Lactobacillus sakei MI806, Pediococcus pentosaceus MI810 and Pediococcus acidilactici MI807, able to produce bacteriocin-like inhibitory substances, were originally isolated from Lithuanian spontaneous rye sourdough and adapted in the novel fermentation medium containing extruded wheat material. The novel fermented products (50 and 65 % moisture content) were stored at the temperatures used in ...

BACKGROUND Pesticide use is widespread in agriculture. Several studies have shown that pesticides used in agricultural fields can contaminate the domestic environment and thus be an important source of pesticide exposure of populations residing nearby. Epidemiological studies that have examined the health effects of in utero pesticide exposure from residence near agricultural activities suggest...
