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

Biofuels, 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.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna

Biological Reviews, Volume 101, Issue 1, Page 74-105, February 2026.
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...
