SUSFEED – Sustainable Fish Feed from Mixed Gas Fermentation (FS036)

Aim:

SUSFEED will provide new technologies for the generation of sustainable fish feed products for aquaculture, produced via mixed microbial fermentation from inexpensive mixed and/or waste gas streams.

Funding Amount:

£50,000

Duration of Project:

3 Months

Project Outcome:

In this 3-month feasibility study, scientists and engineers at CPI have worked together to improve the carbon efficiency and sustainability of Single Cell Protein production from gas fermentations, for the aquaculture industry. 

Current aquaculture feed is manufactured mainly from agricultural products and fish meal. To produce 1kg of fish more than 2kg of fish meal is required which makes it a very unsustainable source of fish feed; while soy and grain-based feeds can result in poor digestibility by fish, and inefficient use of natural resource such as arable land and water, required to produce them. SUSFEED aims to provide a new technology for the generation of sustainable fish feed products for aquaculture, produced via mixed microbial fermentation from inexpensive mixed and/or waste gas streams.

In this feasibility study the initial proof of concept of utilising mixed gas streams to grow mixed cultures of bacteria has been successfully demonstrated. This paves the way to a follow-on programme which will further investigate the capacity and the economy of this technology in an industrial relevant environment and scale up to produce enough biomaterials for a fish feed trial.
