Analysis ABT-378 Variance (ANOVA) was carried out, followed by Tukey’s multiple comparison tests to reveal statistical significance of differences among time-course points and treatment means. Standard errors of mean values were estimated and multiple Pearson linear correlation coefficients r (p < 0.05 or p < 0.01) were calculated to assess relationships between variables. For all experimental setups and time-course sampling points, four replicates were used.
3. Results and discussion
3.1. Comparative evaluation of wood-rot fungal strains
T. versicolor CCBAS 614, and P. ostreatus strains LGAM 015 and LGAM 850 decreased COD by 58%, 47% and 43%, respectively ( Fig. 2). These are among the highest COD reductions reported for white-rot fungi used for OMW biodegradation ( Mebirouk et al., 2007). On the other hand, treatment of the effluent by certain strains resulted in an increase in COD compared to the control, which was as high as 70% for F. punctata CCBAS 662, G. resinaceum CCBAS-NA and T. panuoides LGAM 899 ( Fig. 2). No correlation among soluble COD and other pollution parameters and/or enzymes activities was found for those fungal strains which increased the COD values of the OMW medium, indicating possible organic matter release due to biomass decomposition.
