With our growing world population we are placing Earth’s natural resources under severe pressure. One of our most pressing challenges will be to feed everyone a balanced and nutritious diet while keeping our effects on the environment to a minimum.

Microbial single cell protein as an ingredient for animal feed. A sustainable alternative animal feed ingredient, turning methane gas into high quality protein

Aqua-Spark’s first investee is US-based biotechnology company Calysta, which could transform fish feed – making it healthier and more environmentally sound.

Calysta, Menlo Park, CA, is an innovator in sustainable industrial products for food and energy security. Calysta has two business units. Calysta Nutrition develops and commercializes fish and livestock nutritional products. Calysta Energy is developing high value materials for use in industrial and consumer products.
Until now, feed has involved everything from chicken to wild-caught fish, ultimately defeating the purpose of farming fish. Calysta cultivates an efficient, methane-eating natural microbe that produces protein. This is a new and sustainable feed ingredient – a single cell protein that is a perfect replacement for fishmeal.
