In vitro antimicrobial activity of volatile compounds from the Lichen Pseudever...
Essadki, Yasser; Hilmi, Adel; Cascajosa-Lira, Antonio; Girão, Mariana; Darrag, El Mehdi; Rosário Martins, Maria; Romane, AbderrahmaneLichens are symbiotic organisms with unique secondary metabolism. Various metabolites from lichens have shown antimicrobial activity. Nevertheless, very few studies have investigated the antimicrobial potential of the volatile compounds they produce. This study investigates the chemical composition and antimicrobial properties of volatile compounds from Pseudevernia furfuracea collected in two regions of Morocc...
Unveiling the culturable and non‐culturable actinobacterial diversity in two ma...
Girão, Mariana; Alexandrino, Diogo A. M.; Cao, Weiwei; Costa, Isabel; Jia, Zhongjun; Carvalho, Maria F.; Alexandrino, DiogoActinomycetota, associated with macroalgae, remains one of the least explored marine niches. The secondary metabolism of Actinomycetota, the primary microbial source of compounds relevant to biotechnology, continues to drive research into the distribution, dynamics, and metabolome of these microorganisms. In this study, we employed a combination of traditional cultivation and metagenomic analysis to investigate...
Actinobacteria as new probiotics for preventing fish diseases in aquaculture
Santos, Matilde; Girão, Mariana; Oliveira, Rui S.; Carvalho, FátimaIn order to meet the food needs of a constantly growing world population, aquaculture emerges as the fastest growing food production sector. However, disease outbreaks due to opportunistic bacterial pathogens cause large losses. Antibacterial chemicals used indiscriminately have resulted in resistant bacteria and antibiotic resistance genes. Ecological solutions such as probiotics are needed. Probiotics are mic...
Resistance of actinobacteria and rhizobia from wild Saharan plants to environme...
Pereira, Adriana; Girão, Mariana; Fecih, Thinhinane; Carvalho, Fátima; Oliveira, Rui S.Plant growth promoting bacteria (PGPB) enhance plant development through various mechanisms such as the fixation of atmospheric nitrogen, production of siderophores and phosphate solubilization. This could be beneficial for the implementation of more sustainable agricultural practices. The objective of this study was to evaluate the effect of temperature and salinity variation as well as to evaluate the phospha...
Exposição ocupacional a fungos: um estudo de caso na indústria transformadora d...
Rocha, Ricardo; Neves, Maria Paula; Girão, Mariana; Carvalho, M. Fátima; Oliveira, Rui S.; Santos, JoanaOccupational exposure to fungi in the cork industry is responsible for several respiratory problems and can be influenced by factors such as automation level of the production process, type of ventilation, storage conditions and cooking times of cork boards. Thus, the main objective of this study was to evaluated and identified fungal species existing in the air and surfaces of slicing and punching workplaces i...
