Abstract:
This work aimed to study the fate and effect of β-hexachlorocyclohexane (β-HCH) during several steps of PHA production and purification, by using an artificially contaminated cheese whey (CW) as the feedstock. Most of β-HCH (around 90%) was adsorbed on CW solids and it was removed after the acidogenic fermentation step, when residual CW solids are separated along with anaerobic biomass from the liquid-phase. Purification steps also contributed strongly to the removal of residual β-HCH; overall, the PHA production process removed about 99.9% of initial β-HCH content. Moreover, it has been shown that β-HCH has neither detrimental effect on acidogenic fermentation nor on PHA accumulation, that were performed by using unacclimated mixed microbial cultures.
