The Speak Up For Blue Podcast

In this episode of the "How to Protect the Ocean" podcast, host Andrew Lewin discusses the pressing issue of plastic pollution and highlights a promising biological solution involving African mealworms. The episode focuses on the Kenyan lesser mealworm, a larval form of the Alphitobius darkling beetle, which has shown the ability to break down polystyrene, commonly known as styrofoam. This capability is attributed to the unique microbes and bacteria in the mealworms' gut. Researchers are studying these gut bacteria to identify specific communities that facilitate the degradation of plastic materials. Key findings from the research indicate that the mealworms can effectively digest polystyrene when provided with a nutrient-rich diet, such as bran, alongside the styrofoam. This balanced diet appears to enhance the production of the necessary bacteria and enzymes to break down plastic. The study revealed significant shifts in bacterial composition based on the mealworms' diet, suggesting that the gut microbiome
