This study evaluated the antifouling potential of pyrrolo compound (PC) from the sponge-associated bacterium <em>Halobacillus kuroshimensis</em> against the barnacle <em>Amphibalanus reticulatus</em> larval survival, metamorphosis and settlement in the laboratory. The successful concentrations were also subjected to field based static immersion tests to study the efficacy of the PC extract on macrofouling settlement. Results showed decreased naupliar survival and affected larval metamorphosis in a dose-dependent manner, with varying sensitivity among developmental stages. Higher PC concentrations significantly reduced cyprid yield and settlement, with over 50% of cyprid larvae failing to settle at concentrations of 1300 μg/ml and above. Field experiments confirmed a steady decline in barnacle settlement on PC-treated coupons, with less than 50% settlement observed at concentrations of 500–2000 μg/ml over 50 days. The LC₅₀/EC₅₀ ratio for nauplius N-II was 1.11, with higher ratios observed in later stages and for the cypris (1.66), suggesting moderate toxicity and a narrow margin of safety. These ratios suggest barnacle settlement inhibition occurring through a toxic mechanism. The results demonstrate the compound's ability to disrupt barnacle settlement, but also raise concerns about its environmental impact (long-term usage), particularly the potential risks to non-target species before using the compound in real-world antifouling applications. Despite higher concentrations used compared to previous reports, PC shows potential as an effective natural antifouling compound.</div></div>","PeriodicalId":13643,"journal":{"name":"International Biodeterioration & Biodegradation","volume":"197 ","pages":"Article 105960"},"PeriodicalIF":4.1,"publicationDate":"2024-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746238","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}

In this paper, Differential Scanning Calorimeter (DSC), Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES), Liquid Chromatography-Mass Spectrometry (LC-MS) and characteristic components analysis were used to analyze the biodeterioration process and mechanism of the chrome-tanned leather. Feasible strategies to improve the biodeterioration prevention effect were explored in detail from the aspect of tanning-basification processes and the selection of fungicides. The results showed that molds grow and reproduce by using the available proteins, fats and carbohydrates in the chrome-tanned leather as nutrient resources, metabolizing and secreting alkaline substances such as histamine and spermine, and proteases, simultaneously. The macromolecular organic matter was hydrolyzed into small molecular substances and provided nutrients for microorganisms, meanwhile, the increase of environmental pH caused the dechroming of tanned collagen fiber, accelerating the degradation of collagen fiber, making tanned leather more easily destroyed. Furthermore, the use of a proper amount of MgO for basification was not likely to cause a continuous increase in the pH of the chrome-tanned leather during storage, and the pH of the leather eventually stabilized at about 4.0 during long-term storage. Additionally, the use of 100 mg/L of fungicides MIT, CMIT, IPBC and OIT can effectively kill molds and continuously inhibit the development of mold spores during the storage procedure, which is an effective way to solve biodeterioration of chrome-tanned leather. Hence, this study provides theoretical support for effectively solving the problem of biodegradation of chrome-tanned leather caused by mold growth and reproduction, which could reduce the hazard to the environment while reducing the production cost of tanneries and improving the economic benefits.</div></div>","PeriodicalId":13643,"journal":{"name":"International Biodeterioration & Biodegradation","volume":"197 ","pages":"Article 105961"},"PeriodicalIF":4.1,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142722398","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}

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}

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.
