Electrical potentials of protoscoleces of the cestode Echinococcus granulosus from bovine origin.

Larval stages of taeniid Echinococcus granulosus are the infective forms of cystic echinococcosis or hydatidosis, a worldwide zoonosis. The protoscolex that develops into the adult form in the definitive host is enveloped by a complex cellular syncytial tegument, where all metabolic interchange takes place. Little information is available as to the electrical activity of the parasite in this developmental stage.

Effect of the clarification pH of sorghum juice on the composition of essential nutrients for fermentation.

The growing demand to replace fossil fuels with renewable alternatives has generated an urgent and imminent global need to find new non-fossil sources. Sweet sorghum is widely recognized as a highly promising biomass energy crop with the particular potential to complement sugarcane for ethanol production. Our aim in this study was to evaluate the influence of pH during the clarification process on the composition of essential nutrients in the sorghum juice and observe how this affects the efficiency of the ethanol fermentation process.
