Although in this step the dyes undergo a process of dilution, the environmental impact is not eliminated due to the fact that triphenylmethane dyes increase the chemical oxygen demand (COD), biological oxygen demand (BOD), solids content, water color, and can cause acute toxicity at different trophic levels (Przystas et al.
These chemical characteristics determine that triphenylmethane dyes are more resistant to biological degradation than other families of dyes and explains how biodegradation byproducts of these dyes can form intermediaries with more toxicity than the initial compound.
For the biological removal of triphenylmethane dyes, there have been several successful studies using aerobic and anaerobic bacteria.
On the other hand, mycelia morphology of Pleurotus ostreatus (thin hyaline hyphae, long and pellets) and spore production are additional functional aspects that favor the removal of triphenylmethane dyes.
