“…Advanced studies on heavy metal remediation have been a priority in the development of environmental strategies. Among them, microbial approaches and heavy metal-tolerant microbes have proven to be the most promising options (Rahman 2020). The complex mechanisms of microbial remediation, including chemical-microbial interactions, were recently elucidated (Yin et al 2019;Islam et al 2021b), while heavy metal-tolerant microbes were considered potential candidates for advanced genetic development for sustainable field applications.…”

“…During recent decades, numerous strains of bacterial and fungal species which promote plant growth and absorb Cd have been isolated and used for remediation by direct inoculation into soils or with carriers such as biochar (Rahman, 2020). The inoculation of Serratia marscens PRE01 decreased Cd phytotoxicity by adsorption and increase the growth of Pteris vittate (Wang et al, 2018).…”

There is growing global interest in the bioremediation of cadmium (Cd) using combinations of biochar and microorganisms. However, the interactions among biochar, introduced and indigenous microorganisms remain unclear. Accordingly, a 90 day microcosm experiment was conducted to investigate this by adding Bacillus sp. K1 strain inoculated rice straw biochar (SBB) and magnetic straw biochar (MBB) into a Cd contaminated paddy soil from Hunan, China. All treatments were incubated aerobically (60% water holding capacity) or anaerobically for 90 d. During both soil incubations, Bacillus sp. K1 successfully colonized in soil with composites applications. Soil pH was significantly increased from acid to neutral, and available Cd decreased with the addition of both composites. The better remediation efficiency of MBB than SBB under anerobic conditions was attributed to the transformation of acetic acid-extractable Cd into the residual fraction, caused by Cd 2+ bonding with crystal Fe 3 O 4 . The application of the two kinds of composites caused similar changes to both microbial communities. There was a slight decrease in indigenous microbial alpha diversity with the MBB aerobic application, while the total population number of bacteria was increased by 700%. Both the redundancy analysis and Mantel analyses indicated that pH and microbial biomass C contributed to the colonization of Bacillus sp. K1 with SBB under aerobic conditions, and with MBB under anerobic conditions, respectively. The research provides a new insight into interactive effects and investigates immobilization mechanisms involved of bacterial/biochar composites in anaerobic and aerobic soils.

(Rahman, 2020) stated in his study that pollution with heavy metals produced negative effects such as mutagenic, teratogenic and carcinogenic effects in humans and wildlife.…”

This research is concerned with organisms isolated from soils contaminated with heavy metals in industrial and residential areas in the city of Mosul, the center of Nineveh Governorate, and the diagnosis of these organisms using molecular biology technique. Samples were collected from four locations in the city between the industrial area and residential neighborhoods. Soil samples were analyzed and dilutions were prepared, then the dilutions were grown on potato extract and dextrose (PDA) medium for the development of fungi and Nutrient agar for bacterial development. The dilutions were planted by casting method by three replications, then the process of purifying the fungal and bacterial colonies was carried out using the traditional methods. For the purpose of diagnosing these pure colonies using PCR technique, colonies of fungi were grown on the medium of PDA, and bacteria were grown on the medium of nutritious broth. As a result, nine fungal species were diagnosed, two of them are new undiagnosed genera that have been registered in the gene bank, four of them contain genetic mutations, and three of them are known and previously diagnosed fungi. As for bacteria, two new strains were isolated and registered in the gene bank among the four types that were diagnosed. And some of these genera exhibited severe resistance to antibiotics, while others showed moderate resistance, in contrast to the control, which was very sensitive to antibiotics.
