“…Bendras dviejų bakterijų naudojimas gali veiksmingai padėti atkurti tropinius dirvožemius, užterštus Cd ir Cr (Liu et al, 2024). Bacillus cereus BCS1 efektyviai suardė 84 % β-cipermetrino (β-CP) net ir veikiant įvairioms švino (10-1000 mg•L−1), taip pat chromo (10-1000 mg•L−1) arba kadmio (0,5-50 mg•L−1) koncentracijoms (Huang et al, 2024).…”

Žmonių veikla (pramonė, žemės ūkis, kasyba, sąvartynai) susijusi su dirvožemio tarša sunkiaisiais metalais. Ši tarša neigiamai veikia visus gyvus organizmus, įskaitant ir dirvožemio mikroorganizmus. Esant nedidelei sunkiųjų metalų koncentracijai dirvožemio mikroorganizmai gali pašalinti juos. Darbo tikslas: išanalizuoti sunkiųjų metalų sąveiką su dirvožemio mikroorganizmais remiantis pateiktais moksliniais straipsniais. Tiriamas dirvožemio užterštumas įvairiais sunkiaisiais metalais, bet daugiausiai analizuojami kadmis, varis, švinas. Moksliniuose straipsniuose daugiausiai atliekami fitoremediacijos tyrimai, skirti ištirti ryšiui tarp sunkiųjų metalų ir dirvožemio mikroorganizmų naudojant augalus. Taip pat tyrimai atliekami naudojant dirvožemį, užterštą vykdant antropogeninę veiklą. Literatūroje aprašomi su sunkiaisiais metalais užteršto dirvožemio tyrimai, kurie atskleidžia mikroorganizmų panaudojimo galimybes bei jų pokyčius laikui bėgant.

“…First, HMes in sediments can affect important functions of microorganisms, e.g., respiration (because of the inhibition of the electron transport chain), cell division, nitrification, denitrification, functions related to the carbon cycle, and genetic information processes [ 3 , 5 , 6 , 7 ]. Hence, the inhibition of microbial communities by HMes can affect the biogeochemical cycling of nutrients.…”

“…Third, HMe-tolerant bacteria can be cross-resistant toward organic pollutants; e.g., HMe-tolerant Bacillus cereus BCS1 degrades pyrethroid [ 5 ], and furthermore, HMe tolerance among bacterial species derived from hydrocarbon-contaminated sites has been detected [ 14 ]. Arsenic-resistant bacteria have been isolated from uranium ore [ 9 ].…”

“…SUK 1201 was reported by Dey and Paul (2016) [11]. Special attention can be paid to phytoremediation, which is based on plant-microbe interactions caused by rhizofiltration, phytostabilization, phytoextraction, phytostabilization, and phytovolatilization [5,12]. Furthermore, bacteria belonging to Actinobacteria, Firmicutes, and Proteobacteria help fish Pterygoplichthys pardalis overcome HMe stress in their intestines [13].…”

Heavy metal (HMe) pollution in regions with mining and metallurgy activities is known to be a serious environmental problem worldwide. Hydrological processes contribute to the dissemination of HMes (drainage, precipitation, flow rate). The aim of the present study is to investigate the microbial community structure in ten river sediments sampled in different regions of East Kazakhstan, which are contaminated with HMes. The overall degree of sediment contamination with HMes (Cr, Cu, Zn, Pb, and Cd) was assessed using the pollution index Zc, which ranged from 0.43 to 21.6, with the highest in Ridder City (Zc = 21.6) and Ust-Kamenogorsk City, 0.8 km below the dam of the hydroelectric power station (Zc = 19.6). The tested samples considerably differed in organic matter, total carbon, nitrogen, and phosphorus content, as well as in the abundance of HMe-related functional gene families and antibiotic resistance genes. Metagenomic analysis of benthic microorganisms showed the prevalence of Proteobacteria (88.84–97.61%) and Actinobacteria (1.21–5.98%) at the phylum level in all samples. At the class level, Actinobacteria (21.68–57.48%), Betaproteobacteria (19.38–41.17%), and Alphaproteobacteria (10.0–39.78%) were the most common among the classified reads. To the best of our knowledge, this is the first study on the metagenomic characteristics of benthic microbial communities exposed to chronic HMe pressure in different regions of East Kazakhstan.

“…Additionally, other species such as B. sterothemophilus, B. megaterium, B. pumilus, B. licheniformis, and B. jeotgalim have shown bioremediation capabilities [28][29][30][31], producing various secondary metabolites such as lipopeptides, polypeptides, macrolides, fatty acids, polyketides, and isocoumarins, which enable them to decontaminate soils polluted with toxic metals and organic pollutants [32]. Bacillus cereus, in particular, has been employed in various studies to break down toxic metals [33][34][35], hydrocarbons [36,37], free cyanide [38,39], pesticides [40,41], and polypropylene [42]. Given its broad applicability in bioremediation processes [43,44], unique biotechnological properties [20][21][22], involvement in the microbiota of contaminated soils, and tolerance for free cyanide, it is crucial to address the preservation of Bacillus cereus [45].…”

Lyophilization is a widely employed long-term preservation method in which the bacterial survival rate largely depends on the cryoprotectant used. Bacillus cereus strain PBC was selected for its ability to thrive in environments contaminated with arsenic, lead, and cadmium, tolerate 500 ppm of free cyanide, and the presence of genes such as ars, cad, ppa, dap, among others, associated with the bioremediation of toxic compounds and enterotoxins (nheA, nheB, nheC). Following lyophilization, the survival rates for Mannitol 2.5%, Mannitol 10%, and Glucose 1% were 98.02%, 97.12%, and 96.30%, respectively, with the rates being lower than 95% for other sugars. However, during storage, for the same sugars, the survival rates were 78.71%, 97.12%, and 99.97%, respectively. In the cake morphology, it was found that the lyophilized morphology showed no relationship with bacterial survival rate. The best cryoprotectant for the PBC strain was 1% glucose since it maintained constant and elevated bacterial growth rates during storage, ensuring that the unique characteristics of the bacterium were preserved over time. These findings hold significant implications for research as they report a new Bacillus cereus strain with the potential to be utilized in bioremediation processes.
