Cr-free Ni/MgO catalysts for hydrogenation of furfural [PDF]

open access: yes, 2018
In the last century, the industrial development and the increase of the world population have caused the depletion of fossil reserves. This fact together with others factors have led to the search of alternative.

Changes in volatile composition of Madeira wines during their oxidative ageing [PDF]

open access: yes, 2006
The influence of the age in the volatile composition of Madeira wines made with Boal, Malvazia, Sercial and Verdelho varieties and aged in oak barrel during 1, 11 and 25 years old was been studied.

Industrial strategies to minimize glycerol formation in ethanol fermentation by conventional Saccharomyces cerevisiae

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 1006-1020, March/April 2026.
Abstract Industrial ethanol production faces the challenge of balancing metabolic efficiency with the minimization of byproducts such as glycerol, whose formation is intensified by osmotic, thermal, oxidative, and nutritional stresses. In the literature, two main approaches stand out for modulating its synthesis: the use of genetically modified strains

Process development priorities for scaling up direct microbial conversion of sugars into value‐added biochemicals

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 747-765, March/April 2026.
Abstract The study identified process development priorities toward the feasible production of five value‐added biochemicals in a sugarcane biorefinery based on achievable bioconversion performances. Multiple process scenarios using A‐molasses as feedstock were simulated in Aspen Plus® via direct microbial conversions.

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 703-716, March/April 2026.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped

Integrated bioconversion of starchy and hemicellulosic fractions of macauba oil presscake into ethanol by nonconventional yeasts

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 779-792, March/April 2026.
Abstract Co‐fermentation of hexoses and pentoses from plant biomass to ethanol is a strategy to increase ethanol production from lignocellulosic materials and add value to residues from agroindustrial chains. The macauba (Acrocomia aculeata) is an oleaginous palm‐tree species considered to contribute to development in some regions of Brazil.

Market potential of biobased chemicals: a qualitative network analysis of adoption dynamics in South Africa’s bioeconomy

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 854-878, March/April 2026.
Abstract The premise of a bioeconomy is the replacement of nonrenewable and unsustainable fossil‐derived resources and associated technologies with more sustainable alternatives. The adoption of biobased chemicals contributes toward the growth of a bioeconomy and is dependent on market and industry requirements.
