Yarrowia Equinox is a trademark owned by Skotan – joint-stock company, listed on the Warsaw Stock Exchange since 2006. For several years, the company has been implementing research and development of the projects in the feed, pharmaceutical and green energy sectors.

Currently Skotan S.A. focuses on the comprehensive commercialization of research projects in the field of Yarrowia lipolytica yeast and Essential Unsaturated Omega-3/6/9 Fatty Acids Ethyl Esters production. These materials form the basis for all products dedicated to horse nutrition.

Skotan S.A. for years has been carrying out research projects together with recognized scientific centers in Poland, including the University of Environmental and Life Sciences in Poznan, Lublin and Wroclaw, the University of Agriculture in Krakow, the State Veterinary Inspectorate in Puławy, the Institute of Immunology and Experimental Therapy of the Polish Academy of Sciences in Wrocław and the Institute of Horticulture in Skierniewice.

The mission and main goal of the company is to provide innovative feeds and dietary supplements of high quality for animals, support the treatment of diseases, improve the condition and support animal owners in achieving good sport and breeding results.


Yarrowia lipolytica is a dimorphic yeast forming creamy, irregular colonies with numerous hyphae. These yeast naturally occur in margarine, cereal plants, meat products with high protein content, vegetables, frozen food and wines.


Yarrowia lipolytica yeast belong to non-pathogenic microorganisms, and are involved in processes with Generally Recognized as Safe (GRAS) status. These yeast, unlike Saccharomyces cerevisiae yeast processing simple carbohydrates, use fats (vegetable fatty acids, including unsaturated acids) as a source of carbon and energy.

The unique Yarrowia lipolytica yeast strain, included in Yarrow Equinox, was selected from numerous strains tested during research. Extremely high biomass production efficiency and considerable tolerance to harsh culturing conditions, such as increasing osmotic pressure and relatively low pH of the medium, were achieved. As a result, biomass with very high nutritional values was obtained.

This strain, thanks to its unique physiological and biochemical properties, has a huge potential in biotechnology.
