Given that most of the subsurface formations are biological active environments, the deep microbial biosphere plays an important role in governing the fate and sequestration efficiency of injected CO₂. While substantial researches have explored the initial states and microbial shifts following CO₂ injection, there remains a notable gap in studies that systematically examine the interactions between deep microbial biospheres and geologically injected CO₂. Such understanding is essential for elucidating mechanisms and extents of geochemical CO₂ evolution under the subsurface microbial mediation. This paper comprehensively examines recent findings about impacts of CO₂ injection on deep microbial biosphere, and discusses microbial responses that are pivotal in determining the fate of the injected CO₂. Initially, the review addresses the influence of elevated CO₂ on geological chemistry, including pH, ionic strength, redox state and free energy distribution. Subsequently, it delves into the adverse effects of CO₂ on microbial growth, cell integrity, endospore generation, metabolism and community dynamics. Lastly, the review emphasizes key microbial activities that potentially facilitate <em>in situ</em> CO₂ immobilization, including CO₂ mineralization, methanogenesis and conversion to other valued chemicals. The objective of this review is to elucidate how elevated CO₂ levels affect geological microbiology, and how microbial responses impact the fate and speciation of CO₂ in storage sites, and to provide insights for optimizing future CO₂ storage strategies in geological formations.</div></div>","PeriodicalId":13643,"journal":{"name":"International Biodeterioration & Biodegradation","volume":"197 ","pages":"Article 105958"},"PeriodicalIF":4.1,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study investigated the distribution and diversity of comammox across the major estuarine wetland systems along the coast of China by comparing different land types, including paddy fields (PF), aquaculture ponds (AP), and wetlands. The results showed that reclamation for PF and AP (1.94 × 10⁶ copies g⁻¹ soil) significantly reduced the gene abundance of comammox compared with wetlands (3.19 × 10⁶ copies g⁻¹ soil), with higher ammonia-oxidizing archaea (AOA) and bacteria (AOB) abundances and the rates of nitrification in PF than in AP. Phylogenetic analysis revealed different community structures in the two reclamation types. The distribution pattern of comammox genes in PF was similar to that in estuarine wetlands, with clade A1 and clade A2.1 being the dominant branches. Water content, iron, sulfide, and salinity were identified as the key factors affecting the distribution of comammox.

Also briefly summarizes different MP's exposure routes and their negative consequences on public health. Various conventional methods have been used to remove MPs but these are inefficient owing to several demerits. Microbial approach is regarded as a safer option for removing MPs due to its unique metabolic mechanism. More than 400 microorganisms have been discovered as capable of MPs degradation. Fungi have appeared as the most proficient degraders of plastics among the microbes because they release unique enzymes and can thrive on hazardous components with low resources. Numerous fungal species that can break down various plastic kinds have been found in recent studies; nevertheless, there are still many unanswered questions regarding the mechanisms underlying biodegradation. The molecular mechanisms behind MP degradation via various enzymes have received little attention. Also, white-rot fungi have received the least attention among the fungi examined for biodegradation despite having a unique extracellular enzymatic system. Thus, the current study summarizes the ability of fungi that degrade various polymers and the function of multiple enzymes in the degradation of MPs. Also, the role of different extracellular and intracellular enzymes in biological degradation of MPs is discussed.
