“…These differences may be attributed to the different adaptation mechanisms of bacteria and archaea, which are beneficial to their survival and development of their respective taxa. On the other hand, members of the genera Salinarimonas and Paracoccus were previously isolated in oil-contaminated environments, indicating their role in hydrocarbon bioremediation (Zhang et al, 2020;Procópio, 2021). And bacteria belonging to Algoriphagus were also confirmed as an oil-degrading bacterium (Wang et al, 2014).…”

Brine from Dingyuan Salt Mine (Anhui, China), an athalassohaline hypersaline environment formed in the early tertiary Oligocene, is used to produce table salt for hundreds of millions of people. However, halophiles preserved in this niche during deposition are still unknown. Here, we employed cultivation and high-throughput sequencing strategies to uncover the microbial community and its shift after a long-term storage in the brine collected from Dingyuan Salt Mine. High-throughput sequencing showed (1) in the fresh brine (2021), Cyanobium_stocktickerPCC-6307 spp. (8.46%), Aeromonas spp. (6.91%) and Pseudomonas spp. (4.71%) are the dominant species in bacteria while Natronomonas spp. (18.89%), Halapricum spp. (13.73%), and Halomicrobium spp. (12.35%) in archaea; (2) after a 3-year-storage, Salinibacter spp. (30.01%) and Alcanivorax spp. (14.96%) surpassed Cyanobium_stocktickerPCC-6307 spp. (8.46%) becoming the dominant species in bacteria; Natronomonas spp. are still the dominant species, while Halorientalis spp. (14.80%) outnumbered Halapricum spp. becoming the dominant species in archaea; (3) Alcanivorax spp. and Halorientalis spp. two hydrocarbons degrading microorganisms were enriched in the brine containing hydrocarbons. Cultivation using hypersaline nutrient medium (20% NaCl) combined with high-throughput 16S rRNA gene sequencing showed that (1) the biomass significantly increased while the species diversity sharply declined after a 3-year-storage; (2) Halorubrum spp. scarcely detected from the environment total stocktickerDNA were flourishing after cultivation using AS-168 or NOM medium; (3) twelve possible new species were revealed based on almost full-length 16S rRNA gene sequence similarity search. This study generally uncovered the microbial community and the dominant halophiles in this inland athalassohaline salt mine, and provided a new insight on the shift pattern of dominant halophiles during a long-term storage, which illustrated the shaping of microorganisms in the unique environment, and the adaptation of microbe to the specific environment.

“…Corrosion is a detrimental problem for metal or alloy materials, and it has environmental implications for infrastructure and other assets that use these materials. , Moreover, corrosion causes extensive repair and replacement of assets, and the global cost of corrosion damage is more than $2.5 trillion . Within this process, a special form of corrosion termed microbiologically influenced corrosion (MIC) is a form in which microorganisms attach and produce biofilms on the surface − and directly or indirectly affect the corrosion reaction via the establishment of an electrochemical cell and stimulating anodic and cathodic reactions. , …”

The development of sustainable and nontoxic corrosion coatings in abiotic and biotic environments has recently attracted significant attention. Herein, we developed nanohybrid coatings containing polysulfone (PSU), cyclodextrin (CD), zeolite (10 μm size), and biogenic silver nanoparticles (AgNPs, 40 nm diameter) via direct one-step dual-spinneret electrospinning. In the fabricated nanohybrid coatings, zeolites were used as a nontoxic anticorrosive inhibitor, and biogenic AgNPs serve as antibacterial agents due to their environmentally friendly and low-cost characteristics. Scanning electron microscopy and transmission electron microscopy analyses indicated that the zeolite and AgNP-embedded nanofibers have homogeneous and bead-free morphologies. Moreover, the elemental distribution mapping of the fabricated platforms demonstrated a well-distributed mixture of PSU/zeolite and CD/ AgNPs in the nanofiber mats which were fabricated via such a dual-spinneret technique. The surface-enhanced Raman scattering activities of the fabricated nanofiber mats were also evaluated using methylene blue, rhodamine 6 G, crystal violet, and malachite green as probe molecules. Additionally, the antibacterial response of the fabricated nanohybrid coatings against four pathogenic bacteria (Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 23213, Pseudomonas aeruginosa ATCC 27853, and Klebsiella pneumoniae ATCC 700603) was investigated, which indicated the critical role of zeolite/AgNPs in suppressing the bacterial growth. Tafel measurements also showed that the PSU/zeolite/HPβCD/AgNPs hybrid coating reduced the corrosion current density of the Cu surface in the presence of P. aeruginosa ATCC 27853, which is a biofilm-producing bacteria, compared to the uncoated surface. The antimicrobial and corrosion inhibition ability of the fabricated nanohybrid coatings offers promising opportunities for the microbiologically influenced corrosion inhibition applications.

“…Moreover, several studies have demonstrated that many factors significantly affect steel corrosion in saline soils. These factors include soil moisture content [ 11 ], pH [ 12 , 13 , 14 ], ion concentration [ 15 , 16 , 17 ], and the presence of microorganisms [ 18 , 19 , 20 , 21 , 22 , 23 ]. Han et al found that corrosion rates increased as the pH of contaminated silty soil decreased [ 24 ].…”

In this paper, the electrochemical corrosion behavior of X70 steel in saline soil under capillary water was simulated by a Geo-experts one-dimensional soil column instrument. A volumetric water content sensor and conductivity test were used to study the migration mechanism of water and salt (sodium chloride) under the capillary water. The electrochemical corrosion behavior of the X70 steel in the corrosion system was analyzed by electrochemical testing as well as the macroscopic and microscopic corrosion morphology of the steel. The test results showed that the corrosion behavior of X70 steel was significantly influenced by the rise of capillary water. In particular, the wetting front during the capillary water rise meant that the X70 steel was located at the three-phase solid/liquid/gas interface at a certain location, which worsened its corrosion behavior. In addition, after the capillary water was stabilized, the salts were transported with the capillary water to the top of the soil column. This resulted in the highest salt content in the soil environment and the most severe corrosion of the X70 steel at this location.
