From lignocellulosic residues to protein sources: insights into biomass pre-tre...
Vera dos Anjos, Isabela; Coelho, Natacha; Duarte, Hugo; Proença, Diogo Neves; Duarte, Maria F.; Jorge de Barros, Raúl José; Raposo, SaraWith the global population steadily rising, the demand for sustainable protein sources has become increasingly urgent. Traditional animal- and plant-based proteins face challenges related to scalability, resource efficiency, and environmental impact. In this context, single-cell protein has emerged as a promising alternative. Derived from microorganisms such as algae, bacteria, fungi, and yeast, single-cell pro...
Potential protective role of amphibian skin bacteria against water mold saprole...
Costa, Sara; Proença, Diogo Neves; Alves, Artur; Morais, Paula V.; Lopes, IsabelAmphibian populations have experienced a severe decline over the past 40 years, driven primarily by environmental pollution, habitat destruction, climate change, and disease. This work reports, for the first time, saprolegniosis in Pelophylax perezi egg masses and saprolegniosis in amphibians in Portugal. After isolation and phylogenetic analysis, the pathogen was identified as Saprolegnia australis. Following ...
The Role of Bacterial Polyhydroalkanoate (PHA) in a Sustainable Future: A Revie...
Vicente, Diogo; Proença, Diogo Neves; Morais, Paula V.Environmental challenges related to the mismanagement of plastic waste became even more evident during the COVID-19 pandemic. The need for new solutions regarding the use of plastics came to the forefront again. Polyhydroxyalkanoates (PHA) have demonstrated their ability to replace conventional plastics, especially in packaging. Its biodegradability and biocompatibility makes this material a sustainable solutio...
Biological Control of Phytopathogens: Mechanisms and Applications
Hartmann, Anton; Proença, Diogo NevesAccording to the inherent ecological mechanisms within community structures, organismic interactions are mediated by chemical structures and signaling molecules as well as enzymatic activities targeting the vital activities of microbial competitors [...].
The Role of Serratomolide-like Amino Lipids Produced by Bacteria of Genus Serra...
Marques-Pereira, Catarina; Proença, Diogo Neves; Morais, Paula V.Bursaphelenchus xylophilus, also known as pinewood nematode (PWN), is the pathogenic agent of pine wilt disease (PWD), which affects pine trees around the world. Infection spread globally through international wood commerce and locally by vector beetles, threatening the wood world economy. As climate changes, more countries are becoming susceptible to PWD and, to prevent disease spread and limit economic and ec...
Characterization of the Skin Cultivable Microbiota Composition of the Frog Pelo...
Proença, Diogo Neves; Fasola, Emanuele; Lopes, Isabel; Morais, Paula V.Microorganisms that live in association with amphibian skin can play important roles in protecting their host. Within the scenarios of global change, it is important to understand how environmental disturbances, namely, metal pollution, can affect this microbiota. The aim of this study is to recognize core bacteria in the skin cultivable microbiota of the Perez frog (Pelophylax perezi) that are preserved regard...
Genome Sequences of Serratia Strains Revealed Common Genes in Both Serratomolid...
Marques-Pereira, Catarina; Proença, Diogo Neves; Morais, Paula V.Serratia strains are ubiquitous microorganisms with the ability to produce serratomolides, such as serrawettins. These extracellular lipopeptides are described as biocides against many bacteria and fungi and may have a nematicidal activity against phytopathogenic nematodes. Serrawettins W1 and W2 from different strains have different structures that might be correlated with distinct genomic organizations. This ...
Bacterial Metabolites Produced Under Iron Limitation Kill Pinewood Nematode and...
Proença, Diogo Neves; Heine, Thomas; Senges, Christoph H R; Bandow, Julia E; Morais, Paula V; Tischler, DirkPine Wilt Disease (PWD) is caused by Bursaphelenchus xylophilus, the pinewood nematode, and affects several species of pine trees worldwide. The ecosystem of the Pinus pinaster trees was investigated as a source of bacteria producing metabolites affecting this ecosystem: P. pinaster trees as target-plant, nematode as disease effector and its insect-vector as shuttle. For example, metals and metal-carrying compo...
The Microbiome of Endophytic, Wood Colonizing Bacteria from Pine Trees as Affec...
Proença, Diogo Neves; Francisco, Romeu; Kublik, Susanne; Schöler, Anne; Vestergaard, Gisle; Schloter, Michael; Morais, Paula V.Pine wilt disease (PWD) is a devastating forest disease present worldwide. In this study we analyzed the effects of the invasion of the pinewood nematode Bursaphelenchus xylophilus, the major pathogen causing PWD, on the endophytic microbiome of adult P. pinaster trees. Wood samples from trees with different degrees of PWD disease were collected at two sites (A and M) in Portugal. Endophytic bacteria were chara...
Diversity of Bacteria Carried by Pinewood Nematode in USA and Phylogenetic Comp...
Proença, Diogo Neves; Fonseca, Luís; Powers, Thomas O.; Abrantes, Isabel M. O.; Morais, Paula V.Pine wilt disease (PWD) is native to North America and has spread to Asia and Europe. Lately, mutualistic relationship has been suggested between the pinewood nematode (PWN), Bursaphelenchus xylophilus the causal nematode agent of PWD, and bacteria. In countries where PWN occurs, nematodes from diseased trees were reported to carry bacteria from several genera. However no data exists for the United States. The ...
