15/10/2011, · The FC-FISH analyses of bacteria and two main yeast species showed that the DO shift resulted in a sharp increase of T. asahii, by a factor of 48-60, which caused filamentous yeast bulking. Subsequently, the restoration of DO levels to, <0.5 mg L⁻¹ effectively restored the sludge settlement and yeast community,, as well as unacceptable COD removals.
