Production and characterization of activated carbon from pineapple stubble for removal of methylene blue and surfactants

Autor: Johanna Méndez Arias, Natalia Montero Rambla, Diego Montenegro Quesada, Rodolfo Antonio Hernández Chaverri

Publikováno v: Journal of Applied Research and Technology. 19:521-539

The objective of this work was to produce activated carbon from the agricultural waste known as pineapple stubble, and to test its effectiveness in the removal of methylene blue and surfactants. Activated carbon was prepared using ZnCl2 and H3PO4 as

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
