ISEF 2019 Team Profile Eliza Martin – Don’t Cry over Undigested Milk

Eliza examined the potential use of probiotics and synbiotics for the long- term treatment of lactose intolerance by analysing their effectiveness in breaking down lactose in milk samples into glucose and galactose. She measured the concentration of glucose as well changes in pH before and after the addition of probiotics or synbiotics as an indicator of their success in breaking down lactose. The results suggested that probiotics are effective in removing lactose from milk and can do so faster than synbiotic formulations.
