Xylose recovery from dilute-acid hydrolysis of oil palm (Elaeis guineensis) empty fruit bunches for xylitol production
The aim of this study was to evaluate the effect of different process conditions, such as the sulfuric acid concentration, contact time, solid:liquid ratio and particle size, on the xylose recovery
Bioethanol production by fermentation of hemicellulosic hydrolysates of african palm residues using an adapted strain of Scheffersomyces stipitis
Yeast adaptation showed to be and good strategy to produce ethanol from hemicellulosic residues of african palm tree, avoiding the detoxification processes.
Protonema suspension cultures of the medicinal moss Polytrichum juniperinum
This high cell density culture of P. juniperinum is suitable for further studies aimed at exploring and establishing a production platform for high-value secondary metabolites, which has scarcely been studied in this type of biological system.
Multi-objective optimization in biotechnological processes: application to plant cell suspension cultures of Thevetia peruviana
Bioprocesses productivity is a compromise between two conflicting objectives, maximization of biomass growth rate and minimization of substrate consumption. In this work, a model based
Protonema Suspension Cultures of Polytrichum Juniperinum as a Potential Production Platform for Bioactive Compounds
Ethyl acetate extract from field-collected moss and dichloromethane extract from protonema suspension cultures showed the greatest cell damage, and exhibited a dose-dependent cytotoxic effect against CHO-K1 cells.
Expresión de la proteína recombinante Cry 1Ac en cultivos de células de papa en suspensión: Establecimiento del cultivo y optimización de la producción de la biomasa y la proteína mediante la adición
A protocol for the establishment of potato suspensions genetically modified with Cry 1Ac gene was obtained and the kinetics of biomass and recombinant protein production were characterized, showing the best response in terms of callus formation.
Use of the cotton husk for the production of a Basidiomycete fungus in submerged culture
Basidiomycete fungi, also called white rot fungi, are known for their ability to degrade residues rich in complex compounds such as lignin and cellulose, since they have the enzymatic machinery to metabolize them and obtain their source of carbon and energy.
