“…The maximum adsorption capacities on the adsorption of CR by cattail root at 20, 30 and 40 • C were 38.79, 34.59 and 30.61 mg g −1 , respectively, indicating that increasing temperature induced a lower maximum adsorption capacity. As listed in Table 4, in comparison with other materials, the maximum adsorption capacities of CR on cattail root was lower than that of activated carbon, but higher than that of wheat bran, waste orange peel and sodium bentonite [35,[39][40][41]. R L , a dimensionless constant, was usually used to determine whether an adsorption is favorable, which was calculated by Eq.…”

“…Several studies have shown the biosorption potential of different lignocellulosic materials [18, 19]. Because dye-adsorbed lignocellulosics create another source of pollution, adsorption of dyes onto lignocellulosic materials does not completely solve this problem.…”

BackgroundLaccases are multicopper oxidases with high potential for environmental and industrial applications. Low-cost laccase production could be achieved by solid state fermentation on agro-industrial by-products.MethodsA number of agro-industrial solid wastes were tested as support-substrate for laccase production by Coriolopsis gallica under solid-state fermentation (SSF) conditions. Response surface methodology (RSM) was used to optimize the medium composition for laccase production. Initial screening by Plackett-Burman design was performed to select the major variables out of 20 tow medium components fellowing this Central composite design (CCD) was employed to optimize the level of the selected variables.ResultsSawdust waste was shown to be the best support-substrate for laccase production by the C. gallica. Peptone as source of organic nitrogen, Cd2+ as laccase inducer and liquid/solid (L/S) ratio were found to have significant effects on laccase production. Operating at optimum concentrations of the most significant variables (peptone, 4.5 g L−1, L/S ratio, 5.0 and Cd+2 1.0 mM) extracellular laccase activity was enhanced from 1480 U L−1 (60.5 U g−1), to 4880 U L−1 (200 U g−1) which meant a 3.2-fold increase in laccase activity. On the other hand, sawdust waste was studied as a low cost adsorbent to remove the azo dyes Reactive Black 5 (RB5) and Acid Orange 51 (AO51). Decolorization percentages around 67 and 75 % were obtained in 24 h for RB5 and AO51, respectively.ConclusionWhen used as a support substrate, sawdust yielded the highest laccase production which was increased 3.2 times using RMS optimization.

A B S T R A C TInvestigations have been carried out to study the use of Bengal gram fruit shell (SP) as a low-cost, eco-friendly biosorbent for the removal of Congo red (CR) from aqueous solution. Fourier transform infrared spectrometer and SEM were used to carry out characteristic studies on the material prepared. The effects of solution pH, biosorbent dosage, dye concentration, temperature, and contact time on the biosorption of CR onto the SP were investigated. The experimental results showed that maximum pH for efficient CR biosorption was about 8.0. Langmuir and Freundlich isotherm models were used for analyzing the equilibrium data. The maximum monolayer biosorption capacity was found as 22.22 mg g −1 at 35˚C. Kinetic studies indicated that the pseudo-second-order model fitted the experimental data well. Thermodynamic parameters demonstrated that the biosorption process was spontaneous and endothermic. The results revealed that the SP could be used as a low-cost and eco-friendly alternative biosorbent for the CR removal from wastewater.
