Louis Pasteur is credited with disproving the theory of spontaneous generation by conducting experiments with beef broth in swan-necked flasks that allowed air to enter, but prevented microorganisms from contaminating the broth. His experiments showed that microorganisms present in the air were responsible for contamination, not spontaneous generation of life.
Louis Pasteur demonstrated through his experiments that organisms do not spontaneously generate in beef broth, refuting the theory of spontaneous generation. He showed that microorganisms present in the air contaminated the broth, leading to growth, thus supporting the concept of biogenesis.
Louis Pasteur showed that organisms do not grow spontaneously in beef broth through his experiments in the mid-19th century. He disproved the idea of spontaneous generation and demonstrated the presence of microorganisms in the air that could contaminate the broth, leading to growth.
Louis Pasteur demonstrated through his experiments that organisms do not grow spontaneously in beef broth. By using swan-necked flasks that prevented airborne particles from contaminating the broth, Pasteur showed that the growth of microorganisms was due to the introduction of pre-existing germs. This experiment led to the rejection of spontaneous generation theory.
Louis Pasteur conducted the famous experiment with the boiled and unboiled broth to demonstrate that spontaneous generation of life does not occur. He showed that only the broth exposed to air developed bacteria, while the boiled broth remained sterile. This experiment provided evidence for the germ theory of disease and the importance of sterilization.
He disproved that living cells come from nonliving things.

The idea of spontaneous generation was famously disproven by Louis Pasteur in the 19th century through a series of experiments. He used swan-necked flasks to demonstrate that microorganisms from the air, not spontaneous generation, caused contamination of sterile broth. By keeping the broth free from airborne microorganisms, he showed that it remained free of life, thereby refuting the idea that living organisms could arise from non-living matter. His work laid the foundation for the germ theory of disease and modern microbiology.
Louis Pasteur's experiment on spontaneous generation in 1861 involved boiling broth in a flask with a curved neck to prevent dust particles from entering. The broth remained uncontaminated, disproving the theory of spontaneous generation and supporting the idea of biogenesis, which states that living organisms can only arise from preexisting living cells.

John Needham's experiments appeared to support the theory of spontaneous generation as he observed microorganisms appearing in broth that had been heated and sealed. However, his conclusions were later challenged by Spallanzani and Pasteur, who showed that organisms did not grow in boiled and sealed containers. Ultimately, Needham's experiments did not definitively disprove spontaneous generation.
He disproved that living cells come from nonliving things.
The idea that life forms can spring from inorganic matter is known as spontaneous generation. Aristotle was the chief Western proponent of this belief which was difficult to dislodge because most people had great difficulty in understanding how tiny insects, for instance, could appear as if from nothing.As a matter of fact, Pasteur did not entirely succeed in providing the required proof; however, he did lead the way. By boiling the beef broth in the flask he left the broth unchanged but extinguished the microbial life in it-or at least most of it. Doubters were pushed to the conclusion that there could be no such thing as spontaneous generation, that there must have been something in the broth that boiling had destroyed. The broth did not go bad.Please see the link for a fuller account.
Louis Pasteur provided experimental proof for Virchow's biogenesis theory by conducting experiments that showed that living organisms only arise from pre-existing living organisms, refuting the theory of spontaneous generation. His swan-neck flask experiment demonstrated that microorganisms in the air did not spontaneously generate in sterile broth, supporting the idea that living organisms come from other living organisms.
Louis demonstrated that the fermentation process is caused by the growth of microorganisms, and that the growth of microorganisms in nutrient broths is not due to spontaneous generation[5]but rather to biogenesis (Omne vivum ex ovo). c. spontaneous generation
