Biofilm formation by Salmonella sp. in the poultry industry: Detection, control and eradication strategies por Merino, Lina Ethel, Procura, Francisco, Trejo, Fernando Miguel, Bueno, Dante Javier, Golowczyc, Marina Alejandra

“…A number of methodologies based on different approximations have been recently employed to detect and evaluate bacteria attached to surfaces, including real-time polymerase chain reaction (PCR), confocal laser scanning microscopy and Optical Coherence Tomography. Due to persistence of Salmonella biofilm in food processing environments after cleaning and sanitation, control and eradication strategies in poultry industry should be constantly studied. …”

Eco-hydrological characterization of inland wetlands in Africa using L-Band SAR por Rebelo, Lisa-Maria

“…The L-band SAR datasets have proved to be an essential information source in the production of these maps due to i) frequent cloud cover/smoke which reduces the temporal coverage of optical data, and ii) a systematic observation strategy and frequent image acquisition which enables characterization of the flood dynamics at a high temporal resolution.…”
