Description
Cheeranan Sriphuttha and co-authors brew oil and pigment together from biodiesel waste using a red yeast, in this 2023 paper. The yeast stores both fat and carotenoid color as it grows. Fed crude glycerol, the leftovers of biodiesel making, it performed best at a set feed strength found by systematic tuning. The team scaled the run to a five-hundred-liter fermenter under three feeding styles.
Fed-batch feeding won, filling over a third of the cell mass with lipid and reaching high pigment levels. A chemical-free extraction using pressure machines was tuned as well. The pigment proved to be mostly beta-carotene under three kinds of analysis. The authors frame the setup as a way to raise the value of a cheap waste stream.
