Preserving and utilizing microbial diversity for innovation and sustainability
Lima, NelsonMicrobial culture collections have been fundamental to microbiology since their inception in the late nineteenth century. Initiated by Professor Král, the collections preserve and distribute microbial strains, enabling scientific advancements. Over time, they evolved into microbiological resource centres, integrating taxonomic expertise and adhering to international legal frameworks and quality management syste...
MIRRI-ERIC's position on the recent evolution of the international code of nome...
Aznar, Rosa; Mistou, Michel-Yves; Rahi, Praveen; Legras, Jean-Luc; Boroduske, Anete; Stefaniu, Amalia; Lima, Nelson; Karagouni, Amalia D.The current state of prokaryotic nomenclature is increasingly complex, with ongoing debates arising from the rejection of the 2020 proposal to amend the International Code of Nomenclature of Prokaryotes (ICNP) to accept genome sequences as nomenclatural types. This decision subsequently led to the development of the SeqCode, an alternative code based on genome sequences as types for yet-uncultured microorganism...
Novelties in Funalia and the status of Fomitella (Polyporaceae, Basidiomycota)
Targino de Oliveira, Virton Rodrigo; Assis Alves, Paulo Roberto de; Lima-Júnior, Nelson Correia de; Santos, Carla Isabel Arcanjo; Lima, NelsonDuring studies on the taxonomical delimitation of some species of Funalia, some inconsistencies were observed in the genus. Based on morphological and phylogenetic analyses, the generic type Fomitella supina was positioned within the Funalia clade; thus, the synonymization of the genus and the new combination of Funalia supina are proposed. Funalia glabrorigens is also combined in the genus, while F. hainanensi...
A comprehensive method for the sequential separation of extracellular xylanases...
Rodríguez-Sanz, Andrea; Fuciños, Clara; Soares, Célia Maria Gonçalves; Torrado, Ana M.; Lima, Nelson; Rúa, María L.Several fungal species produce diverse carbohydrate-active enzymes useful for the xylooligosaccharide biorefinery. These enzymes can be isolated by different purification methods, but fungi usually produce other several compounds which interfere in the purification process. So, the present work has three interconnected aims: (i) compare -xylosidase production by Fusarium pernambucanum MUM 18.62 with other crop ...
Creating community of microbiology-related professionals through the MIRRI Coll...
Zuzuarregui, A.; Lima, Nelson; Soares, Luís; Aznar, R.; Almeida, L.; IS_MIRRI21 ConsortiumMIRRI-ERIC supports the biosciences scientific community and bioindustries by providing a single point of access to microbial related services, the MIRRI Collaborative Working Environment (CWE, www.mirri.org). The CWE facilitates the access to the broadest range of high-quality microorganisms, their derivatives, associated data and services, and it is complemented with a forum of experts created to share and ge...
Microbial culture collections: strains, services, projects and consortia to und...
Lima, NelsonOver the years, microbial culture collections (CCs) have been providing services to the scientific community, acting as reservoirs and providers of microorganisms, including their living cells, genomes, and information, being key players in the development of new and more sustainable products, compounds, and practices. When all these activities are performed under a legal framework and within a quality manageme...
Preservation methods in isolates of Sporothrix characterized by polyphasic appr...
de Souza Rabello, Vanessa Brito; Corrêa-Moreira, Danielly; Santos, Cledir; Abreu Pinto, Tatiana Casto; Procopio-Azevedo, Anna Carolina; Boechat, JéssicaSporotrichosis is a subcutaneous mycosis with worldwide distribution and caused by eight pathogenic species of the Sporothrix genus. Different ex situ preservation methods are used around the world to maintain the survival, morphophysiological and genetic traits of fungal strains isolated from patients with sporotrichosis for long terms. The main aim of the present study was to evaluate the survival, phenotypic...
Bioprospection of antibiotics and biofilm inhibitors from under-exploited filam...
Correia, J.; Borges, A.; Simões, M.; Soares, Célia; Lima, Nelson; Simões, Lúcia ChavesIn the past century, millions of lives were saved by antibiotics, which treat some of the historically more deadly diseases. However, bacteria may quickly develop antibiotic resistance and the speed of development of new drugs has decreased significantly in the last decades. Filamentous fungi have a great potential for novel antibiotic discovery, given their vast, largely unexplored metabolome. The One Strain M...
Evaluation of lipid extraction methods from Antarctic filamentous fungi
Gallardo, V.; Sepúlveda, M.; Barría, E.; Cayún, Y.; Dias, Nicolina Marques; Lima, Nelson; Cornejo, P.; Santos, Carla Isabel ArcanjoPurpose: The benefits of natural compounds have been studied for decades for the development of new technologies to answer the global change challenges. In order to develop these new technologies, lipids represent a great class of bioactive molecules. However, the research on lipids and their applications still present gaps about new sources as well as on the extraction methods. Filamentous fungi found in Antar...
Aflatoxins and ochratoxin A contamination during Merkén Pepper Powder productio...
Costa, Jéssica; Santos, Carla Isabel Arcanjo; Soares, Célia Maria Gonçalves; Lima, Nelson; Santos, CledirBerry fruits of Capsicum annuum L. cv. "Cacho de Cabra are used for the manufacture of a traditional pepper powder known as Merkén, which is a Chilean spicy widely consumed at national level in Chile and also exported to different countries. Merkén contamination with Aflatoxins (AFs) and Ochratoxin A (OTA) is a main concerning for local producers and national and worldwide consumers. In the present study, AFs a...
