Carbon sequestration associated to the land-use and land-cover changes in the forestry sector in Southern Brazil
(Spie-int Soc Optical Engineering, 2016-01-01)
We studied the Paraiba do Sul river watershed, Sao Paulo state (PSWSP), Southeastern Brazil, in order to assess the land use and cover (LULC) and their implications to the amount of carbon (C) stored in the forest cover ...
Short-term impacts of high levels of nitrogen fertilization on soil carbon dynamics in a tropical pasture
(2019-03-01)
Bermudagrass (Cynodon spp.) is widely recognized by its ability to respond positively to nitrogen (N) fertilization. Nitrogen often promotes shoot and root growth and, consequently, increase carbon (C) inputs into the soil ...
Sustainability of sugarcane production in Brazil. A review
(2018-04-01)
Brazil is a major sugarcane producer and its production more than doubled over the last decades to meet global bioenergy demands for reducing crude oil dependency and mitigating climate change. Nevertheless, the adverse ...
Engineering increased thermostability in the GH-10 endo-1, 4-β-xylanase from Thermoascus aurantiacus CBMAI 756
(2016-12-01)
The GH10 endo-xylanase from Thermoascus aurantiacus CBMAI 756 (XynA) is industrially attractive due to its considerable thermostability and high specific activity. Considering the possibility of a further improvement in ...
Sustainable intensification of sugarcane production under irrigation systems, considering climate interactions and agricultural efficiency
(2018-12-10)
Irrigation has been mentioned as one of the main strategies to increase sugarcane yield, but the challenge is how to make this opportunity in an environmentally compatible manner. The aim of this work is to assess the ...
Soil CO2 emission and short-term soil pore class distribution after tillage operations
(2019-03-01)
Alongside the agricultural development in Brazil, concerns have arisen about its environmental impacts, such as the emissions of CO2 resulting from soil cultivation and management practices in agricultural production ...
Plasma in-Liquid Using Non-contact Electrodes: A Method of Pretreatment to Enhance the Enzymatic Hydrolysis of Biomass
(2020-09-01)
Abstract: Dielectric Barrier Discharge (DBD) can be used to produce a large volume of non-thermal plasma at atmospheric pressure. Such plasmas are sources of highly reactive species (radicals, ozone, atoms, ions and excited ...
