The Great Yogurt Experiment: Part II – Mesophilic (room temperature) Heirloom yogurt

Tasting the bacterial diversity and seeing pH difference using yogurt fermentation for microbiology teaching. I love the idea that invisible microbes can change their habitat so much we macro-organisms will pay attention and even help them! After all, people have maintained yogurt cultures for generations. Take for example the Heirloom yogurts from Culture for Health that I have been playing with and am considering sending to my General Microbiology class this semester. One overarching theme in my microbiology class is always that microbial diversity provides multiple solutions to the same “problem”. Diversity Matters! In this case – different combinations of bacteria can take the same milk, break-up the milk sugars, and poop out lactic acid. The lactic acid lowers the pH of the yogurt, which protects yogurt from pathogenic bacteria (molds can still grow though given enough time). Lactic acid gives the tart, sour taste to yogurt. To teach my General Microbiology students that microbes – just by growing – can dramatically change their habitat. This semester students will culture their own yogurt to see and taste the difference! The problem is most store-bought yogurts grow best at 113 °F (45 °C). That’s pretty warm. That was tricky during my

Ask Professor Microbe: Should I buy refrigerated probiotics?

Ask Professor Microbe: Should I buy refrigerated probiotics?

“Hey Professor Microbe” – the text from my next-door neighbor read – “What probiotics are better for me to buy, the ones on the shelf or the ones that are refrigerated?” Professor Microbe (Anne @mostlymicrobes): “Why are you buying probiotics?” Neighbor: “General gut health” PM: “Don’t! Spend the money on PRE-biotics – fruits, veggies, and live fermented foods.” Probiotics are quite the established health fad with over 36.6 billion USD in sales in 2015! WOAH! In general, we don’t need them. The average person who eats a healthy diet full of fruits and vegetables feeds their own personal “probiotics” in their digestive system, primarily the large intestine. Feed what you have. Think whole grains and “Eat a Rainbow” of different colors and kinds of plants. My favorite gut microbiome-food book talking about good eating and the gut microbiome is The Good Gut. For an idea of what my family and I eat, check out my Instagram feed or #feedthemicrobes. “When should a healthy person take probiotics?” Pretty much just after taking wide spectrum antibiotics. These antibiotics kill many different kinds of bacteria – invading pathogens and your native microbes (tetracyclines, cephalosporins, aminopenicillins (ampicillin, amoxicillin)). For people with medical issues, I

Martha Carlin: A Visionary Citizen Scientist Changing Microbiome and Medical Research

Martha Carlin: A Visionary Citizen Scientist Changing Microbiome and Medical Research

Self-trained citizen scientist, Martha Carlin, founds The BioCollective to accelerate microbiome research and therapies. “Bad times have a scientific value. These are occasions a good learner would not miss.” ― Ralph Waldo Emerson His vacant stare told Martha Carlin something was wrong with her 44-year-old husband. Many doctor’s visits later, the diagnosis – Parkinson’s Disease. A systems analyst and expert in turning around companies, Martha Carlin was determined to turn around the doctor’s prognosis that Parkinson’s would kill her husband. So for the next 15 years, she began pouring her energy, time, and disposable income into becoming a self-trained scientist. Starting with one of Michael J. Fox’s book, Martha read hundreds of books about nutrition, disease, and immunology. With the help of a childhood friend who was a college librarian and Googling for unfamiliar terms, Martha read scientific journal articles. Slowly she put together a mind map of different potential genetic and environmental influences that might have led to her husband’s Parkinson’s disease. During Parkinson’s Disease, brain cells stop producing the chemical messages that allow for coordinated movement. Patients gradually lose control of their muscles. As she interviewed Parkinson’s patients, Martha noticed that many had frequently used antibiotics, had chronic strep

Book Review:”Let Them Eat Dirt” – Save Your Child by Saving Their Microbes!

Book Review:”Let Them Eat Dirt” – Save Your Child by Saving Their Microbes!

  “Let Them Eat Dirt: Saving Your Child from an Oversanitized World” provides suggestions for a microbially rich and healthy childhood. Let Them Eat Dirt: Saving Your Child from an Oversanitized World talks directly to parents about the importance of microbes to your young kids. Authors  Brett Finlay, PhD and Marie-Claire Arrieta, PhD have an excellent message – let kids get dirty and quit abusing antibiotics. Let Them Eat Dirt is an engaging read clearly written and written clearly by scientist parents who have been in the “parenting trenches”. This microbiome parenting book is a fun read. Several times I laughed out loud at the references to pregnancy and parenting woes. As a scientist, I appreciated their overall message about the importance of microbes to our health.
