KnipBio Announces Significant Development in Lower-Cost Feedstock Solution for Aquafeed Protein
submitted 5 months, 1 week ago by knipbio

KnipBio, Inc. announced today a major development in its fermentation research
that enables the company to produce its single cell protein aquafeed ingredient, KnipBio Meal
(KBM), from condensed distillers’ solubles (CDS). This promises a dramatic reduction in cost
and further demonstrates the versatility of KnipBio’s biotech platform and fermentation
According to Larry Feinberg, CEO of KnipBio. “CDS is a residual byproduct of ethanol
fermentation which until now has had limited economic value. Using CDS dramatically reduces
our feedstock costs, allowing KnipBio Meal to be competitively priced with traditional aquafeed
proteins. CDS is cheap, there’s a lot of it, and because it is a waste stream, it is inherently
sustainable with virtually no environmental footprint. Importantly, the composition analysis
indicates KBM derived from CDS has a protein content equal or greater than fishmeal and
contains none of the anti-nutritional factors often found in plant proteins. This makes it a
potential game changer for the aquaculture industry, which will now have access to an
affordable, sustainable, and traceable alternative to fishmeal and soybean meal. With this
product we are helping to expand the industry by diversifying the basket of proteins that can be
used in aquafeeds.”
Feinberg added, “The economics of producing KnipBio Meal from CDS are truly compelling. The
global biofuels industry produces more than 2.5 million tons of CDS each year as a byproduct of
ethanol fermentation. This CDS sells for about $100 per ton and is typically sprayed on animal
feed. When the same CDS is upcycled to produce KnipBio Meal, the resulting single cell
proteins sells for significantly more.”
KnipBio began the development of its patented, single cell fermentation process using methanol
in 2013. To reduce input costs and increase feedstock flexibility, the company initiated a
research program in 2018 to produce protein using low-cost feedstocks including CDS and
other biofuel waste stream products. Feedstock flexibility ensures supply security and price
stability. It also makes KBM more sustainable and allows a KBM fermentation plant to be colocated wherever industrial agriculture and food processing is done.
Feinberg stated, “Today’s announcement is the first result from our feedstock diversification
efforts. Now that we have succeeded in upcycling CDS, we are shifting from laboratory research
to commercialization and scale-up work has already begun. Additionally, results from initial
animal feed tests indicate KnipBio Meal is an excellent protein source for both fish and
crustaceans. While I expect continued challenges as we progress, we are confident we will
achieve our goals.”
