Single cell proteins are gathering some interest for what they can offer producers seeking alternatives to more traditional proteins like soybean meal.
Researchers in Finland have been working on a way to generate its single-cell protein biomass using a combination of electricity and carbon dioxide. It could potentially mean that the feed ingredient would be producible anywhere that renewable energy is used.
In another use of single cell proteins, researchers in Mexico examined the potential for torula yeast as a protein alternative for fishmeal in shrimp diets. Similarly, in Norway, researchers examined the of yeast derived from non-edible lignocellulosic biomass for use in fish and piglet diets.
