Nanobubble-enhanced oxygen transfer in bacterial nanocellulose production: Comp...
Rodrigues, Ana Cristina; Martins, Daniela; Carvalho, Ricardo; Marques, Susana; Belo, Isabel; Espina, Begona; Dourado, Fernando; Gama, MiguelABSTRACT: Despite the unique properties of bacterial nanocellulose (BNC), oxygen limitation during large-scale production impairs microbial metabolism and cellulose synthesis, leading to high production costs and limited commercial success. Static fermentation can achieve high titers, but industrially it is operationally challenging. Agitated systems like airlift (AL) bioreactors, allow faster production but ty...
Sustainable Production of Poly(3-hydroxybutyrate) Using Eucalyptus Bark: Integr...
Matias, João; Rodrigues, Thomas; Torres, Cristiana A. V.; Marques, Susana; Ribeiro, Belina; Gírio, Francisco; Reis, Maria A.; Freitas, FilomenaABSTRACT: This study integrates the valorization of a lignocellulose material into poly(3-hydroxybutyrate), P(3HB), with biopolymer extraction from bacterial cells with the enzyme alcalase. The work focused on Burkholderia thailandensis DSM 13276 as the P(3HB) producer and on eucalyptus bark, a byproduct from the pulp industry, as the sole feedstock for bacterial cultivation. The eucalyptus bark was hydrolyzed ...

Optimizing bacterial nanocellulose production from eucalyptus bark: a circular ...
Rodrigues, Ana Cristina Costa; Martins, Daniela Sofia Rodrigues; Duarte, Maria Salomé Lira; Carvalho, Ricardo Emanuel Silva; Marques, SusanaThe production cost of bacterial nanocellulose (BNC) is a major limitation to its widespread use. However, this limitation can be addressed by using alternative low-cost substrates and high-yield strains. Agro-industrial waste-derived substrates offer a cost-effective and sustainable solution, but their high organic load often requires additional downstream wastewater treatments. Here, we optimized static BNC p...
Biopolymers Derived from Forest Biomass for the Sustainable Textile Industry
Dias, J. C.; Marques, Susana; Branco, Pedro C.; Rodrigues, Thomas; Torres, Cristiana A.V.; Freitas, Filomena; Evtuguin, Dmitry; Silva, CarlaABSTRACT: In line with environmental awareness movements and social concerns, the textile industry is prioritizing sustainability in its strategic planning, product decisions, and brand initiatives. The use of non-biodegradable materials, obtained from non-renewable sources, contributes heavily to environmental pollution throughout the textile production chain. As sustainable alternatives, considerable efforts ...

Production of sustainable aviation fuel precursors using the oleaginous yeast R...
Saraiva Lopes da Silva, Maria Teresa; Dutra, Francisca; Gomes, Miguel; Costa, Paula; Paradela, Filipe; Ferreira, Frederico CasteloABSTRACT: Sustainable aviation fuels (SAF) obtained from renewable sources of carbon can reduce carbon dioxide emissions and contribute for mitigating climate changes. In the present study, the yeast Rhodotorula toruloides PYCC 5615 was found to be highly promising for the bioconversion of eucalyptus bark hydrolysate and the accumulation of intracellular lipids which were further thermochemically processed to b...
Alternative feedstocks for high-quality biodiesel: Lipid production from eucaly...
Dias, Bruna; Lopes, Marlene; Marques, Susana; Gírio, Francisco; Belo, IsabelABSTRACT: Microbial lipids produced by yeasts from lignocellulosic biomass are a promising feedstock for the biodiesel industry, providing a renewable energy source as an alternative to traditional fossil fuels. This study investigated the potential of Yarrowia lipolytica W29 to produce lipid-rich biomass from undetoxified sugar-concentrated eucalyptus bark hydrolysate (EBH). The lipid concentrations achieved i...
