Monitoring Yeast Cultures Grown on Corn Stover Hydrolysate for Lipid Production
Fontes, Afonso; Francisco, Ricardo; Ferreira, Frederico Castelo; Faria, Nuno Torres; Marques, Susana; Reis, Alberto; Moura, Patrícia; Lukasik, Rafal M.ABSTRACT: Microbial oils can be used as an alternative sustainable and renewable feedstock to fossil reserves for producing lubricants and polyurethane materials. Two oleaginous yeasts were grown on non-detoxified corn stover hydrolysate supplemented with corn steep liquor and mineral medium in shake flasks. Trichosporon oleaginosus DSM 11815 displayed the highest lipid production. This strain was further culti...
Chemical composition and structural features of cellolignin from steam explosio...
Magina, Sandra; Marques, Susana; Gírio, Francisco; Lourenço, Ana; Barros-Timmons, Ana; Evtuguin, Dmitry V.ABSTRACT: Bark is one of the main wastes of the chemical and mechanical processing of Eucalyptus globulus wood. The proposed biochemical processing of bark via saccharification pathway involves steam explosion (SE) pretreatment (severity factor log R0 of 4.22) followed by enzymatic hydrolysis using an enzymatic cocktail composed of cellulolytic and xylanolytic enzymes. Almost 70% cellulose saccharification was ...
Biomass and microbial lipids production by Yarrowia lipolytica W29 from eucalyp...
Dias, Bruna; Lopes, Marlene; Fernandes, Helena; Marques, Susana; Gírio, Francisco; Belo, IsabelUsing lignocellulosic biomass hydrolysate as a renewable and abundant feedstock for microbial lipids production is a sustainable and economic high-potential approach. This study investigated the potential of the oleaginous yeast Yarrowia lipolytica to produce lipids-rich biomass from eucalyptus bark hydrolysate (EBH) obtained by enzymatic hydrolysis of the biomass pretreated by steam explosion. The effect of EB...
Single-Cell Oil Production by Engineered Ashbya gossypii from Non-Detoxified Li...
Francisco, Miguel; Aguiar, Tatiana Q.; Abreu, Gabriel; Marques, Susana; Gírio, Francisco; Domingues, LucíliaABSTRACT: In this work, microbial lipid production from non-detoxified Eucalyptus bark hydrolysate (EBH) with oleaginous xylose-utilizing Ashbya gossypii strains was explored. The best producing strain from a set of engineered strains was identified in synthetic media mimicking the composition of the non-detoxified EBH (SM), the lipid profile was characterized, and yeast extract and corn steep liquor (CSL) were...
Admissibility Grid to Support the Decision for the Preferential Routing of Port...
Crujeira, Teresa; Trancoso, Maria Ascensão; Eusebio, Ana; Oliveira, Ana Cristina; Passarinho, Paula; Abreu, Mariana; Marques, Isabel PaulaABSTRACT: A methodology was developed to assess the allocation of different types of endogenous waste biomass to eight technologies for producing electricity, heat, biogas and advanced biofuels. It was based on the identification of key physicochemical parameters for each conversion process and the definition of limit values for each parameter, applied to two different matrices of waste biomass. This enabled th...
Síndrome Hemofagocítica Associada a Leishmaniose Visceral: Um Caso Clínico
Saraiva dos Santos, Francisca; Brigas, Daniela; Lopes Madeira, Margarida; de Barros Viegas, Hugo; Dias, Eugénio; Marques, SusanaA síndrome hemofagocítica é uma condição rara em que um estado hiperinflamatório grave pode resultar em falência multiorgânica e por em risco a vida. Pode ser genético ou adquirido na sequência de infeções, neoplasias malignas, doenças autoimunes ou imunodeficiências. Os autores descrevem o caso de um jovem de 19 anos de idade que recorreu ao Serviço de Urgência por um sinus pilonidalis sacrococcígeo infetado, ...

Editorial
Marques, Rui Pedro; Vieira, Elisabete; Azevedo, Graça; Marques, SusanaWith this issue, we begin the second volume of lnternational Journal of Business Innovation (IJBI). Also like this, we started another new stage of the journal. If the first volume is associated with the launch and promotion of the journal, this second volume is intended to be of consolidation. Consolidation and affirmation! In this volume, therefore, we intend to increase the number of submissions, thus reduci...
Editorial
Marques, Rui Pedro; Vieira, Elisabete; Azevedo, Graça; Marques, SusanaIt is with satisfaction that the editorial team of IJBI - International Journal of Business Innovation presents its second issue of the second volume. Despite several articles submitted from various scientific areas, this issue, by editorial decision, concentrates articles only from the scientific area of accounting, thus allowing to provide readers from this scientific area with a collection that brings togeth...
Kinetics of the Release Sugars from the Enzymatic and Physico-Chemical Pre-trea...
Codato-Zumpano, Carolina Brito; Gírio, Francisco; Carvalheiro, Florbela; Marques, Susana; Ceccato-Antonini, Sandra Regina; Bastos, ReinaldoABSTRACT: Several pre-treatments are used to release sugars from lignocellulosic materials that are used to produce second-generation ethanol (2G). This study aimed to evaluate the kinetic release of glucose and xylose through the enzymatic and physical treatments of sugarcane bagasse and residual forest biomass, focusing on the ratio between hexose and pentose. Enzymatic hydrolysis after hydrothermal pre-treat...
