How were Redi's and Pasteur's experiments similar?
Both studied the growth of microbes in broth.
Both studied flies emerging from meat.
Both tested the idea of spontaneous generation.
Both tested whether pasteurization kills microorganisms.

Redi's and Pasteur's experiments were similar : Both tested the idea of spontaneous generation.

Italian surgeon Francesco Redi rehearsed in 1668 that was the entirety of the beginning to oppose the concept that larvae instinctively produce on food dropped out in the allowable air.  He presumed that larvae could only develop when flies were entitled to produce eggs in the food and that the larvae were the offspring of houseflies, not the goods of automatic generation.

Louis Pasteur is recognized with conclusively invalidating the theory of spontaneous generation with his outstanding swan-neck flask analysis. He consequently suggested that “life simply proceeds from life.”
