Professor Marco’s team is investigating the ecology and molecular genetics of beneficial bacteria associated with plant surfaces and mammalian digestive tracts. Organisms of particular interest in the Marco lab are Lactic Acid Bacteria (LAB) found in plant and gut environments. LAB are important for the production of (fermented) food products and specific strains are currently being applied as probiotics to deliver health benefits in the human gut. This lab aims to understand the molecular adaptations and activities of LAB in the context of the indigenous plant and gut microbiota to improve food production and maintain human health.
