This study demonstrates that SFM fractionation is a feasible
refining concept leading to the production of an antioxidant-rich
stream, protein isolate and nutrient-complete fermentation media
for PHB production (Fig. 1 – Process II). Fermentation media were
produced from remaining fractions (Fig. 2) that resulted during
SFM fractionation. The recommended approach is based on the
principle of optimized resource utilization preventing the use of
commercial nutrient supplements. The techno-economic evaluation
of Processes I and II (Fig. 1) will be presented in a forthcoming
study.
