“…SMS can be turned into compost and pit soil that can be sold to local supermarket, nurseries as well as vegetable gardens in the surroundings. Spent mushroom substrate were used as a source of immobilized mushroom mycelium, which is an efficient adsorbent of polluntants in mines and industry allowing 70-90% of pollutants removal [3]. According to Rinker [7], spent mushroom substrate has been used as an enzymes for bioremediation, animal feed, and energy feedstock.…”

“…In addition, Langmuir isotherms reported of monolayer adsorption through mushroom fruit bodies or spent mushroom substrate [3]. Mushroom product has been on an increase and in Iran, mushroom production industries has been on a rise and were reported to be generating more than 50,000 tons of spent mushroom substrate annually substrate [3]. The generation of spent mushroom substrate was generally two times higher than the mushroom harvested.…”

“…Among agricultural residues, those from edible mushroom waste production can be highlighted. Between 1997 and 2012, annual per capita consumption of edible mushrooms increased from about 1 to over 4 kg/y −1 worldwide [25]. Accordingly, in this way, the generation of their residues increased in the same direction, making stalks and substrates a possible issue, due to their disposal in the environment.…”

Agricultural waste products can be used as biosorbents for bioremediation once they are low-cost and high-efficient in pollutants removal. Thus, waste products from mushroom farming such as cutting and substrate of Lentinula edodes (popularly known as shiitake) and Agaricus bisporus (also known as champignon) were evaluated as biosorbents for metallic contaminants copper (Cu) and lead (Pb). Shiitake and champignon stalks, and shiitake substrate (medium in which shiitake was cultivated) were dried, grounded, characterized and experimented to remove Cu and Pb from contaminated water. The Sips model was used to establish the adsorption isotherms. Regarding Cu, champignon stalks have the best removal efficiency (43%), followed by substrate and stalks of shiitake (37 and 30%, respectively). Pb removals were similar among three residues (from 72 to 83%), with the champignon stalks standing out. The maximum adsorption capacities (qmax) for Cu in shiitake and champignon stalks were 22.7 and 31.4 mg/g−1, respectively. For Pb, qmax for shiitake and champignon stalks, and shiitake substrate were 130.0, 87.0 and 84.0 mg/g−1, respectively. The surface morphology of the champignon stalks revealed an organized and continuous structure. After an interaction with metals, the stalk of champignon accumulated the metal ions into interstices. Mushroom residues showed a relevant adsorption efficiency, especially for Pb. Mushroom farming waste are a very low-cost and promising alternative for removing toxic heavy metals from aquatic environment.

“…Environmental biotransformation is an excellent method that can provide solutions with the lowest input and has received worldwide acceptance to treat biphenyl and polyhalogenated biphenyls (Dannan et al 1982). Previous structural, molecular docking and biochemical studies reported that dehydrogenase BphB can efficiently degrade biphenyl and polyhalogenated biphenyls (Vezina et al 2007;Zhuang et al 2016;Jain et al 2018;Kulshreshtha 2018).…”

Effect of F, Cl, Br and I substitution on the BphB enzyme for the degradation of halogenated biphenyls, revealed by quantum and molecular mechanics

et al. 2019

Halogenated biphenyls are worldwide persistent pollutants of great environmental concern. In particular, polychlorinated biphenyls and polybrominated biphenyls have been globally used for industrial purposes until they were found highly toxic, mutagenic and carcinogenic to humans. Therefore, ecological strategies to remove halogenated biphenyls, such as enzyme-catalyzed degradation, are needed. Here, we studied the effect of substitution of F, Cl, Br or I at the 4,4′-positions of 2,3-dihydro-2,3-dihydroxybiphenyl-2,3-dehydrogenase (BphB) on the degradation of halogenated biphenyls by quantum and molecular mechanics. Results show that Boltzmann-weighted average degradation barriers of substituted BphB are all lower than the unsubstituted biphenyl, except for chlorinated biphenyl. The roles of residues nearby the active site, e.g., iso-leucine89, asparagine115, serine142, asparagine143, proline184, methionine187 and threonine189, were also investigated.
