Özet
Previous works reported lacease production ability of batch cultures of white rot fungi in olive oil mill wastewater media (OOMW). Therefore, here, lacease production ability of repeated-batch cultures of Funalia trogii and Trametes versicolor pre-grown pellets in olive oil mill wastewater media (OOMW) was investigated and conditions for lacease production were optimized. The results indicated that high amounts of lacease could be obtained by using the best production conditions such as agitation, initial pellet amounts, initial pH, OOMW concentration and temperature. All these conditions were found to be important for lacease production. After optimization, the effect of various supplementary sources and inducer (glucose, malt extract, cheese whey and copper) on lacease production ability of these fungi and longevity of this production ability were examined in repeated-batch process. Presence of glucose, malt extract, cheese whey and copper positively affected the lacease production ability and longevity of the production. The fungal pellets also partially bioremediated the OOMW during lacease production and F. trogii pellets removed 33% COD from OOMW effluent whilst T. versicolor removed 28% in the first use. © by PSP.
