A salmon feed developed by String Bio, a company developing feed ingredients from greenhouse gases, has been validated by the global aquafeed maker BioMar.

String Bio of India announced this week that its animal nutrition product – PRO-DG has been successfully tested and validated by BioMar for use “across various species in different geographies and varying farm management practices.” The product also provides traceability, significantly optimizes the use of land and water, and provides sustainability to the feed value chain.

String Bio said that BioMar paid particular attention to the evaluation of this new unicellular protein, which they have been working on for some time together with String Bio. The intention of biologically evaluating the product, calculating its value in diets, and trying to help the process of commercial acceleration of this interesting new raw material.


“It’s a great milestone to have the validation studies done by Biomar, an industry leader in the Aqua nutrition sector,” said Dr. Ezhil Subbian, co-founder and chief executive officer of String Bio. “We look forward to taking the work ahead with them to drive commercial adoption of novel ingredients in aquaculture.”

“The preliminary results of the validation highlight the biological potential of PRO-DG as a protein alternative within our current basket of raw materials to reduce carbon emissions”, said Fernando Norambuena, BioMar’s global category manager for novel raw materials.

String Bio focuses in gas fermentation, scaling up economical and modular fermenters that enable the production of high-quality ingredients from greenhouse gases.

PRO-DG is an alternative protein ingredient with optimal nutritional factors, manufactured by the platform.

Key performance and physiological parameters from the trials validated the use of PRO-DG as a feed ingredient in salmon diets, the company said. In previous trials with renowned institutes, PRO-DG has been found to increase feed conversion and growth rates in shrimp, poultry and other species as well.
