Macaúba (Acrocomia aculeata) pulp oil ethylic biodiesel using lipase from Aspergillus oryzae: kinetic and process parameters

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Macaúba (Acrocomia aculeata), a native species from Brazilian biomes, has emerged as a sustainable alternative to vegetable oil production. Its fruit presents high oil yield (3–6 ton/ha), extracted from its kernel and pulp. While the kernel is suitable for food and cosmetics application, the pulp oil has been considered as a promising ...
