The meeting gathered together experts in fungi, bacteria, and viruses with backgrounds in climate science, genomics, terrestrial and aquatic ecosystems, and human health, spanning research, industry, conservation, and policy. Key themes included: how to communicate the importance of microbes, how to conserve microbes themselves, and how microbes could be integrated into existing conservation. The primary outcome was the launch of the IUCN Species Survival Commission-Microbial Conservation Specialist Group.

A total of six fungal isolates were recovered from corn-, rice-, and wheat-based infant foods, representing four genera: Aspergillus (A. niger, A. versicolor, A. terreus), Mucor, Rhizopus, and Saccharomyces cerevisiae. Toxigenicity assays revealed that A. versicolor and A. niger produced mycotoxins, while aflatoxin quantification via HPLC detected total aflatoxin concentrations ranging from 0.56 ± 0.04 µg/g to 9.20 ± 0.02 µg/g across the samples.100 environmental samples yielded 23 pigmented yeasts, from which three distinct Rhodotorula strains (YP1, YP2, YP3) were selected based on robust pigment production and growth characteristics. Carotenoid pigments were extracted using acetone and petroleum ether, with storage optimised under dark conditions at 4°C. Protein profiling by SDS-PAGE revealed that all three yeast isolates shared similar banding patterns. Antifungal activity of the yeast-derived pigments against toxigenic Aspergillus isolates shows YP3 exhibited the strongest inhibition, producing zones of 21 mm against A. versicolor and 19 mm against A. niger, more than antifungal agents (fluconazole, ketoconazole, itraconazole, amphotericin B), which showed limited activity (1-5 mm inhibition zones).","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"2 4","pages":"qvaf028"},"PeriodicalIF":0.0,"publicationDate":"2025-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13375335/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative insights into nitrogen-fixing efficiency, metabolite production, and strategies to mitigate cyanotoxin-related risks are discussed alongside emerging applications in functional foods, nutraceuticals, and sustainable agriculture. Its nutritional profile and adaptability position N. commune as a low-impact alternative within integrated food and health systems. Additionally, the review explores its significance in cultural traditions, biotechnology, and environmental remediation. Despite its promise, challenges remain, including variable metabolite profiles and safety concerns related to neurotoxins such as β-N-methylamino-L-alanine, necessitating targeted strain selection and regulatory frameworks. By integrating advances in genetic engineering, circular bioeconomy strategies, and community-centred approaches, N. commune could become a cornerstone of climate-smart agriculture, sustainable food systems, and global health solutions.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"2 4","pages":"qvaf025"},"PeriodicalIF":0.0,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13375348/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples of outbreaks of food and water-related infection possibly related to climate change are reviewed here along with other emerging issues. For instance, increasing sea temperatures are contributing to an increase in Vibrio spp. in the aquatic environment and rising cases of foodborne infections and as well resulting in new patterns of fish-related diseases in consumers, such as Ciguatera fish poisoning. Warmer and wetter climactic conditions are also contributing to an increase in mycotoxin production and there is a growing concern that the drive towards more sustainable food supplies and novel alternative protein sources may lead to the emergence of novel threats. Future areas of possible concern ('unknown unknowns') are climactic conditions driving the appearance of highly virulent foodborne pathogens, increased threats due to increases in noxious seaweed in coastal areas in the Caribbean and Mexico, and dust storms spreading fungal and bacterial pathogens over vast areas globally. To ensure public safety in the future these new threats need to be recognized, and appropriate mitigation measures put in place by the food industry-which may require a re-evaluation of many established HACCP (Hazard Analysis and Critical Control Points) plans.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"2 4","pages":"qvaf019"},"PeriodicalIF":0.0,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13375361/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While commercial rhizobial inoculants have been utilized as biofertilizers for leguminous crops, their effectiveness can be limited by poor adaptation to local conditions. Here, we call attention to the opportunity of locally adapted rhizobial inoculants to contribute to sustainable agriculture and nutrition security in the Sahel Region. Certain indigenous rhizobial strains across the African continent have demonstrated superior performance in nodulation, legume crop yields, and/or resilience to abiotic stresses compared to commercial inoculants. We propose a comprehensive framework that emphasizes (1) the selection of indigenous strains optimized for nitrogen fixation and abiotic stress tolerance, (2) matching inoculants with regionally important and underutilized legumes, and (3) ethical and broader considerations for developing inoculant formulations to enhance field performance. We stress that locally adapted rhizobial strains can contribute to enhanced nutrition security through improved legume crop yields, improve climate resilience, and potentially promote agricultural sustainability through reduced reliance on synthetic fertilizer inputs in the Sahel, with potential applications for other nitrogen-deficient regions globally. However, to be sustainable, this approach requires community-based participatory research, supportive policy frameworks, and investment in local capacity building.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"2 4","pages":"qvaf023"},"PeriodicalIF":0.0,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13375306/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we did not find a core resistome, but found that the predominant and most diverse mechanisms of Anti-Microbial Resistance (AMR) in the dust samples were antibiotic target alteration and antibiotic efflux, accounting for ∼70% of cumulative RPKMs detected, potentially representing a compromise between the certainty of working and energy investment required.

This study investigated the effects of three crop rotation systems, wheat after wheat, wheat after medicago, and wheat after canola on the soil fungal and bacterial communities, in a regenerative agriculture system, in the Western Cape, South Africa, following a record-breaking drought (2015-19). Utilizing 16S rRNA and ITS (Internal transcribed spacer region) targeted amplicon sequences, soil-geochemical properties, and qPCR (Quantitative Polymerase Chain Reaction) analyses, it was found that crop rotations had little significant effect on the alpha-diversity between different crop-rotation systems . Medicago and wheat had the most similar communities, with canola diverging from the other rotation systems. Host driven selection was prevalent in the rhizosphere microbiome during the wheat growth period, across treatments and farms. After senescence, the microbiome composition transitioned from the wheat-selected communities towards communities consisting of saprotrophs and yeasts. qPCR analyses of nitrogen-associated genes revealed that genes for nitrification (amoA) and denitrification (nirK) increased during fertilizer application events, whereas genes associated with nitrogen fixation (nifH), denitrification (nirS), and nitrification (nxrB) increased throughout the season. Genera associated with drought and halotolerance were enriched in all samples.","PeriodicalId":516860,"journal":{"name":"Sustainable microbiology","volume":"2 4","pages":"qvaf020"},"PeriodicalIF":0.0,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13375304/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148709204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
