Louis Pasteur - Microbiology, Germ Theory, Pasteurization: Fermentation and putrefaction were often perceived as being spontaneous phenomena, a perception stemming from the ancient belief that life could generate spontaneously. During the 18th century the debate was pursued by the English naturalist and Roman Catholic divine John Turberville ...
This idea was referred to as spontaneous generation. By sterilizing cultures and keeping them isolated from the open air, Pasteur found that contamination of the media only occurred upon exposure to the outside environment, showing that some element was needed to give rise to life.
La generación espontánea es un cuerpo de pensamiento obsoleto sobre la formación ordinaria de organismos vivos sin descendencia de organismos similares. Por lo general, la idea era que ciertas formas como las pulgas pudieran surgir de materia inanimada como el polvo o que los gusanos pudieran surgir de carne muerta.
Louis Pasteur's 1859 experiment is widely seen as having settled the question of spontaneous generation. He boiled a meat broth in a swan neck flask ; the bend in the neck of the flask prevented falling particles from reaching the broth, while still allowing the free flow of air.
Explain the theory of spontaneous generation and why people once accepted it as an explanation for the existence of certain types of organisms. Explain how certain individuals (van Helmont, Redi, Needham, Spallanzani, and Pasteur) tried to prove or disprove spontaneous generation.
