Investigation of Microbial Consortia: From Fundamental to Applied Results, From Established to Novel Production Systems
No full textSoil microbiology has long been a rich source of novel scientific discoveries and continues to be a key contributor to industrial applications. In this regard, fungi have played multifaceted roles, from promoting plant growth to serving as prolific producers of antimicrobial compounds. Despite significant advances, the full potential of fungal–plant interactions remains underexplored, particularly in the case of the aromatic and medicinal plants such as Lavandula, and the microfungal communities associated with its root system. In this work, we demonstrated that the characterization of microfungal community in association with Lavandula led not only to taxonomical advancements by expanding established fungal phylogenies, but also to the discovery and characterization of novel antimicrobial compounds such as antifungal proteins (AFPs). A comprehensive methodological pipeline was employed, beginning with fungal isolation, morpho-molecular species-level identification, biodiversity assessment, and taxonomic classification. These were followed by protein production and purification, biochemical and structural characterization, and genome engineering techniques. This integrative framework enabled the translation of basic mycological discoveries into biotechnologically relevant results.
Ecological analyses revealed that climate ecosystems, rather than plant species identity, were the predominant determinants affecting microfungal community composition. Lavander-associated fungal communities displayed strong site-specific variability, with alpha diversity gradually declining from Mediterranean to continental climates while beta diversity revealed complex patterns influenced by agricultural practices, highlighting the need for further research to harness their ecological and agricultural potential. Additionally, two novel fungal species belonging to the genera Rasamsonia and Talaromyces were identified and described for the first time. While the thermophilic Rasamsonia lemurum shares the genus' typical heat tolerance but exhibits rare globose conidia, Talaromyces montemartinii displays unusual thermotolerance and reduced sporulation, together highlighting how thermal adaptation and morphological divergence shape fungal biodiversity. Moreover, we reported the identification, production, and functional characterization of AfAfpC, a novel AFP from the Lavandula soil isolate Aspergillus fischeri. AfAfpC exhibited moderate-to-strong inhibitory activity against filamentous fungi, despite its near-neutral isoelectric point. CRISPR-Cas9-mediated deletion of the afafpC gene revealed that it is dispensable for growth and development. These findings enhance our understanding of AFP diversity and establish A. fischeri as a promising platform for the development of sustainable antifungal applications. Finally, the incorporation of the developed know-how was designed and started to be implemented in an innovative project uniting aquaculture systems with Artificial Intelligence. Potential future research directions might see other, novel species descriptions deriving from similar working guidelines, as well as new antimicrobial compounds discovered and investigated in their biotechnological potential

Bank Recovery and Resolution: An Italian Point of View
No full textThe author examines the main legal aspects of the Single Resolution Mechanism as provided by the Directive no. 59 of 15 May 2014 and the Regulation no. 806 of 15 July 2014. After finding a definition tailored on the term “resolution”, the author pays particular attention to some important aspects as: recovery plan, preventive measures, early intervention measures and the resolution. As regards the latter one, the author examines especially all resolution instruments like the “sale of business tool”, the “bridge institution tool”, the “asset separation tool” and the “bail-in tool” noting in particular the effects of the application of those tools on stakeholders and their impact on the Italian banking legal system. Finally, considering the drastic nature of the last tool, the author put in the light an important doctrinal debate, i.e. the compatibility of that tool (and more generally the provisions of the Directive) with the article 47 of the Italian Constitution
Fungal Arsenic Tolerance and Bioaccumulation: Local Strains from Polluted Water vs. Allochthonous Strains
No full textThe paper deals with the possible use of fungi to decontaminate polluted waters. Specifically, the focus is the selection of the most promising fungal strain capable of bioaccumulating arsenic, which is a globally widespread environmental contaminant. To this aim, allochthonous fungal strains from the ColD UNIGE JRU MIRRI strains collection were selected. Their capability to survive and accumulate this kind of pollutant was evaluated and compared with that of an autochthonous fungi set directly isolated from the arsenic polluted water. A preliminary screening at various concentrations of arsenic (0, 200, 400, 800, 1600 μg L−1) revealed that the best performing strains were Aspergillus niger and Penicillium expansum among the autochthonous strains and Aspergillus niger and Penicillium expansum among the allochthonous strains. Moreover, all the strains were subjected to bioaccumulation tests at a 1600 μg L−1 concentration. Local and allochthonous fungal strains showed different behaviors: the allochthonous strains grew rapidly and in a sustained way but without expressing any bioaccumulation activity. On the contrary, the indigenous fungi, despite a moderate growth, showed a good bioaccumulation capacity (in particular, Aspergillus niger). The results highlight the importance of employing native strains isolated from contaminated matrices to make a mycoremediation protocol more efficient
