Cargill and White Dog Labs work together to scale up production of single-cell protein feed

Agreement secures production of White Dog Labs’ ProTyton in salmon feed, ready to ship from 2020.

In a press release, feed giant Cargill writes that it is expanding its offerings of sustainable alternatives to fishmeal in aquafeed 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.

Last October, the US-based White Dog Labs (WDL) signed a collaboration agreement with Midwest Renewable Energy (MRE) to locate its first ProTyton plant within Midwest Renewable Energy’s ethanol site in Sutherland, Nebraska.

White Dog Labs is one of a wave of labs who are developing sources of protein from cells of microorganisms such as yeast, fungi, algae, and bacteria, which have less of a burden on the environment.

ProTyton will be ready to ship from White Dog Labs’ demo facility in Sutherland, NE in 2020.

“This agreement underlines our commitment to sustainable aquaculture and discovering new and strategic ingredients that will help feed the world in a safe and responsible way,” said Cargill’s president of its aqua nutrition business Adriano Marcon. “ProTyton offers a good source of protein for fish and shrimp, an affordable feed ingredient for farmers and a sustainable option for the planet that lessens our reliance on fishmeal—which we know to be a finite resource.”

Cargill plans to begin offering ProTyton in salmon feed as White Dog Labs’ production volume increases. “In trials, salmon fed a diet containing ProTyton achieved a growth performance comparable to salmon on a conventional diet,” Cargill wrote.

“We’re honoured to partner with Cargill to lead the industry in the application of highly scalable, alternative proteins for aquaculture,” said White Dog Labs CEO Bryan Tracy.

Cargill’s announced partnership with White Dog Labs follows its June 24 announcement of a strategic partnership with InnovaFeed to scale up and jointly market fish feed made with insect protein.
