Evaluation of enzymatic pretreatment strategies to enhance anaerobic digestion of tomato waste

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tomato residues are a form of solid waste that can be converted into methane through anaerobic digestion (AD). However, methane production is often limited due to incomplete hydrolysis caused by the high lignocellulosic content of tomato waste.

Bioethanol production from fruit waste using a microbial co‐culture of Bacillus siamensis F2 and Candida albicans GP1

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study explores the sustainable valorization of fruit waste (FW) for bioethanol production using a consolidated bioprocess (CBP) that combines fermentation and enzymatic hydrolysis in a single step. A co‐culture of Bacillus siamensis F2 (a multienzyme producer) and Candida albicans GP1 (a fermentative yeast) was employed to maximize ...

Sequential fractionation and polyoxometalate‐catalyzed oxidation of lignocellulosic biomass improves cellulose purity and formic acid yield

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Lignocellulosic biomass is an important source of renewable chemicals and materials but its full valorization is necessary in order to achieve economic and sustainability goals. This study proposes a two‐step approach for the valorization of lignocellulosic biomass combining solvent‐assisted fractionation and catalytic oxidation with molecular

Sustainable biofuel production from fish processing waste: lipase‐catalyzed hydroesterification of tilapia residual oil

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fishing waste and byproducts, whether naturally occurring or from industrial processing, are important sources of high‐value compounds. Fertilizers, biomaterials, cosmetics, biolubricants, and biodiesel are some of the substances that can be obtained from these residues. The objective of this study was to conduct a theoretical and experimental
