Probiotic microorganisms have attracted a growing interest for prevention and therapy of gastrointestinal disorders. Many probiotic strains have been shown to inhibit growth and metabolic activity of enteropathogenic bacteria as well as their adhesion and invasion to intestinal cells. In the present study, we evaluated the interference of bacteria-free supernatants (BFS) of cultures belonging t...

Water ionization is an efficient physical water treatment technology, and crop nutrient use efficiencies can be improved using ionized for irrigation. In order to explore the effect of on soil nitrification nitrifying microorganisms, we conducted a laboratory incubation experiment with addition ordinary under different contents (equal 30%, 60%, 100% 175% field capacity, θFC). During incubation,...
