Enzymatic and non-enzymatic removal of organic micropollutants with spent mushroom substrate of Agaricus bisporus

Article

Abstract:

Water bodies are increasingly contaminated with a diversity of organic micropollutants (OMPs). This impacts the quality of ecosystems due to their recalcitrant nature. In this study, we assessed the removal of OMPs by spent mushroom substrate (SMS) of the white button mushroom (Agaricus bisporus) and by its aqueous tea extract. Removal of acesulfame K, antipyrine, bentazon, caffeine, carbamazepine, chloridazon, clofibric acid, and N, N-diethyl-meta-toluamide (DEET) by SMS and its tea was between 10 and 90% and 0–26%, respectively, in a 7-day period. Sorption to SMS particles was between 0 and 29%, which can thus not explain the removal difference between SMS and its tea, the latter lacking these particles. Carbamazepine was removed most efficiently by both SMS and its tea. Removal of OMPs (except caffeine) by SMS tea was not affected by heat treatment. By contrast, heat-treatment of SMS reduced OMP removal to < 10% except for carbamazepine with a removal of 90%. These results indicate that OMP removal by SMS and its tea is mediated by both enzymatic and non-enzymatic activities. The presence of copper, manganese, and iron (0.03, 0.88, and 0.33 µg L-1, respectively) as well as H2O2 (1.5 µM) in SMS tea indicated that the Fenton reaction represents (part of) the non-enzymatic activity. Indeed, the in vitro reconstituted Fenton reaction removed OMPs > 50% better than the teas. From these data it is concluded that spent mushroom substrate of the white button mushroom, which is widely available as a waste-stream, can be used to purify water from OMPs.

Participation of Strong H-Bonding to Acidic Groups Contributes to the Intense Sorption of the Anionic Munition, Nitrotriazolone (NTO) to the Carbon, Filtrasorb 400

Article

作者: Seenthia, Nourin ; Abdelraheem, Wael ; Xu, Wenqing ; Meng, Lingjun ; Pignatello, Joseph J.

5-Nitro-1,2-dihydro-3H-1,2,4-triazin-3-one ("nitrotriazolone," NTO) is an insensitive munition compound used in modern weaponry. It poses a potential threat to soil and water quality at relevant sites due to its physical properties that cause high mobility in the environment. NTO is polar and predominantly monoanionic (NTO^-) at environmental pH (pK_a1 = 3.64 and pK_a2 = 11.06; determined by two independent methods in this study). Nevertheless, NTO^- sorbs strongly to the carbon, Filtrasorb 400 (Freundlich coefficient K_F = 1.26 × 10⁴ Lⁿ μmol^1-n kg^-1 at pH 9.5). We present evidence that sorption is contributed by the interaction of NTO^- with functional groups of similar acidity on the carbon to form exceptionally strong, negative charge-assisted hydrogen bonds, (-)CAHB, written (-N^-···H⁺···^-O-[Formula: see text]), where -N^- is the deprotonated N of NTO, and ^-O-[Formula: see text] represents a deprotonated surface group. Behaviors consistent with (-)CAHB include (1) a "hump" in the pH-sorption profile centered around pH 4, where maximal complexation is expected to occur; (2) an apparent ∼2.4-unit upward shift in pK_a1 due to the enhanced H-bond strength; (3) the consumption of a proton from water to form the complex; and (4) sorption suppression by competing (-)CAHB-capable solutes. Anion exchange played a minor role. The findings help advance our understanding of weak acids sorption by carbonaceous materials.

Characterization of oral drug absorption from jelly formulations: Effects of membrane permeability and intestinal fluid volume

Article

作者: Yamashita, Shinji ; Kataoka, Makoto ; Nakamura, Junko ; Hishikawa, Yoshihiro ; Kakino, Yukari ; Minami, Keiko

This study aims to clarify the process of oral drug absorption from jelly formulations. Agar and pectin-based jellies containing drugs with different membrane permeability (high: antipyrine [ANT], medium: metoprolol [MET], low: atenolol [ATE]) were prepared and tested for in vitro drug release and in vivo drug absorption in rats. All drugs showed similar release profiles in vitro from both jelly formulations, except for the faster release from pectin jelly at neutral pH. In contrast, in vivo absorption of ATE but not of ANT from jelly formulations was significantly lower than from solution. Absorption of ATE and MET was low from agar jelly after oral administration, whereas additional water intake significantly increased the absorption. The process of drug absorption was described by the compartmental model consisting of jelly, intestinal fluid, and blood compartments. Drugs in the jelly diffuse into the intestinal fluid and then permeate the intestinal membrane. By considering the rate-limiting process, membrane permeability-dependent drug absorption from agar jelly and the effects of water intake were identified. In conclusion, jelly formulations may potentially decrease and delay drug oral absorption, especially of poorly permeable drugs. Intestinal fluid volume is one of the important factors to control the drug absorption.
