Probiotics in the Food Industry

Probiotics are defined as live bacteria with beneficial effects to the health of the host organism. Pimarily lactic acid bacteria (LAB) and bifidobacteria are used as probiotics, however certain yeasts and bacilli are also known to have positive effects

Microbiological Media and Detection

Molecular biology-based methods, like PCR, can be used for lactobacilli detection.

Probiotics and Human Health

Today, diverse studies report the benefits of probiotics, such as inhibitory effects on pathogens, aid in the management or prevention of chronic intestinal inflammatory diseases or atopic syndromes, and support to the immune system. Potential beneficial applications abound, researchers continue to evaluate the effictiveness and clarify the mechanisms of action of probiotics.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
