In these studies, the wastewater
treated by PSB had chemical oxygen demand (COD) values ranging
from 500 to 9800mg l1, and the effectiveness of the COD reduction
was satisfying. Apart from the ability to degrade pollutants under a
high COD load, PSB are nutrition-rich and contain high-value substances,
such as coenzyme Q10, 5-aminolevulinic acid and polyhydroxyalkanoate
