Lab-scale Studies

Laboratory-wide studies have been conducted on the discoloration of single synthetic dye solutions and dye wastewater simulated by fungal biosorption / biodegradation, it is necessary to provide relative performance data on dye effluents Discoloration of industrial effluents resulting from dyeing The industry is illustrated in Figure 3. At pH 7.0 and 9.0, discoloration by Myrothecium sp. IMER1 at effluent concentrations of 30 % (v / v) was 73 and 70%, respectively, while in the case of white rot fungi, tests were less than 25% discoloration was observed.The result showed that Myrothecium sp. IMER1 had a higher color removal efficiency than these white rot fungi tested under neutral and alkaline conditions. On the one hand, when the UV-VIS spectra of the culture containing effluents of fluid dye at defined intervals in is were scanned from 350 to 800 nm, a marked decrease in maximum absorbance at 510 nm was observed at 6 days of incubation, which was linked to the decomposition of the chromophoric group in the effluent nt dyes (Figures 3b and 3c). On the other hand, the mycelium became deeply colored at the start of the discoloration, then became weak, finally almost disappeared (Figure 3d). Spectral analyzes of culture supernatants and color changes in fungal cells suggest that the dyes in the effluent have been removed by Myrotheciumsp. IMER1 mainly due to an enzymatic reaction.
