Growth occurred at 15-37 °C (optimum, 30 °C), at pH 7-9 (optimum, pH 7-8) and with 0-1% NaCl (optimum, 0.5%). The major isoprenoid quinone was ubiquinone-8 (Q-8). The predominant fatty acids were summed feature 3 (C_16:1 ω6c and/or C_16:1ω7c) and C_16:0. The polar lipids comprised phosphatidylethanolamine, diphosphatidylglycerol, five unidentified phospholipids and two unidentified aminophospholipids. The G + C content of the genomic DNA was 53.8%. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain FCG-7^T belonged to the genus Chitinibacter and was closely related to Chitinibacter bivalviorum 2T18^T (similarity 99.29%) and Chitinibacter fontanus STM-7^T (similarity 98.85%). The average nucleotide identity (ANI) values of FCG-7^T and the above two type strains were 81.4-83.1%, and the digital DNA-DNA hybridization (dDDH) values were 22.9-24.3%.

For instance, it increases the intensity of rainfall, leading to soil erosion and leaching of heavy metals, pesticides and other pollutants into the water bodies. Additionally, climate change intensifies both natural processes and anthropogenic activities resulting in the widespread release and dispersal of heavy metals (HMs) and other pollutants, posing great risk to environment and human health. Cr (VI) is the most hazardous metal contaminant in the ecosystem. In the environment, it often coexists with other heavy metal such as Fe (III), Zn (II), Pb (II), Hg (II), Cd (II) and Cu (II) which interferes with the Cr (VI) removal strategies and significantly influence the efficiency of bioremediating microbes. In this study, the Cr (VI) removal potential of the novel microbe Bacillus sp. SSAU-2 was explored in the presence of multi-heavy metal contaminations in various combinations. The tolerance against HM of the SSAU-2 was analyzed with minimum inhibition concentration (MIC) study and the mechanism was observed by analyzing the various types pf Siderophore production in the presence of HM. Revealed that the SSAU-2 exhibits multi-heavy metal tolerance, with the following MIC order Pb (II) > Fe (III) > Cu (II) > Cr (VI) > Zn (II) > Cd (II) > Hg (II). The presence of Zn (II), Fe (III) and Cu (II) acted as positive inducers, enhancing its growth and Cr (VI) removal efficiency. Although SSAU-2 demonstrates remarkable resistance to most heavy metals, it is highly susceptible to Hg (II) and Cd (II). However, Hg (II) proved to be the most toxic, reducing the Cr (VI) removal efficiency from 83 to 32% even at a concentration of 0.1 ppm concentration. The mechanism underlying its multi-heavy metal tolerance is linked to the production of siderophore, particularly catechol-type siderophore. Thus, this study highlights the potential of SSAU-2 as a robust microbe, capable of sustaining its Cr (VI) removal ability even in the presence of multiple heavy metals. Therefore, this microbe can tackle the adverse climate change phenomenon and environmental pollution altogether.</p>","PeriodicalId":11360,"journal":{"name":"Current Microbiology","volume":"82 7","pages":"293"},"PeriodicalIF":2.3,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144110293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, viral diseases pose a major challenge, causing yield losses of up to 80% and significant economic damage. More than 50 distinct viruses infect wheat, with key threats including wheat streak mosaic virus (WSMV), barley yellow dwarf viruses (BYDVs), high plains wheat mosaic virus (HPWMoV), soilborne wheat mosaic virus (SBWMV), and wheat yellow mosaic virus (WYMV). These viruses are primarily transmitted by vectors such as wheat curl mites (Aceria tosichella), aphids, and soilborne fungi like Polymyxa graminis. Diagnosing wheat viral infections is challenging due to overlapping symptoms with other plant stresses and the microscopic nature of viruses. Recent advancements in molecular and serological diagnostics, including Enzyme-Linked Immunosorbent Assay (ELISA), RT-Polymerase Chain Reaction (RT-PCR), CRISPR-based detection, and biosensors, have improved virus identification and monitoring. Since chemical treatments are ineffective, integrated management strategies such as breeding virus-resistant varieties, controlling vector populations, adjusting cultural practices, and utilizing RNA interference (RNAi) are essential for mitigating disease spread.

Shewanella azerbaijanica has the ability to reduce uranium. This study examined the impact of high-nitrate concentrations on uranium bioreduction in both native and recombinant bacterial strains. Bacterial performance was evaluated in terms of uranium bioreduction (measured via ICP-AES method), and survival in anaerobic conditions (measured via Neubauer chamber counting) in the presence of uranium and nitrate over various time intervals (24 h, 1 week, 4 weeks, 4 months, and 9 months). Although the recombinant strain showed a lower cell population than the wild-type strain, it achieved 20% higher uranium reduction after 24 h of incubation in uranium and nitrate-containing conditions. This suggests that the genetic modifications enhanced extracellular electron transfer (EET). The improved bioremediation efficiency may be attributed to the cloned mtrC gene, which promotes more effective electron transfer in Shewanella bacteria. Additionally, uranium removal may have been further enhancedby the inactivation of the napB gene using the SDM method. This high-performance trends was consistent across all time intervals.
