How does the Winogradsky column differ from Koch’s plate media?
Koch’s media creates a gradient from oxygen-rich conditions at the surface to highly reduced conditions below.
The Winogradsky column is used for culturing viruses.
The Winogradsky column is used for growing extremophiles.
The Winogradsky column uses the kinds of nutrients that feed humans.
The bacteria that Winogradsky isolated can grow only on inorganic minerals.
Suppose Pasteur’s swan-necked flasks containing boiled broth became cloudy twenty-four hours after boiling. Which choice could best explain the turbidity or cloudiness in the broth without supporting spontaneous generation?
Endospores in the broth survived boiling and grew after the broth cooled.
Contaminating organisms in the broth killed by boiling became alive again after the broth cooled.
Chemicals in the broth came together to form living organisms.
The broth allowed light to pass through it with less interference after boiling.
