The forest sector plays an important role in the circular bioeconomy due to its focus on renewable materials that can substitute fossil or greenhouse gas emissions-intensive materials, store carbon in bio-based products and provide ecosystem services. This study investigates the state of the bioeconomy in Brazil and its forest industry. Specifically, this study presents some examples of novel wood-based products being developed or manufactured in Brazil and discusses possible opportunities for the development of the country’s forest sector. The pulp and paper industry plays an important role in the forest sector. It has also been showing advancements in the development of cascading uses of wood invalue-added products, such as nanocrystalline cellulose, wood-based textile fibers, lignin-based products, and chemical derivatives from tall oil. Product and business diversification through the integration of the pulp and paper industry to biorefineries could provide new opportunities. Moreover, biochemicals derived from non-wood forest products, such as resin and tannins could promote diversification and competitiveness of the Brazilian forest industry. Although some engineered wood products are still a novelty in Brazil, the market for such products will likely expand in the future following the global trends in wood construction.
Considerando-se que a atual tendência do melhoramento florestal é a integração das técnicas clássicas com as de análise genética molecular, faz-se necessária a obtenção de protocolos de extração de DNA genômico ajustados a cada espécie estudada. O objetivo do trabalho foi determinar o efeito de diferentes adaptações no protocolo de extração de DNA genômico CTAB para acácia-negra. Foram testados diferentes componentes na fase de extração orgânica: clorofórmio, fenol e proteinase K, além da aplicação de RNase após a fase de precipitação e limpeza do DNA. Também, foi investigada a eficiência destes tratamentos em amostras de folíolos frescas ou armazenadas em baixa temperatura durante sete dias. Foi verificada a presença de DNA de todas as amostras submetidas à extração pelo protocolo de CTAB com os diferentes tratamentos. O tempo de armazenamento das amostras não influenciou na integridade do DNA, entretanto, foi possível observar que a adição de RNase melhorou a qualidade do DNA extraído. Deste modo, sugere-se a utilização do protocolo CTAB com uso de clorofórmio e RNase, com amostras frescas ou armazenadas em baixas temperaturas.
