Probiotic and strains possess safety characteristics, antiviral activities and host adherence factors revealed by genome mining.

Background: Probiotics belonging to and spp. have been exploited for their health benefits in treatment and prevention of many pathological conditions and promoting human health. Recent advances in understanding probiotics-human interaction through microbiome research in the context of various medical conditions suggest their provisional role in preventive, personalized, and predictive medicine.

Recombinant production of omega-3 fatty acids by probiotic Escherichia coli Nissle 1917.

Omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have beneficial effects on human health. The probiotic bacterium Escherichia coli Nissle is unable to produce either EPA or DHA. Escherichia coli Nissle was transformed with the pfBS-PS plasmid carrying the EPA/DHA gene cluster, previously isolated from a marine bacterium.
