Harnessing the quest for eco-friendly alternatives to chemical surfactants by e...
Santos-Pereira, Cátia; Gomes, Joana; Sousa, Joana; Simões, Marta Filipa; Franco-Duarte, Ricardo; Silvério, Sara Isabel Cruz; Antunes, A.Surfactants are tensioactive chemical compounds extensively used worldwide in a myriad of industrial sectors, being an essential part of our everyday lives. They are present in numerous products including cosmetics, detergents, fabric softeners, toothpaste, paints, among many others, and millions of tonnes of surfactants are manufactured every year. Most commercially available surfactants are non-renewable petr...
Chapter 4 - Metagenomics to unravel the microbial biodiversity and biotechnolog...
Santos-Pereira, Cátia; Sousa, Joana; Silvério, Sara Isabel Cruz; Simões, Marta Filipa; Antunes, A.; Rodrigues, L. R."1st Edition - November 9, 2023" ; "Copyright 2024" ; Series: Developments in Applied Microbiology and Biotechnology; The concept of Microbial Dark Matter (MDM) refers to the wide biodiversity of yet-uncultivated microorganisms that can only be identified and studied by resorting to culture-independent techniques. These uncultured microbes are estimated to be dominant in all environments on Earth. The developme...
Mycogenic metal nanoparticles for the treatment of mycobacterioses
Simões, Marta Filipa; Ottoni, Cristiane Angélica [UNESP]; Antunes, AndréMade available in DSpace on 2020-12-12T01:37:43Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-09-01; Mycobacterial infections are a resurgent and increasingly relevant problem. Within these, tuberculosis (TB) is particularly worrying as it is one of the top ten causes of death in the world and is the infectious disease that causes the highest number of deaths. A further concern is the on-going emergenc...
Microbial fuel cell-induced production of fungal laccase to degrade the anthraq...
Simões, Marta Filipa; Maiorano, Alfredo Eduardo; dos Santos, Jonas Gomes; Peixoto, Luciana; de Souza, Rodrigo Fernando Brambilla; Neto, Almir OliveiraMade available in DSpace on 2019-10-06T15:39:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2019-09-01; The anthraquinone dye Remazol Brilliant Blue R is largely used in the textile industry. However, its removal from wastewaters is costly and complex. Many methods have been tested to solve this ecological problem, but there is still a need for efficient methods. We propose here an alternative use of a tw...
Polyphasic, including MALDI-TOF MS, evaluation of freeze-drying long-term prese...
Rodriguez, R.; Santos, Carla; Simões, Marta Filipa; Soares, Célia; Santos, Cledir; Lima, NelsonThis study aims to evaluate the effect of freeze-drying and long-term storage on the biotechnological potential of Aspergillus section Nigri strains. Twelve selected strains were freeze-dried and aged by accelerated storage, at 37 °C in the dark, for 2 and 4 weeks. To assess possible changes as a consequence of the ageing in the freeze-drying ampoules, morphological characteristics, mycotoxins and enzymes produ...
Application of microbial fuel cell technology for vinasse treatment and bioelec...
Ottoni, C.; Simões, Marta Filipa; Santos, Jonas G.; Peixoto, L.; Martins, Cleiton R.; Silva, Bruno P.; Neto, Almir O.; Brito, António José GuerreiroOur study evaluated the performance of different two-chambered microbial fuel cell (MFC) prototypes, operated with variable distance between electrodes and Nafion membrane and specific inoculum concentration, applied for vinasse treatment.; Instituto de Pesquisa Tecnológica do Estado de São Paulo/Programa Novos Talentos, through individual Research Grant attributed to Cristiane Angélica Ottoni.; info:eu-repo/se...
Screening of filamentous fungi for antimicrobial silver nanoparticles synthesis
Ottoni, Cristiane Angélica [UNESP]; Simões, Marta Filipa; Fernandes, Sara; dos Santos, Jonas Gomes; da Silva, Elda SabinoMade available in DSpace on 2018-12-11T16:45:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-12-01; The present work had the goal of screening a batch of 20 fungal strains, isolated from sugar cane plantation soil, in order to identify those capable of biosynthesis of silver nanoparticles. These nanoparticles are known to have a large and effective application in clinical microbiology. Four strains we...
Biotratamento de vinhaça sintética e geração de eletricidade utilizando uma cél...
Ottoni, C.; Simões, Marta Filipa; Santos, Joanas Gomes dos; Peixoto, L.; Souza, Rodrigo F. B.; Neto, Almir O.; Brito, António José GuerreiroAvanços Científicos e Tecnológicos em Bioprocessos; O Brasil é um dos maiores produtores de etanol no mundo, no entanto, durante o processo de obtenção deste combustível, elevadas quantidades de vinhaça são geradas, em média, para cada litro de etanol produzido são gerados 13 litros deste resíduo. A vinhaça possui propriedades físicas e químicas que podem desencadear efeitos nocivos à biota, deste modo, existe ...
Establishment of a quality management system based on ISO 9001 standard in a pu...
Simões, Marta Filipa; Dias, Nicolina; Santos, Cledir; Lima, NelsonCollaborations between different Microbiological Resource Centres (mBRCs) and ethical sourcing practices are mandatory to guarantee biodiversity conservation, successful and sustainable preservation and fair share of benefits that arise from the use of genetic resources. Since microbial Culture Collections (CCs) are now engaged in meeting high quality operational standards, they are facing the challenge of esta...
High laccase expression by Trametes versicolor in a simulated textile effluent ...
Ottoni, C. A.; Simões, Marta Filipa; Fernandes, S.; Santos, Cledir; Lima, NelsonTextile effluents are highly polluting and have variable and complex compositions. They can be extremely complex, with high salt concentrations and alkaline pHs. A fixed-bed bioreactor was used in the present study to simulate a textile effluent treatment, where the white-rot fungus, Trametes versicolor, efficiently decolourised the azo dye Reactive Black 5 over 28 days. This occurred under high alkaline condit...
