Abstract Food waste (FW) to value-added application represents a demanding opportunity in the circular economy. As one of the approaches, FW hydrothermal carbonization (HTC) delivers an aqueous phase (HTC-AP), which would be suitable when applied to microbial growth and lipid production. In this context, this current work explored HTCAP from FW obtained through HTC (temperatures 200 to 260 degrees C) for microbial growth of 14 different Yarrowia species . Among these strains, Y. lipolytica, Y. keelungensis, Y. porcina, and Y. galii showed the ability to utilize HTC-AP. In HTC from 200 degrees C high optical density (OD 600 ) reaching above 1.2 for the 4 species was observed. An increase in the temperature by 20 degrees C declined the growth of Y. lipolytica, Y. porcina , and Y. galii by 17%. However, Y. keelungensis showed good growth regardless of the HTC temperature. Further, the lipid produced better at higher biomass 240 degrees C compared to 260 degrees C during the HTC. Further, Y. yakushimensis showed the highest growth rate among all the analyzed media (0.12 - for medium 2 (0.45 NH 4 + and 200 degrees C). Although the composition of HTC-AP is very diverse and often toxic, some analyzed yeast species can use the contained compounds as a carbon source for biomass and lipid biosynthesis. The presented possibilities are a very good starting point for developing processes on a larger scale.
