Avaliação da recalcitrância da parede celular e desenvolvimento de diferentes espécies de bambu como fonte de biomassa para a produção bioenergética

Abstract

Now a days, there is great concern about fossil fuels because they have finite reserves, and their use is a major contributor to the polluting gases that are causing climate change and global warming. The replacement of fossil energy sources by renewable energy has been sought in order to diversify the energy supply around the world. Due to big extension in agricultural areas, Brazil stands out in the world scenario, with wide climatic diversity and exuberance of biodiversity. Produced from vegetal biomass, biofuels have been standing out in the energy sector as an alternative to fossil fuels. Bamboo presents high potential for the production of biofuels, being characterized as a natural resource and of rapid renewal. One of the greatest virtues of this grass is to have a woody tissue on its physiological structure, also making it possible to use it in the construction area with excellence. Therefore, in the present study reviews the development of some species of bamboo, as well as the lignin, ferulic acid and cumaric acid contents and the cell wall digestibility for the bioenergetic production. The results indicated that the bamboo species Phyllostachys edulis, Guadua Chacoienses and Bambusa vulgaris would have greater potential for the production of biofuels, however, Phyllostachys edulis did not adapt to the soil and climatic conditions of region, so, the species Guadua chacoienses and Bambusa vulgaris are the most indicated for the production of biofuels through laboratory analyses and adapted to maringaense region.
