Yarrowia Equinox is a line of products for horses, based on the unique properties of Yarrowia lipolytica yeast and a unique composition of fatty acid bioesters. The Yarrowia Equinox line includes preparations that aid digestion, improve the condition or have a positive effect on the condition of the coat. The unique Yarrowia lipolytica yeast strain used in Yarrowia Equinox has been selected from a number of strains tested in previous studies. Extremely favorable biomass production efficiency was achieved, as well as significant tolerance to unfavorable conditions of the cultivation process, such as increasing osmotic pressure and relatively low pH of the medium. As a result, a biomass with very high nutritional values ​​was obtained.
