[PMID: 37631549 PMCID: PMC10460086 DOI: 10.3390/polym15163492] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 08/10/2023] [Accepted: 08/17/2023] [Indexed: 08/27/2023] Open
Abstract
Oxidase and peroxidase enzymes have attracted attention in various biotechnological industries due to their ease of synthesis, wide range of applications, and operation under mild conditions. Their applicability, however, is limited by their poor stability in harsher conditions and their non-reusability. As a result, several approaches such as enzyme engineering, medium engineering, and enzyme immobilization have been used to improve the enzyme properties. Several materials have been used as supports for these enzymes to increase their stability and reusability. This review focusses on the immobilization of oxidase and peroxidase enzymes on metal and metal oxide nanoparticle-polymer composite supports and the different methods used to achieve the immobilization. The application of the enzyme-metal/metal oxide-polymer biocatalysts in biosensing of hydrogen peroxide, glucose, pesticides, and herbicides as well as blood components such as cholesterol, urea, dopamine, and xanthine have been extensively reviewed. The application of the biocatalysts in wastewater treatment through degradation of dyes, pesticides, and other organic compounds has also been discussed.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 775:145798. [PMID: 33611184 DOI: 10.1016/j.scitotenv.2021.145798] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 02/04/2021] [Accepted: 02/07/2021] [Indexed: 06/12/2023]
Abstract
A strategy involving biochar (BC) hybrid modification was developed to promote the bioremediation effect of degrading bacteria immobilized in layer-by-layer assembly (LBL) microcapsules for the treatment of phenanthrene (PHE) polluted soil. A taxonomic and functional metagenomic approach was used to investigate changes in the microbial community structures and functional gene compositions in the PHE-polluted soil during the bioremediation process. Biofortification with an initial PHE concentration of 100 mg kg-1 dry soil in soils using the BC (3%) hybrid LBL bio-microcapsule (BC-LBL, 2.0 g kg-1 dry soil, 107 colony forming unite cell g-1 dry soil) was faster; further, a higher PHE degradation efficiency (80.5% after 25 d) was achieved when compared with that by the LBL agent (66.2% after 25 d) used. Sphingomonas, Streptomyces, Gemmatirosa, Ramlibacter, Flavisolibacter, Phycicoccus, Micromonospora, Acidobacter, Mycobacterium and Gemmatimonas were more abundant in BC-LBL treatment than those in LBL one. Functional gene annotation results showed that more gene number with BC-LBL treatment than those with LBL one. More abundant functions in the former were primarily related to the growth, reproduction, metabolism, and transportation of bacteria. BC hybridization promoting PHE degradation by microencapsulated bacteria may be due to the strong adsorption property of BC, which results in the enrichment of the nutrients that needed for bacterial growth and reproduction, as well as enhancing the mass transfer performance of PHE to BC-LBL; Meanwhile, BC could also stimulate and improve the metabolism and membrane transportation of the degrading bacteria, and finally improving the degradation function.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2019; 26:6388-6398.

Abstract
This study investigated the removal and translocation mechanism of cadmium (Cd) by Oudemansiella radicata (O. radicata) in mushroom-soil rhizosphere and the fruiting body of mushroom. For this, the biomass, physiochemical parameters, and Cd distribution of O. radicata were examined in the soil spiked with 0, 10, 20, and 30 mg kg-1 Cd. The soil microecology and the Cd fractionation in the soil rhizosphere were also measured. Results showed that, O. radicata possesses high capability to tolerate Cd, although its surface phenotypic structure was influenced by high concentrations of Cd. The observed concentrations of Cd in O. radicata were in the following order: root (the part of stipe in soil) > pileus > stipe. The presence of Cd led to an increase in the production of antioxidant enzymes and glutathione (GSH). These results suggested that antioxidant enzymes and GSH assisted detoxification and accumulation of Cd within the mushroom. Meanwhile, in the soil rhizosphere, the concentrations of oxalic, citric, and malic acids were enhanced with the treatment of Cd, indicating that the production of these acids was closely related to the presence of Cd in soils. Additionally, the proportion of acid-soluble Cd was increased and the soil microecology (microbial counts, urease, and acid phosphatase activities) also enhanced with the inoculation of O. radicata. Overall, this study demonstrated that O. radicata is a promising candidate for the remediation of Cd-contaminated soil.
