The Microbial Ecology and Evolution Research Group seeks to understand the causes and consequences of microbial diversity in nature. We apply novel molecular technologies to unravel the composition and diversity of microbial consortia in natural settings and microcosms. This enables us to investigate the driving forces that shape microbial community structure in the open environment and under experimental control.

[PT] A coleção MicroEcoEvo (Microbial Ecology and Evolution Research Group), do parceiro Instituto Superior Técnico, marcou presença no Marine Host-Microbe Symbioses Symposium, em Padua, na Itália.

Tina Keller-Costa apresentou numa comunicação oral a descoberta de novas enzimas de bactérias simbióticas de corais que degradam quitina, o polímero natural mais abundante do oceano 🌊. Estas enzimas revelam adaptações únicas ao ambiente marinho e ajudam a compreender de que forma os microrganismos contribuem para a reciclagem e o equilíbrio ecológico dos corais 🪸🤝🧫.

Joana Couceiro apresentou, sob a forma de um poster, um estudo que demonstra que a variação das condições de cultivo de bactérias permite cultivar uma maior diversidade de bactérias associadas a corais, revelando novas espécies e estirpes bioativas com elevado potencial para a biotecnologia azul 🧪.

[EN] The MicroEcoEvo collection (Microbial Ecology and Evolution Research Group), from our partner Instituto Superior Técnico, was represented at the Trends in Marine Host-Microbe Symbioses Symposium in Padua, Italy.

Tina Keller-Costa delivered an oral presentation on the discovery of new enzymes from coral symbiotic bacteria that degrade chitin, the most abundant natural polymer in the ocean 🌊. These enzymes reveal unique adaptations to the marine environment, helping us to understand how microorganisms contribute to the recycling processes and ecological balance of corals 🪸🤝🧫.

Joana Couceiro presented a poster on a study that shows that varying bacterial cultivation conditions promotes the growth of a greater diversity of coral-associated bacteria, uncovering new species and bioactive strains with significant potential for blue biotechnology 🧪.

[PT] A coleção MicroEcoEvo (Microbial Ecology and Evolution Research Group), do parceiro Instituto Superior Técnico, marcou presença na Conferência Internacional para Jovens Investigadores Marinhos (ICYMARE) em Bremerhaven, na Alemanha.

A investigadora Daniela Silva apresentou, sob a forma de um poster, os resultados do trabalho desenvolvido acerca do estudo da família bacteriana Endozoicomonadaceae. Estes microrganismos são muito comuns no Oceano e desempenham um papel essencial nos ecossistemas marinhos.

🌊🔬 Este estudo mostrou que estas bactérias têm uma enorme versatilidade: participam nos ciclos do carbono e do azoto, produzem vitaminas e vivem em simbiose com outros organismos.
É fundamental compreender melhor estas interações para perceber o impacto destas bactérias na saúde dos ecossistemas marinhos e até explorar o seu potencial na engenharia de microbiomas marinhos. 🌍✨

[EN] The MicroEcoEvo collection (Microbial Ecology and Evolution Research Group), from our partner Instituto Superior Técnico, was showcased at the International Conference for Young Marine Researchers (ICYMARE) in Bremerhaven, Germany.

Researcher Daniela Silva presented a poster that highlights the results of her work on the study of the bacterial family Endozoicomonadaceae. These microorganisms are widespread in the Ocean and play an essential role in marine ecosystems.

🌊🔬 This study revealed a remarkable versatility of these bacteria: they participate in carbon and nitrogen cycles, produce vitamins, and live in symbiosis with other organisms.

Understanding these interactions is key to assessing bacteria's impact on the health of marine ecosystems and exploring their potential in marine microbiome engineering. 🌍✨

[PT] O 𝘁𝗲𝘀𝗢𝘂𝗿𝗼 𝘀𝘂𝗯 𝗔𝘇𝘂𝗹 desta semana é a estirpe bacteriana 𝘔𝘢𝘳𝘪𝘵𝘢𝘭𝘦𝘢 sp. EG82.

🧫🪸Esta estirpe foi isolada do octocoral 𝘌𝘶𝘯𝘪𝘤𝘦𝘭𝘭𝘢 𝘨𝘢𝘻𝘦𝘭𝘭𝘢 (Studer, 1901), que foi amostrado ao largo da costa de Faro, em Portugal.

O isolamento desta bactéria teve como meio de preservação marinho a taurina, que é um aminoácido frequentemente utilizado em bebidas energéticas. Em ambientes marinhos, a taurina atua como uma fonte significativa de energia e nutrientes para alguns microrganismos.

🔍🌍Este tesouro possui genes responsáveis pela produção de ectoína, uma substância com aplicações farmacêuticas, também importante para a manutenção da saúde dos corais em situações de stress ambiental.

Até agora, eram conhecidas apenas quatro espécies de 𝘔𝘢𝘳𝘪𝘵𝘢𝘭𝘦𝘢. No entanto, análises genéticas e filogenómicas indicam que a estirpe 𝘔𝘢𝘳𝘪𝘵𝘢𝘭𝘦𝘢 sp. EG82 representa uma nova espécie para a ciência.

💡 Este tesouro pertence à coleção MicroEcoEvo (Microbial Ecology and Evolution Research Group) do Instituto de Bioengenharia e Biociências do Instituto Superior Técnico.

[EN] The 𝘁𝗲𝘀𝗢𝘂𝗿𝗼 𝘀𝘂𝗯 𝗔𝘇𝘂𝗹 of this week is a strain of the bacteria 𝘔𝘢𝘳𝘪𝘵𝘢𝘭𝘦𝘢 sp. EG82.

🧫🪸 This strain was isolated from the octocoral Eunicella gazella (Studer, 1901), collected off the coast of Faro, Portugal.

The isolation of the bacteria had a preservation marine medium based on taurine, an amino acid commonly found in energetic drinks. In marine environments, taurine acts as a significant source of energy and nutrients for some microorganisms.

🔍🌍 This microbial treasure has genes involved in the production of ectoine - a compound with pharmaceutical applications, which is important for the maintenance of the coral health under environmental stress conditions.

So far, only four species of 𝘔𝘢𝘳𝘪𝘵𝘢𝘭𝘦𝘢 were known to science. Nonetheless, genetic and phylogenomic analyses suggest that the strain 𝘔𝘢𝘳𝘪𝘵𝘢𝘭𝘦𝘢 sp.EG82 represents a new species.

💡 This treasure belongs to the MicroEcoEvo collection at the Institute of Bioengineering and Biosciences - Instituto Superior Técnico.
