labs' demo facility in Sutherland, NE in 2020.
