Evaluación del uso de trampa de evaporación en la evaporación en la calibración de pipetas de pistón en volúmenes menores o iguales a 100 µL

Autor: Johanna Méndez Arias

Publikováno v: Ingeniería, Vol 27, Iss 2 (2017)

El presente documento tiene como objetivo demostrar la importancia de utilizar trampa de evaporación durante el proceso de calibración de pipetas de pistón, específicamente a niveles de microlitros (µL). Se realizaron calibraciones a una pipeta

Enzymatic conversion of treated oil palm empty fruit bunches fiber into fermentable sugars: optimization of solid and protein loadings and surfactant effects

Autor: Camila Charpentier Alfaro, Johanna Méndez Arias

Publikováno v: Biomass Conversion and Biorefinery. 11:2359-2368

Empty palm fruit bunches fiber (EPFBF) is a lignocellulosic biomass by-product of palm oil production. In the present work, EPFBF was pretreated with sequential diluted acid/alkali to enhance the material’s enzymatic digestibility. Response surface

Changes in the structure and composition of pineapple leaf fiber after alkali and ionic surfactant pretreatments and their impact on enzymatic hydrolysis

Autor: Débora Zúñiga-Arias, Camila Charpentier-Alfaro, Johanna Méndez-Arias, Karina Rodríguez-Mora

Publikováno v: Preparative biochemistrybiotechnology. 52(8)

The current study investigated the effects of two different pretreatments (NaOH and alkaline surfactant assisted) on the chemical, morphological and enzymatic saccharification of pineapple leaf fiber (PALF). Results showed that both pretreatments sig

Addition of Surfactants and Non-Hydrolytic Proteins and Their Influence on Enzymatic Hydrolysis of Pretreated Sugarcane Bagasse

Autor: Luiz Felipe Modesto, Nei Pereira, Anelize de Oliveira Moraes, Johanna Méndez Arias, Aline Machado de Castro

Publikováno v: Applied Biochemistry and Biotechnology. 181:593-603

Poly(ethylene glycol) (PEG 4000) and bovine serum albumin (BSA) were investigated with the purpose of evaluating their influence on enzymatic hydrolysis of sugarcane bagasse. Effects of these supplements were assayed for different enzymatic cocktails
