Overview of Ecology and Aspects of Antibiotic Resistance in spp. Isolated from Free-Grazing Chicken Tissues in Rural Households.

Rural households all over the world rear backyard chicken mainly for their own consumption and, to a lesser extent, for barter trade. These chickens represent a staple dish with numerous culinary variations and a cheap source of protein. Although some species, and particularly and , have been associated with industrial poultry carcasses, studies concerning the ecology of this genus in rural households do not exist.

Wine production using free and immobilized kefir culture on natural supports.

The aim of the present study was to perform simultaneous alcoholic and malolactic wine fermentations using free or immobilized kefir culture at a wide temperature range (5-45 °C). Repeated batch fermentations were carried out for a period up to 29 months, suggesting a high operational stability of the systems, while malic acid conversion and ethanol productivity up to 70.9% and 36.
