This work introduces the IST-Yeasts Culture Collection (IST-Yeasts CC) – a new biological resource assembled and preserved over the past few years by Isabel Sá-Correia‘s research group, with the key involvement of Madalena Matos and Mónica Fernandes, at the Biological Sciences Research Group, iBB-Institute for Bioengineering and Biosciences, Departamento de Bioengenharia, Instituto Superior Técnico (University of Lisbon). The collection is dedicated to non-conventional “blue” yeasts isolated from (micro)algae-associated environments in Portugal.

It currently holds 115 yeast strains, mostly from the phylum Basidiomycota (92%), with a strong representation of the genus Rhodotorula, alongside species from Cystobasidium, Vishniacozyma, Moesziomyces, Sporobolomyces, Naganishia, and Ascomycota members such as Meyerozyma, Yamadazyma, and Cyberlindnera.

Initial functional screening revealed that these strains can produce carotenoids, lipids, riboflavin, biosurfactants, bioemulsifiers, and auxins, as well as growing on a wide range of carbon sources.

These characteristics highlight their biotechnological potential within the circular bioeconomy and sustainable bioprocesses, positioning them as promising sources of bioactive natural products.

By providing access to a diverse collection of marine-associated yeasts, the IST-Yeasts CC supports the development of innovative solutions in marine biotechnology and marine drug discovery, including the design of more resilient and high-performance algal cultivation systems through targeted co-cultivation strategies.

This work was developed within the scope of the Pacto da Bioeconomia Azul, funded by Portugal’s Recovery and Resilience Plan (PRR) and the European Union – Next Generation EU

Screening of Marine Bacteria for Lipase Activity https://ibb.tecnico.ulisboa.pt/screening-of-marine-bacteria-for-lipase-activity/ Sat, 04 Jul 2026 13:03:14 +0000 https://ibb.tecnico.ulisboa.pt/?p=15161 Multiple approaches are available for the identification of novel microbial lipases. Despite the growing importance of metagenomics in bioprospecting, limitations in recombinant protein expression, in particular for lipases, remain. In a recently published paper, Luís C. de Sousa and Carla C. C. R. de Carvalho  and a former MSc student, Ana J. Caeiro (currently PhD student at UGent), demonstrate that culture-based bioprospecting approaches are still valuable. Six isolates presenting high activity were characterized as whole-cell biocatalysts. Genomic analyses of two Gram-negative lipase-producing isolates revealed the presence of several hypothetical genes encoding for lipolytic enzymes, including outer cell-bound enzymes, predicted through the application of machine-learning tools.

Halophilic Archaea reveal a hidden talent https://ibb.tecnico.ulisboa.pt/halophilic-archaea-reveal-a-hidden-talent/ Thu, 02 Jul 2026 18:25:20 +0000 https://ibb.tecnico.ulisboa.pt/?p=15158 For decades, extremely halophilic archaea – microorganisms that thrive in salt concentrations far exceeding seawater – have been valued mainly for their extraordinary resilience. A newly published study, co-authored by Carla C. C. R. de Carvalho of iBB’s 2BRG group, suggests these extremophiles have another trick up their sleeve.

The researchers collected brine and sediment samples from hypersaline sites scattered across Eurasia through the salt lakes of Russia’s Kulunda Steppe, the marine salterns of Samouco in Portugal and Trapani in Italy, and the salt production fields of Nha Trang and Cam Ranh in Vietnam.

Using enrichment cultures, they went looking for organisms able to grow on hyaluronic acid as their sole source of carbon and energy: a glycosaminoglycan best known for its structural role in skin, joints and connective tissue, and prized by the cosmetics and biomedical industries.

They found it. The isolates that thrived on hyaluronic acid turned out to belong to new species within the genera Natronoarchaeum and Haloarcula, the first haloarchaea ever shown capable of using this compound as an energy source. It’s a small discovery with a big implication: even within one of biology’s most extensively studied groups of extremophiles, entire metabolic pathways were still waiting to be found, with potential relevance for biotechnological applications such as the biodegradation of hyaluronic-acid-based biopolymers.

The study is published in Frontiers in Microbiology: doi: 10.3389/fmicb.2026.1846936

Multi-omics characterization of developing forebrain organoids unravels the dynamic molecular events of Rett syndrome pathogenesis https://ibb.tecnico.ulisboa.pt/multi-omics-characterization-of-developing-forebrain-organoids-unravels-the-dynamic-molecular-events-of-rett-syndrome-pathogenesis/ Fri, 12 Jun 2026 16:53:21 +0000 https://ibb.tecnico.ulisboa.pt/?p=15125 A team of researchers from iBB, including Margarida Diogo and Tiago Fernandes, has contributed to advancing our understanding of Rett syndrome (RTT), a rare neurodevelopmental disorder primarily caused by mutations in the MECP2 gene. Although RTT results from alterations in a single gene, the molecular events that drive its development remain poorly understood.

Using patient-derived brain organoids and an integrated multi-omics approach, the researchers mapped how changes in gene and protein expression unfold throughout early brain development. Their work revealed disruptions in key biological processes involved in neuronal development and communication, particularly in GABAergic signalling, while also identifying long non-coding RNAs and imprinted genes as potential contributors to RTT pathology.

By providing a detailed view of the molecular mechanisms underlying Rett syndrome, this study offers new clues into how the disorder develops and highlights promising avenues for future research into targeted therapies that could improve the lives of individuals affected by RTT.

Lipase-assisted removal of spin finishes: What if you could strip the lubricants off synthetic textiles without solvents, and get the same result? https://ibb.tecnico.ulisboa.pt/lipase-assisted-removal-of-spin-finishes-what-if-you-could-strip-the-lubricants-off-synthetic-textiles-without-solvents-and-get-the-same-result/ Mon, 01 Jun 2026 10:00:13 +0000 https://ibb.tecnico.ulisboa.pt/?p=15077 The challenge: The textile industry relies on fatty acid ester lubricants such as spin finishes and sizes to manufacture synthetic fibres. Removing these residues conventionally depends on solvent-based processes, which carry significant environmental and health burdens.

What we did: Researchers Luís C. de Sousa and Carla C. C. R. de Carvalho (2BRG), within the EU-funded FuturEnzyme project, demonstrated a greener alternative. Using lipase enzymes produced by project partners and real polyamide-with-elastane textiles supplied by an industrial partner, the team developed both the biocatalytic hydrolysis step and the accompanying washing process.

The outcome that matters: Enzymatic treatment paired with optimized washing conditions removed spin finishes with performance comparable to existing solvent-based methods, proving that a biological process can match the industry standard while offering a cleaner profile.

Why it’s significant:

  • Environmental impact: Replacing solvents with enzymes points toward lower-toxicity, more sustainable textile processing.
  • Industrial relevance: Validation on commercial materials and conditions, not just lab samples, shortens the path to real-world adoption.
  • Collaborative value: A working pipeline spanning enzyme producers, academic researchers, and industrial partners shows the FuturEnzyme model delivering applied results.

The bigger picture: This work moves enzyme-based textile cleaning from concept to credible competitor, supporting the textile sector’s transition toward more sustainable, bio-based manufacturing.

Ana M. Melo co-authors Nature Methods study advancing the understanding of disordered proteins https://ibb.tecnico.ulisboa.pt/ana-m-melo-co-authors-nature-methods-study-advancing-the-understanding-of-disordered-proteins/ Wed, 15 Apr 2026 14:46:05 +0000 https://ibb.tecnico.ulisboa.pt/?p=15001 What if one of biology’s most fundamental rules no longer holds?

For decades, we’ve understood proteins through a simple logic: sequence → structure → function.
But not all proteins follow the rules.

A new study published in Nature Methods challenges this view by focusing on intrinsically disordered proteins (IDPs), proteins that don’t settle into a single structure, but constantly shift between many. Elusive, dynamic and deeply involved in processes like cell regulation, cancer, and neurodegenerative diseases.

The work, “Towards a Unified Framework for Determining Conformational Ensembles of Disordered Proteins,” brings together researchers from Europe and the US, including Ana M. Melo affiliated with Institute for Bioengineering and Biosciences

Ana Melo applies single-molecule FRET (smFRET), a technique that tracks how individual protein molecules change shape in real time. Not averages. Not snapshots. But motion, as it happens. This capability is rare. The smFRET instrumentation available at Técnico is unique in Portugal, placing it among a small number of laboratories in Europe able to probe protein dynamics at this level.

By combining experimental approaches like smFRET with computational modelling, the study proposes a unified way to describe these constantly shifting proteins.

Because when structure is no longer fixed, biology becomes less predictable.
And understanding that complexity is where the next breakthroughs will come from.

From lab to fabric: improving how lipase performance is evaluated for textile applications https://ibb.tecnico.ulisboa.pt/from-lab-to-fabric-improving-how-lipase-performance-is-evaluated-for-textile-applications/ Fri, 20 Mar 2026 19:29:13 +0000 https://ibb.tecnico.ulisboa.pt/?p=14982 Assessing enzyme performance under real industrial conditions remains a key barrier to the adoption of biocatalysts in textile processing.

Researchers from iBB,  Luís C. de Sousa and Carla C. C. R. de Carvalho, developed a new analytical approach combining methylation and silylation to evaluate how effectively lipases act on textile materials.

Crucially, the approach was applied directly to textile substrates, including materials relevant to industrial settings such as spin-finished fabrics and stained textiles. This enabled the evaluation of enzyme performance under application-relevant conditions.

The results show that relying on a single method can overlook important aspects of enzyme activity. In contrast, combining methylation and silylation provides a more complete understanding of both fatty compound removal and enzymatic action.

By enabling the direct assessment of enzymes on textile materials, this work offers a practical tool to support the selection and optimisation of lipases for industrial processes, including more efficient detergent formulations.

New European Project BIO4PAK – Biodegradable Bio-based Bioactive Packaging Technology for Supporting Food Safety https://ibb.tecnico.ulisboa.pt/14949-2/ Mon, 26 Jan 2026 15:52:26 +0000 https://ibb.tecnico.ulisboa.pt/?p=14949 The EU-funded BIO4PAK has officially launched, bringing together leading research institutions across Europe to develop next-generation sustainable food packaging solutions. The initiative, coordinated by University of Lodz, responds to the urgent need to replace conventional fossil-carbon plastics with bio-based, biodegradable, and environmentally safe materials while maintaining food safety and performance standards.

BIO4PAK combines interdisciplinary research in polymer science, microbiology, biotechnology, and materials engineering to create intelligent packaging that not only protects food but also offers environmental benefits and circularity throughout its lifecycle. A notable focus of the project is the development of phage-based antimicrobial coatings using an innovative PhagTec delivery system designed to trigger antimicrobial action in the presence of specific bacterial pathogens such as Salmonella, Campylobacter, and Listeria, reducing contamination and improving shelf life.

Participating researchers from IST‑ID Associação do Instituto Superior Técnico and iBB including Nuno P. Mira, Ana Azevedo, and Jorge H. Leitão, contribute to the project’s scientific development, focusing on nature-inspired, biodegradable materials suited for practical use in the food industry. According to the Instituto Superior Técnico, the aim is to develop packaging that goes beyond passive containment to act as a “sentinel” material, responding functionally when biological threats are detected.

The international consortium also includes University of Gdansk, Wrocław University of Science and Technology, Spanish National Research Council (CSIC), TalTech – Tallinn University of Technology, and Hasselt University, uniting expertise in agriculture, industry, regulatory frameworks, life-cycle assessment, and advanced materials.

The project’s kick-off meeting, held on 15–16 January, marked the official start of collaborative activities and strategic planning among partners. BIO4PAK also explores synergies within the EIC Circular Bio‑based Plastics Portfolio, underscoring the importance of cooperation to accelerate the transition to sustainable and circular food packaging solutions.
