摘要：

A comparative study was performed onTrichoderma harzianumand a combination ofCandida boidinii/Bacillus pumilusto reduce the polluting effect of TOPW (Table Olive Processing Water) from the Spanish style. A 2(k)fractional design was used to study the effect of pH (6-11 for the fungus and 6-9 forCandida/Bacillus), temperature (10-35 degrees C) and duration (7-14 days forCandida/Bacillusand 14-21 days forT. harzianum), and the effect on phenol reduction, COD and color was evaluated. The experiments were also performed on diluted TOPW (dilution ratio 1:1). Generally,Trichodermaremoved higher amounts of phenols and reduced COD more than the combinationCandida/Bacillus, thus confirming the higher efficiency of filamentous fungi reported in the literature. The dilution of TOPW had an effect only on COD reduction; however, the effect was mild, at least forT. harzianum(4%), while yield increase was 9% forBacillus/Candida. pH acted in a different way on phenol removal and COD reduction; an increase of pH caused a reduction of efficiency for COD, while the effect was positive for phenols.
