    Sharing the Story of Agar and Fanny Angelina Hesse: Dr. Corrado Nai

    Agar is a crucial tool used daily in most microbiologists’ work. It’s the stuff that goes in Petri dishes for microbes to grow on. But many microbiologists are unaware of how this substance became so important in the field. A woman named Fanny Angelina Hesse played a significant role in this story, yet she remains largely unknown in microbiology. Dr. Corrado Nai is making it his mission to change this. In this episode, we chat about how he’s writing a graphic novel on the untold story of how Fanny Angelina Hesse introduced agar to the lab, and why it matters. Topics covered in this episode: How Corrado got interested in microbiology, became a science writer, and is now creating a graphic novel about Fanny Angelina HesseWhat agar is how microbiologists use itThe story of Fanny Angelina Hesse and how agar became so important in microbiologyHow little-known Fanny Angelina Hesse isNew historical material Corrado uncoveredThe upcoming graphic novel about Fanny Angelina HesseAt-home microbiology activity: Discovering the Microbial World: Create Your Own Agar PlatesJOYFUL MICROBE SHOW NOTES: https://joyfulmicrobe.com/fanny-hesse-corrado-nai/ AT-HOME MICROBIOLOGY ACTIVITY: https://joyfulmicrobe.com/create-agar-plates/ JOYFUL MICROBE TWITTER: https://twitter.com/joyfulmicrobe/ JOYFUL MICROBE INSTAGRAM: https://www.instagram.com/justineldees/ SUPPORT JOYFUL MICROBE: https://ko-fi.com/joyfulmicrobe/

    Are Oysters Safe to Eat Raw? Understanding the Microbes and Risks: Dr. Rachel Diner

    Oysters can be risky to eat raw, but what microbes are actually responsible? Is there more to it than just chance? In this episode, I talk with Dr. Rachel Diner, Assistant Professor at the University of Memphis researching aquatic microbes, to find out. Here, we discuss the hidden world of bacteria in oysters, exploring the roles these organisms play in the environment and their impact on human health. Our conversation digs into the complexities of Vibrio bacteria and the environmental conditions that influence their prevalence, but it’s also full of practical advice. Listen to the episode to learn how there’s a lot more to the story when it comes to oysters and the bacteria they harbor.

    The Impact of Alcohol on the Gut Microbiome: Andrew Day

    Can drinking alcohol impact our gut health? It sure can. Since our gut health is so crucial for our overall health, this episode focuses on the connection between alcohol consumption and the microbial component of our gut health, the gut microbiome. In this episode, I spoke with microbiology researcher Andrew Day about how alcohol disrupts the gut microbiome and mycobiome — the fungal community in the gut — causing changes that affect the body and brain. We explore whether quitting alcohol can heal the gut and the potential of future therapies like probiotics or fecal transplants to aid recovery. Join us to learn about the gut microbiome’s surprising role in addiction and what science is uncovering about this complex relationship. By understanding these connections, we gain insight into the broader impacts of alcohol on health and behavior. Topics covered in this episode: The role of fungi in the microbiomeImpact of alcohol on the gut microbiome (and mycobiome)Recovery and microbiome restorationThe gut microbiome and addictionThe gut-brain axis and alcohol consumptionPotential of microbial therapies for recovery: probiotics, prebiotics, fecal transplantsAt-home microbiology activity: Grow a biofilm JOYFUL MICROBE SHOW NOTES: https://joyfulmicrobe.com/alcohol-gut-microbiome-andrew-day/ JOYFUL MICROBE TWITTER: https://twitter.com/joyfulmicrobe/ JOYFUL MICROBE INSTAGRAM: https://www.instagram.com/justineldees/ SUPPORT JOYFUL MICROBE: https://ko-fi.com/joyfulmicrobe/

    Degrading Plastic Through the Power of Microbes: Angie Beckett

    Plastic waste in our oceans is a significant problem, but some bacteria might offer a solution. Did you know that certain bacteria can break down plastic? Plastic pollution affects wildlife and can even enter our food and water. As plastic production increases, finding better ways to manage this material is essential. Current recycling methods are not very efficient. Most plastic ends up in landfills or the environment after just one use, and it can take centuries to degrade. Researchers are investigating plastic-degrading microbes and enzymes that could improve recycling. These microbes can break plastic into its original building blocks, allowing for more effective recycling. Join me as I talk with Angie Beckett, a researcher at the University of Portsmouth, about the potential of plastic-degrading microbes to enhance recycling and reduce plastic pollution. In this episode, we will explore: The discovery of plastic-eating bacteriaHow microbes break plastic down and their potential for large-scale useChallenges in finding and engineering efficient plastic degradersUsing portable DNA sequencing to discover new microbial solutionsThe importance of collaboration in applying microbiology to real-world problemsAt-home microbiology activity: Find Plastic-Degrading Bacteria via Sequencing SimulationJOYFUL MICROBE SHOW NOTES: https://joyfulmicrobe.com/plastic-degradation-angie-beckett/ AT-HOME MICROBIOLOGY ACTIVITY: https://joyfulmicrobe.com/plastic-degrading-bacteria-activity/ JOYFUL MICROBE TWITTER: https://twitter.com/joyfulmicrobe/ JOYFUL MICROBE INSTAGRAM: https://www.instagram.com/justineldees/ SUPPORT JOYFUL MICROBE: https://ko-fi.com/joyfulmicrobe/
