The reliable supply of electricity plays a key role in the contemporary way of life. In order to provide more benefits to the population, electric networks are getting bigger to produce more energy. This growth, while necessary, brings problems in operation and maintenance, since the networks are more complex. This complexity requires that network security analysis should be performed in real time to avoid decision errors when disconnecting a device from the network or predicting the possibility ...

Pennisetum purpureum (elephant grass) is a tropical species presenting C4 metabolism and high productivity, yielding approximately 45 t of dry matter/ha/year. Such productivity makes elephant grass an interesting biomass source to produce second-generation ethanol. However, the high cost of enzymes for enzymatic hydrolysis is one bottleneck on the way to making the production of this biofuel economically viable. The production of cellulases and xylanases by Penicillium echinulatum 9A02S1 was evaluated ...

Elephantgrass has been a notable option as bioenergy plant. However, for its bioenergetic use, the quantification of genetic diversity based on biomass quality traits has not been commonly reported in the literature. The objective of this study was to quantify the genetic diversity among 100 accessions of the Active Elephantgrass Germplasm Bank (BAGCE), by means of morphological (flowering, height, vigor and stalk diameter), agronomic (total dry biomass) and biomass quality traits (dry matter concentration, ...

Pasture is the main food source for more than 200 million cattle heads in Brazil. Although Brazilian forage breeding programs have successfully released well-adapted, high-yielding cultivars over the years, the use of genomic tools in these programs is currently limited. These tools are required to tackle the main challenges for tropical forage breeding in Brazil. In this context, this notes lists the main research priorities raised at the workshop "Breeding Forages in the Genomic Era", which are ...
