The University of Maine Forest Bioproducts Research Institute and Aquaculture Research Institute have been awarded a $10 million grant from the U.S. Department of Agriculture to investigate the potential of wood as a component for aquafeeds and biofuels.
Aquafeeds often contain significant amounts of fishmeal and fish oils which are both ecologically untenable and expensive for farmers to procure. Offering an attractive alternative to these traditional ingredients, the research conducted by the University of Maine, alongside several collaborators, suggests that the sugars found in woody biomass can be fermented into alternative proteins for aquafeeds.
“The Aquaculture Research Institute (ARI) is thrilled to be part of this groundbreaking project,” said ARI Director Debbie Bouchard, in a press release.
“By converting low-quality wood into an ingredient for sustainable fish feed, we’re not only addressing a critical need in aquaculture but also enhancing the economic value of Maine’s forests. This innovative approach will pave the way for more resilient and sustainable aquaculture practices.”
The sugars, lignin and other biomass components from the wood will be separated by the researchers and converted to protein through a microbial fermentation process. The proteins will then be formulated into experimental aquafeeds which will be used in salmon growth and digestibility studies.
Lignin and other byproducts of the sugar production will be processed into sustainable aviation fuels.
