Reuse of anaerobic reactor effluent on the treatment of poultry litter

Anaerobic digestion of poultry litter was studied with reutilization of its effluent in the process by pumping into reactor feeding, contributing to the moisture content and making part of the feeding organic load: 0.5 and 1.0 kg VS/m3/day, at evaluations 1 and 2, respectively. The hydraulic residence time lasted 10 days for both evaluations and the useful volume of reactor was 35 m3, with a semi-continuous reactor...

Survival of Salmonella Enteritidis and Escherichia coli in cactus cladodes under domestic marketing conditions in Mexico

In Mexico, during domestic marketing of cactus cladodes, called “nopalitos”, there is a tendency not to provide refrigerated storage, and sometimes dealers do not take care of the hygienic conditions of the product during commercialization. Therefore, the objective of this study was to evaluate the survival of Salmonella Enteritidis and Escherichia coli on cladodes of Opuntia ficus-indica Var. Atlixco under...

Effect of compaction of soil on the development and production of cowpea inoculated with rhizobium

Cowpea is considered as one of the most important species in Brazil, for presenting essential components to the feeding process, which makes it relevant to identify the physical, chemical and biological conditions that benefit or cause damage to its development. Thus, the objective of this study was to evaluate the effect of inoculation with rhizobia strains in compacted soil on the development and production of cowpea....
