Biosorption Potential of Phanerochaete chrysosporium for Arsenic, Cadmium, and Chromium Removal from Aqueous Solutions

Abstract

Efficient degradation of hazardous contaminants from contaminated water is the major challenge for researchers, wherein heavy metals are the prominent contaminants. Consequently, the assessment of multimetal removal is necessary using efficient biosorbant. In this work, the capability of Phanerochaete chrysosporium is evaluated for the individual and simultaneous removal of heavy metals. Individual and simultaneous removal of As, Cd, and Cr is optimized using response surface methodology based on the central composite design by changing the variables, i.e., pH, fungal biomass, and metal concentration. Optimization of the individual metal removal study reveals that fungus effectively absorbs As (29.95 mg L −1 ), Cd (18.1 mg L −1 ), and Cr (26.34 mg L −1 ) at 6.1, 5.64, and 4.15 of pH, respectively. Similarly, As (14.18 mg L −1 ), Cd (4.53 mg L −1 ), and Cr (9.28 mg L −1 ) are absorbed by fungal hyphae simultaneously within 1 h. Changes in the morphology of fungal hyphae are detected in metal absorbed samples as compared to the control hyphae. Interaction of metal‐absorbed fungal hyphae is analyzed using FTIR spectroscopy, revealing that the proteins, carbohydrates, and fatty acids present in the fungal cell are interacted with metals. The model white rot fungi used in the present study can be applied efficiently for the multimetal removal in effluent treatment plants.

Response in Cadmium Tolerance of Penicillium cyclopium Westling Subsequent to Exposure to Gamma Irradiation

“…Significant changes in the same functional groups in the gamma exposed fungi additionally treated with metals, confirms potential of gamma irradiation in modulating heavy metal tolerance in fungi involving important functional groups. Similar type of results have been reported earlier also (Manal et al, 2020;Rudakiya et al, 2018).…”

White rot fungus mediated removal of mercury from wastewater

“…This extracellular ligninolytic systems primarily involves laccase, lignin peroxidase, manganese peroxidase and versatile peroxidases that provides a powerful defense against xenobiotic compounds (Zhuo & Fan, 2021). Furthermore, WRF releases carboxylic, and thiol group, organic acids, and some other polymeric elements extracellularly that may decrease the bioavailability and toxicity of heavy metals ions (Rudakiya et al, 2018). These WRF have the capability of intracellular accumulation and binding of heavy metals on outer cell membrane (Javaid et al, 2011).…”

“…Heavy metals present in industrial wastewater along with several chemicals and metallurgical elements may cause critical adverse environmental and health effects (Rudakiya et al, 2018). Mercury (Hg) contamination in water resources primarily comes from natural sources, including geothermal springs, volcanoes, and geologic deposits along with human-related sources which include waste incineration, coal combustion, mining and industrial effluents.…”

Comparative Copper Resistance Strategies of Rhodonia placenta and Phanerochaete chrysosporium in a Copper/Azole-Treated Wood Microcosm

“…One of the probable mechanisms of resistance could be the biosorption ability of this species, which was highlighted by SEM coupled to EDS microanalyses. The high capacity for biosorption was already demonstrated for P. chrysosporium , with most studies describing the biosorption of metals, and water contaminants in particular, from aqueous systems [ 22 , 52 , 53 , 54 ]. There is limited research on the mechanisms and performance for Cu biosorption in fungi.…”
