Yarrowia lipolytica uses olive tree prunings hydrolysates for microbial lipids ...
Dias, Bruna Filipa Silva; Rodríguez-Jasso, Rosa M.; Belo, Isabel; Lopes, MarleneEfficiently valorizing olive tree prunings (OTP) for microbial lipids represents an excellent strategy to achieve resource circularity, accompanied by economic and environmental benefits. Since the production of lipids from OTP hydrolysate (OTPH) by yeasts remains underexplored, this study investigated the potential of Y. lipolytica to produce lipid-rich biomass in bioreactor batch cultures. OTP was fractionate...
Hydrothermal pretreatment and enzymatic hydrolysis of olive tree prunings for l...
Dias, Bruna; Rodríguez-Jasso, Rosa M.; Belo, Isabel; Lopes, MarleneIn recent years, the challenges of climate change, the energy crises, waste management issues, and accelerating resource exhaustion have driven research into a search for sustainable alternatives to fossil fuels. Lignocellulosic materials, owing to their widespread availability, minimal carbon footprint, and desirable composition, have garnered attention in the context of 2nd generation biorefineries for the pr...
Hydrothermal–microwave processing for starch extraction from mexican avocado se...
Araújo, Rafael G.; Rodríguez-Jasso, Rosa M.; Ruiz, Héctor A.; Govea-Salas, Mayela; Rosas-Flores, Walfred; Aguilar-González, Miguel AngelAvocado seeds are an agroindustrial residue widely produced in Mexico that are causing various environmental problems due to their accumulation. The evaluation of avocado residues to recover biopolymers by microwave-assisted extraction (MAE) and the characterization of avocado starch properties were studied in the present work. A central-composite design was used to optimize the MAE process. Moreover, a compari...
Engineering aspects of hydrothermal pretreatment: from batch to continuous oper...
Ruiz, Héctor A.; Conrad, Marc; Sun, Shao-Ni; Sanchez, Arturo; Rocha, George J. M.; Romani, Aloia Perez; Castro, Eulogio; Torres, AnaDifferent pretreatments strategies have been developed over the years mainly to enhance enzymatic cellulose degradation. In the new biorefinery era, a more holistic view on pretreatment is required to secure optimal use of the whole biomass. Hydrothermal pretreatment technology is regarded as very promising for lignocellulose biomass fractionation biorefinery and to be implemented at the industrial scale for bi...
Edible mushrooms as a novel protein source for functional foods
Gonzalez, Abigail; Cruz, Mario; Losoya, Carolina; Gonçalves, Clarisse Salomé Nobre; Loredo, Araceli; Rodríguez-Jasso, Rosa M.; Contreras, Juan CarlosFast demographic growth has led to an increasing interest in low-cost alternative protein sources to meet population needs. Consequently, the attention of many researchers has focused on finding under-exploited sources of protein, alternative to those of animal origin, usually plant proteins have been used for this purpose, however, most of them are not considered high quality proteins due to their lack of some...
Sustainable approach of high-pressure agave bagasse pretreatment for ethanol pr...
Aguirre-Fierro, Arelí; Ruiz, Héctor A.; Cerqueira, Miguel A.; Ramos-González, Rodolfo; Rodríguez-Jasso, Rosa M.; Marques, Susana; Lukasik, Rafal M.ABSTRACT: Agave bagasse is one of the most abundant lignocellulosic residues readily available for valorization. The agave bagasse was pretreated by applying high-pressure CO2–H2O mixture at temperatures ranging from 150 to 190 °C for a residence time varying from 10 to 50 min. Subsequently, solid phase obtained from pretreatment was subject to enzymatic hydrolysis at high solid loadings. Under optimal conditio...
Chapter 5: Biological catalyzers of brown seaweed: biochemical properties, prod...
Cabello-Galindo, Alejandra; Ruiz, Héctor A.; Nobre, Clarisse; Prado-Barragán, Lilia Arely; Rodríguez-Herrera, Raúl; Aguilar, Cristóbal N.Brown seaweeds comprise a unique and rich composition of relevant polysaccharides and bioactive compounds that can reach up to 70% of seaweed tissue, with a wide application in food, nutraceutical, pharmaceutical, cosmetic, and biopolymer industries; but due to the complexity of the seaweed cell wall structure, the extraction methods play a very important role in the recovery of significant amounts of hydrocoll...
Enhancement and modeling of enzymatic hydrolysis on cellulose from Agave bagass...
Pino, Marcela Sofía; Rodríguez-Jasso, Rosa M.; Michelin, Michele; Ruiz, Héctor A.One of the major challenges in biofuels production from lignocellulosic biomass is the generation of high glucose titers from cellulose in the enzymatic hydrolysis stage of pretreated biomass to guarantee a cost-effective process. Therefore, the enzymatic saccharification on cellulose at high solid loading is an alternative. In this work, the agave bagasse was hydrothermally pretreated and optimized at 194°C/30...
Scale-up and evaluation of hydrothermal pretreatment in isothermal and non-isot...
Aguilar, Daniela L.; Rodríguez-Jasso, Rosa M.; Zanuso, Elisa; Rodríguez, Diana Jasso de; Amaya-Delgado, Lorena; Sanchez, Arturo; Ruiz, Héctor A.The production of tequila in Mexico generates a large amount of agave bagasse per year. However, this biomass can be considered as a potential source for biofuel production. In this study, it is described how the hydrothermal pretreatment was scaled in a bench scale, considering the severity index as a strategy. The best condition was at 180°C in isothermal regime for 20min with 65.87% of cellulose content and ...
Microalgal biomass pretreatment for bioethanol production: a review
Velazquez-Lucio, Jesús; Rodríguez-Jasso, Rosa M.; Colla, Luciane M.; Sáenz-Galindo, Aide; Cervantes-Cisneros, Daniela E.; Aguilar, Cristóbal N.Biofuels derived from microalgae biomass have received a great deal of attention owing to their high potentials as sustainable alternatives to fossil fuels. Microalgae have a high capacity of CO2 fixation and depending on their growth conditions, they can accumulate different quantities of lipids, proteins, and carbohydrates. Microalgal biomass can, therefore, represent a rich source of fermentable sugars for t...
