Screening and Identifying a Cadmium-resistant Fungus and Characterizing its Cadmium Adsorption

Research Progress of Soil Microorganisms in Response to Heavy Metals in Rice

“…Among them, Penicillium CN35 not only has a high concentration tolerance to both Pb and Zn up to 80 mmol/L but also has no disease and growth inhibition to rice seedlings. 17 Aspergillus aculeatus, isolated from the rhizosphere of rice, had the ability to produce IAA, siderophores, ACC deaminase, and phosphate solubilization. This strain can enhance the binding ability of the rice root cell wall to Cd, reducing the content of inorganic Cd in the root and inhibiting the expression of OsNRAMP5 and OsNRAMP1 to reduce the Cd content in rice grains by 40.5% and the Cd content in roots by 36.5%.…”

“…30 Studies have shown that Penicillium CN35 can adsorb 83.56% Cd under 45 mmol/L Cd concentration. 17 Rice roots were inoculated with Enterobacteriaceae S8 under the condition of 3000 μg/mL Cd, the morphology of the strain was not distorted by scanning electron microscope, and the removal rate of Cd was 95%. 23 Arbuscular mycorrhiza inoculated into rice could increase the expression of groups related to the adsorption and fixation of Cd 2+ in cell wall of root, thereby resist the entry of Cd 2+ into rice.…”

Characterization of cadmium-tolerant endophytic fungi isolated from soybean (Glycine max) and barley (Hordeum vulgare)

“…After the first screening, 5 strains with the highest levels of Cd tolerance were selected for the next stage of the study: Beauveria bassiana Т7, Beauveria bassiana Т15, Rhodotorula mucilaginosa МК1, Rhodotorula mucilaginosa RH2, and Metsсhnicоwiа pulcherrima MP2. These strains have MICs from 290 to 2400 μg/ml, that similarly or higher than MICs for soil and endophytic fungal strains in other studies ( Fazli et al., 2015 ; Châu, 2013 ; Deng et al., 2017 ; Chakraborty et al., 2014 ; An et al., 2015 ; Xu et al., 2015 ; Li et al., 2016 ; Rehman et al., 2010 ; Shadmani et al., 2021 ).…”

“…A large number of studies are dedicated to the ability of using fungi to remove Cd from various polluted sites. The ability of active Cd removal is described for many typical representatives of soil and endophytic fungal microflora – Aspergillus ( Chakraborty et al., 2014 ; Fazli et al., 2015 : Manguilimotan and Bitacura, 2018 ; Alothman et al., 2019 ) , Alternaria , Microdochium , Bipolaris , Alternaria , Pleosporales Fusarium Paecilomyces Clonostachys , Epicoccum ( Shadmani et al., 2020 , 2021 ) , Microsporum, Terichoderma ( Fazli et al., 2015 ), Fomitopsis, Trichoderma, Rhizopus ( Oladipo et al., 2018 ), Beauveria ( Fomina et al., 2005 ; Kameo et al., 2000 ), Paraphaeos, Pyrenochaeta, Rhizopycnis ( An et al., 2015 ), Penicillium ( Deng et al., 2017 ; Li et al., 2016 ; Manguilimotan and Bitacura, 2018 ; Alothman et al., 2019 ), Candida ( Châu, 2013 ; Rehman et al., 2010 ), Cryptococcus ( Châu, 2013 ), Exophiala ( Zhao et al., 2015 ), Rhodotorula ( Li and Yuan, 2008 ), Zygosaccharomyces, Saccharomyces ( Li et al., 2014 ), Aureobasidium ( Mowll and Gadd, 1984 ).…”

Removal of Lead and Cadmium Ions from Water Using Cladophora Biomass

“…In the biosorption method, pretreated natural substances such as seaweed or algae are used as sorbents of pollutants and become a promising alternative to the traditional physicochemical methods used for water treatment [7][8][9][10][11][12]. The Red Sea area features an important biodiversity hotspot for marine life organisms that is still being explored [13].…”
