The Landless Rural Workers Movement (MST) and New Agrarian Questions in Brazil

Journal of Agrarian Change, EarlyView.
ABSTRACT The Landless Rural Workers Movement of Brazil (MST) primarily organized occupations of large‐scale farms, forcing the redistribution of land for creation of agrarian reform settlements. In the past 20 years, however, land occupations and the establishment of new agrarian reform settlements have consistently declined, while the MST shifted ...

Analysis, Design and Implementation of Biodiesel Projects in Brazil [PDF]

During the oil crisis of the seventies, Brazil has developed a successful program for gasoline substitution by ethanol (Proálcool). Nowadays the biomass accounts for 27% of total national energy consumed in Brazil and the ethanol participates with 40% of

Multiplex FAD2/FATB Editing Generates Ultra‐High‐Oleic, Low‐Saturate Soybean With Increased Seed Fatty Acid Content

Plant Biotechnology Journal, EarlyView.
ABSTRACT Oleic acid (18:1), saturated fatty acid (SFA), and polyunsaturated fatty acid (PUFA) levels are important traits for storage stability and edibility. In this study, we aimed to develop high‐oleic soybean (Glycine max) by simultaneously targeting fatty acid desaturase 2 (FAD2) and fatty acyl‐ACP thioesterase B (FATB) gene families using CRISPR ...

Genome‐Wide Association Study Elucidates the Genetic Architecture of Manganese Tolerance in Brassica napus

Plant, Cell &Environment, EarlyView.
ABSTRACT Brassica napus (canola) is a significant contributor to the world's oil production and is cultivated across continents, yet acidic soils with aluminium (Al3+) and manganese (Mn2+) toxicities limit its production. The genetic determinants underlying natural variation for acidic soil tolerance in canola are unknown and need to be determined ...

Citric‐Acid Polyester‐Modified Melamine–Formaldehyde Resins: Mechanistic Insights and Implications for Greener Decorative Laminates

Journal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
Driven by the need for more sustainable materials in the laminate industry, poly(glycerol citrate) was introduced as a bio‐based modifier that significantly altered the cure kinetics and structural evolution of melamine–formaldehyde resins. Correlated FTIR, DSC, TGA, and rheological analyses revealed accelerated network formation, enabling lower ...

Resource Recovery From Food Processing Wastewater Through Microalgae‐Driven Carbon Chain Rearrangement

GCB Bioenergy, Volume 18, Issue 10, October 2026.
Carbon chain rearrangement reframes food‐processing wastewater treatment from COD removal to controlled carbon recovery. By coupling microalgal biosynthesis with bacterial substrate transformation, algal–bacterial consortia can redirect heterogeneous wastewater carbon toward recoverable biomolecules.

Ketal Protection of Glycerol for Selective Electrosynthesis of Glyceric Acid in Highly Alkaline Media

Angewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Using a ketal‐protected glycerol derivative (solketal) as the oxidation substrate enables site‐selective electrooxidation that suppresses C–C cleavage on non‐noble catalysts. Highly alkaline conditions promote reactive solketal alkoxide formation, weaken the Cα─H bond to facilitate dehydrogenation, and buffer local acidification, enabling a record‐high

Synergistic Action of Rhizopus oryzae Lipase and Fusarium oxysporum Cutinase in the Enzymatic Transesterification of a High‐Free Fatty Acid Oil

ChemBioChem, Volume 27, Issue 17, 14 September 2026.
A bienzymatic system of Rhizopus oryzae lipase and Fusarium oxysporum cutinase was optimized for the transesterification of high‐free fatty acid waste oil into biodiesel. Synergistic enzyme action, immobilization‐enabled reusability, and successful 100 mL scale‐up highlight the industrial potential of the suggested biocatalytic approach.
