Who was an Italian abbott and biologist whose scientific investigations followed Needham's experiments on spontaneous generation?
Lazzaro Spallanzani..
What did Lazzaro Spallanzani contributes to microbiology?
He repeated John Needham's experiment in which nutrient fluids (Chicken broth) was put into a sealed flask then heated. The nutrient medium could be stored and microoganisms did not arise from it. This experiment disproved the Spontaneous Generation and paved the way for Pasteur's research. Spallanzani was largely criticised under claims that microorganisms needed oxygen to survive. He was also a pioneer in the fertilization an experiment which he produced with frogs. :) hope that helps.
When were tardigrades discovered?
they were described by the German zoologist Johann August Ephraim Goeze in 1773 and coined the wasserbar name. In 1777, the Italian Lazzaro Spallanzani give it the name tardigrada (wiki).
What was a historical experiment performed to test the theory of spontaneous generation?
In 1668, Italian physician Francesco Redi performed an experiment to test the prevailing theory that maggots were formed spontaneously (abiogenesis) in rotting meat. He took 4 pieces of fresh meat and put them in containers, covering two of the containers with paper and leaving the other two uncovered. In a day or two, maggots appeared in the meat samples that were uncovered, because flies had laid their microscopic eggs in the meat. No maggots appeared on the covered pieces of meat, the ones the flies could not reach. In 1745, however, John Needham experimented with boiling solutions to prevent spoilage in grain. Needham either did not boil his solutions long enough, or accidentally contaminated the results, because he found bacteria that had apparently appeared spontaneously. These results were challenged by the Italian Lazzaro Spallanzani in 1768, and eventually by Louis Pasteur, who proved in 1859 that bacteria existed in the open air but did not form by themselves.
Who favored the theory of spontaneous?
Lazzaro Spallanzani

When did Lazzaro Spallanzani die?
Lazzaro Spallanzani died on February 12, 1799 at the age of 70.
How old was Lazzaro Spallanzani at death?
Lazzaro Spallanzani died on February 12, 1799 at the age of 70.
What is spallanzani's hypothesis?
Spallanzani discovered that the theory of spontaneous generation was incorrect; boiling water is a better sterilizer than hot air; and some microorganisms can live for days in a vacuum before dying...
Who falsified spontaneous generation?
Francesco Redi demonstrated that flies do not spontaneously appear in rotting meat when no eggs have been laid in it. That was in 1668. A century later Lazzaro Spallanzani showed that microbes do not spontaneously form in a static environment. This is not a strict falsification of spontaneous generation, but it sufficed to dispell the notion that abiogenesis was trivial or common.
How old is Lazzaro Spallanzani?
Lazzaro Spallanzani was born on January 10, 1729 and died on February 12, 1799. Lazzaro Spallanzani would have been 70 years old at the time of death or 286 years old today.
