Bacteria in Daily Life

The book takes listeners on a concise journey through the birth of bacteriology, beginning with the startling 19th‑century revelation that yeast, long thought inert, is a living organism. It follows the youthful curiosity of Louis Pasteur and his groundbreaking experiments that finally proved fermentation depends on living microbes. By tracing these milestones, the narrative shows how a once‑obscure microscopic world reshaped industry, medicine, and everyday understanding of food and drink.

Beyond the laboratory, the work reveals how bacteria are the unseen custodians of decay and renewal, breaking down everything from weeds to whales. Their astonishing ability to multiply in minutes, survive extreme temperatures, and thrive without food underscores their resilience and indispensable role in keeping ecosystems clean. Listeners will discover how modern science harnesses these tiny powerhouses for everything from brewing to hygiene, highlighting the profound ways microbes support life on a daily basis.
