Engineering lactococci to reduce human lactose intolerance; biotechnology and risk/benefit assessment toward the gut microbiota of lactose-intolerants

Key Points

• Gut microbiota modifications may help alleviate symptoms of lactose intolerance, improving quality of life.
• Lactococci effectively metabolize lactose, enhancing metabolism for lactose-intolerant individuals.
• This biotechnology approach highlights the potential for dietary interventions to support gut health.
• Risk assessment indicates a need for careful evaluation before widespread implementation of engineered probiotics.
