Microcrystals and Microfibers of Cellulose from Acrocomia aculeata (Arecaceae) Characterization

ENVABIO100, 2023
In the context of the so-called lignocellulose bio-refinery, the coconut shell (S) and pulp (P) of Acrocomia aculeata (Arecaceae) are interesting agro-industrial wastes that can be used as feedstock for the production of high value-added products. The aim of this work was to evaluate these lignocellulosic residues S and P, to obtain the microcrystal ...

Acúmulo de sementes de Acrocomia aculeata (Arecaceae) na bochecha de búfalos no Pará Acumulation of the seeds of Acrocomia aculeata (Arecaceae) in the cheeks of buffaloes in the State of Pará, Brazil

Pesquisa Veterinária Brasileira, 2009
Foi demonstrado que uma condição em búfalos caracterizada pelo aumento de uma das bochechas é causada pelo acúmulo das sementes da palmeira "mucajá"(Acrocomia aculeata, fam. Arecaceae) e de capim no vestíbulo oral, durante a ruminação.

Legacy of Amazonian Dark Earth soils on forest structure and species composition

Global Ecology and Biogeography, Volume 29, Issue 9, Page 1458-1473, September 2020., 2020
Abstract Aim Amazonian forests predominantly grow on highly weathered and nutrient poor soils. Anthropogenically enriched Amazonian Dark Earths (ADE), traditionally known as Terra Preta de Índio, were formed by pre‐Columbian populations. ADE soils are characterized by increased fertility and have continued to be exploited following European ...

Population modelling and genetics of a critically endangered Madagascan palm Tahina spectabilis

Ecology and Evolution, Volume 10, Issue 6, Page 3120-3137, March 2020., 2020
Abstract Madagascar is home to 208 indigenous palm species, almost all of them endemic and >80% of which are endangered. We undertook complete population census and sampling for genetic analysis of a relatively recently discovered giant fan palm, the Critically Endangered Tahina spectablis in 2008 and 2016.

Macauba (Acrocomia aculeata): Biology, Oil Processing, and Technological Potential

, 2023
The global production of vegetable oil has increased since the beginning of the century, reaching a peak of 209 million tons in 2020/2021 and is projected to continue to increase due to population growth and the impact of the biodiesel industry. In this context, palm oil and soybean oil have stood out.

Evaluating the Microstructure and Interaction of Bioaggregates in Concrete Using microCT

X-Ray Spectrometry, Volume 55, Issue 2, Page 285-293, March/April 2026.
ABSTRACT This study investigates the use of x‐ray computed microtomography (microCT) to evaluate the incorporation of bioaggregates—specifically macauba (Acrocomia aculeata) endocarp and jute fibers—into cement‐based composites. MicroCT enables non‐destructive, three‐dimensional characterization of the internal microstructure, providing insights into ...
