The removal of enoxacin (ENO), a broad-spectrum fluoroquinolone antibiotic, was firstly examined in a sulfate-reducing up-flow sludge bed (SRUSB) bioreactor over a long-term operation (366 days). Over 94% of the ENO was removed in the SRUSB bioreactor vi...

A new yeast wild-type Yarrowia lipolytica isolate presented efficient growth on glycerol. During flask cultures, nitrogen limitation led to the secretion of sugar-alcohols as the major metabolites of the process (mannitol, arabitol and erythritol), where...
