Abstract: DN322p, an offspring of DN322, has the capacity to adsorb and decolorize triphenylmethane dyes in wastewater simultaneously. As a common triphenylmethane dye, crystal violet (CV) was chosen to test the decolorization characteristics of DN322p. Within 0.5 h, the strain DN322p adsorbed a large amount of CV, producing a deep-colored cell pellet and colorless supernatant. The colors of the cell pellet and supernatant lightened over time. The supernatant and dichloromethane extract of the cell pellet both showed conspicuous CV and leuco CV (LCV) characteristic absorbance peaks at 590 nm and 260 nm, respectively, in the UV-vis spectral analysis. This finding indicated that the DN322p cells can adsorb the two dyes. A 99% (w/w) decolorization rate was achieved within 2.5 h with shaking at 30°C for 50 mg CV·L . High Performance Liquid Chromatography (HPLC) analysis of the dichloromethane extract of the supernatant and cell pellet confirmed that CV was mainly converted into its leuco form. Dead cells had a similar adsorption capacity with living cells. About 90% of CV in the dye solution (50 mg·L ) was removed by autoclaved cells with an optical delnsity at 600 nm (OD ) above 1.0.

Abstract: High quality and low cost carbon can be prepared from ( ) and Buckwheat straw. The biosorbent was used for Cr(VI) removal. The effect of experimental parameters, such as pH, sorbent dosage and temperature were examined and the optimal experimental condition was determined. Solution pH is found influencing the adsorption. Cr(VI) removal efficiency is found to be maximum (98%) at pH= 1. Langmuir and Freundlich adsorption isotherms were applicable to the adsorption process and their constants were evaluated. The adsorption data obtained agreed well with the Langmuir sorption isotherm model. The maximum adsorption capacities for Cr(VI) ranged from 46.23 to 55.19 mg·g for temperature between 298 K and 308 K under the condition of pH= 1.0. Thermodynamic parameters such as free energy change ( ), enthalpy ( ) and entropy ( ) indicate a spontaneous, endothermic and increased randomness nature of Cr(VI) adsorption. Studies found that the raw and buckwheat straw mixed materials with simple treatment had a high efficiency for the removal of Cr(VI) and would be a promising adsorbent.
