Antibacterial and antioxidant potential of aqueous extracts of bio-residues fro...
Sousa, A. S.; Marçal, S.; Costa, C.; Ferreira, I.; Barros, J.; Nunes, J.; Freitas, A. C.; Morais, A. M. M. B.; Pintado, M.The production of fresh mushrooms results in a large quantity of bio-residues, which may account for more than 20% of a crop volume and contributes to production costs and environmental impact, if not used. These products consist mainly of stalks, mushrooms of irregular dimensions and shape and basal material. Thus, the main objective of MicoBioExtract project is the valorisation of these bio-residues and the d...

Salinity induced effects on the growth rates and mycelia composition of basidio...
Venâncio, C.; Pereira, R.; Freitas, A. C.; Rocha-Santos, T. A. P.; Costa, J. P. da; Duarte, A. C.; Lopes, I.Soil salinization, as the combination of primary and secondary events, can adversely affect organisms inhabiting this compartment. In the present study, the effects of increased salinity were assessed in four species of terrestrial fungi: Lentinus sajor caju, Phanerochaete chrysosporium, Rhizopus oryzae and Trametes versicolor. The mycelial growth and biochemical composition of the four fungi were determined un...

Exploring OHS trainers’ role in the transfer of training
Freitas, A. C.; Silva, S. A.Safety training (ST) is essential for workplace safety and to be effective requires that the learned knowledge and skills are transferred to the job. Research on transfer mechanisms and its predictors has neglected trainers’ influence, despite their privileged position on decisions related with training. This study is aimed at identifying: (1) trainers’ perspectives on best practices for enhancing ST success; (...
Biological treatment with fungi of olive mill wastewater pre-treated by photoca...
Nogueira, V.; Lopes, I.; Freitas, A. C.; Rocha-Santos, T. A. P.; Gonçalves, F.; Duarte, A. C.; Pereira, R.Olive mill wastewater (OMW) still is a major environmental problem due to its high chemical oxygen demand (COD) and total phenolic content (TPC), contributing for the high toxicity and recalcitrant nature. Several attempts have been made for developing more efficient treatment processes, but no chemical or biological approaches were found to be totally effective, especially in terms of toxicity reduction. In th...
Removal of phenolic compounds in olive mill wastewater by silica-alginate-fungi...
Duarte, K. R.; Justino, C.; Panteleitchouk, T.; Zrineh, A.; Freitas, A. C.; Duarte, A. C.; Rocha-Santos, T. A. P.This study aims to attempt a treatment strategy based on fungi immobilized on silica-alginate (biocomposites) for removal of phenolic compounds in olive oil mill wastewater (OMW), OMW supplemented (OMWS) with phenolic compounds and water supplemented (WS) with phenolic compounds, thus decreasing its potential impact in the receiving waters. Active (alive) or inactive (death by sterilization) Pleurotus sajor caj...
Toxicity of organic and inorganic nanoparticles to four species of white-rot fungi
Galindo, T P S; Pereira, R.; Freitas, A. C.; Santos-Rocha, T. A. P.; Rasteiro, M. G.; Antunes, F.; Rodrigues, D.; Soares, A. M. V. M.; Gonçalves, F.The rapid development of nanoparticles (NP) for industrial applications and large-volume manufacturing, with its subsequent release into the environment, raised the need to understand and characterize the potential effects of NP to biota. Accordingly, this work aimed to assess sublethal effects of five NP to the white-rot fungi species Trametes versicolor, Lentinus sajor caju, Pleurotus ostreatus, and Phaneroch...
Development of probiotic tablets using microparticles: viability studies and st...
Sousa e Silva, J. P.; Sousa, Sérgio C.; Costa, Paulo; Cerdeira, Emília; Amaral, Maria H.; Lobo, José Sousa; Gomes, Ana M. P.; Pintado, Maria M.Alternative vectors to deliver viable cells of probiotics, to those conferring limited resistance to gastrointestinal conditions, still need to be sought. Therefore the main goal of the study was to develop tablets able to protect entrapped probiotic bacteria from gastric acidity, thus providing an easily manufacturing scale-up dosage form to deliver probiotics to the vicinity of the human colon. Whey protein c...
