“…In conclusion, if acclimation to high concentrations of toxic phenolic products was described for activated sludge (Hickman and Novak 1984;Lund and Rodriguez 1984;Kwan-Hyung and Silverstein 2004), this aspect was however apparently ignored for fungi and yeasts that otherwise could be potentially useful for treating highly polluted effluents.…”

Olive oil mill wastewaters (OOMW) cause a recurrent environmental pollution problem. The large concentration of phenolic compounds in the organic fraction of OOMW is principally responsible for the phytotoxicity and microbial growth inhibitory effects of the effluent. Candida boidinii, Geotrichum candidum, a Penicillium sp. and Aspergillus niger HA37 were isolated from OOMW. When cultivated directly on an undiluted OOMW-based medium containing 82 g l -1 COD, these strains removed only 4-8% of chemical oxygen demand (COD) and phenolics. In contrast, reduction values attaining respectively 40-73% for phenolics and 45-78% for COD removal in the undiluted OOMW-based medium were obtained when using the strains gradually acclimated to high concentration of OOMW by successive stepwise transfer from media containing COD of 20.5 up to 82 g l -1 . Possibly, a sufficient production level of degradation and/or detoxification enzymes has to be attained to overcome the toxic effects of the phenolic fraction of concentrated OOMW. The present investigation calls attention to the necessity of acclimation for certain fungal and yeasts strains potentially useful for treating highly polluted effluents.

“…However, little attention has been paid to the acclimation process. Generally, acclimation denotes the adjustments made by microorganisms in response to changes in the environment commonly applied to activated sludge [20]. The adaptive mechanism involving acclimation process include mutation, enzyme formation, modification of cell structure, and composition changes of the population due to multiplication, death, or shifts in predominance [20].…”

“…Fischer (1979, 1981), however, reported that it was not degraded unless an acclimatised inoculum (Sturm) was employed. Similarly, Lund and Rodriguez (1984) did not find 3-CB to be biodegraded unless the inoculum had previously been pre-acclimatised (30d). They also found a sludge acclimatised to 3-methylbenzoic acid for 20d was not only able to degrade 3-CB but did so at a higher rate than sludges acclimatised to 3-CB.…”
