文摘
- •
Ethylene glycol (EG) and propylene glycol (PG) were utilized by C. protothecoides.
- •
EG degradation induced drastic reduction of pH, whereas PG did not induce pH change.
- •
Suitable pH condition was in the range of 5.5 to 8.5 for EG assimilation.
- •
High biomass yield (Yx/s = 0.52 g g− 1) was observed when PG was fed.
- •
Algal assimilation of EG and PG was investigated quantitatively for the first time.
