How Do Size and Aggregation of Ice-binding Proteins Control their Ice Nucleation Efficiency. Journal of the American Chemical Society , 2019; DOI: 10.1021/jacs.9b01854 Cite This Page : ...

The formation of these seeds is called ice nucleation. Nucleation is so slow for pure water at zero degrees that it might as well not happen at all. ... The best known ice nucleator is a bacterium ...

Scientists first spotted biological ice nucleation in the 1970s when studying the bacteria Pseudomonas syringae, a plant pathogen that causes multiple diseases in crops.

A harmless bacterium, Pseudomonas syringae, lives on many plants and contains an "ice nucleation" protein that promotes frost damage. (Ice nucleation proteins, which are found on the surface of ...

An ice crystal needs to form around a nucleus, which can be a bit of dust, soot, pollen, or, as we’ve seen, bacteria. Pure water doesn’t have to crystallize into ice until it’s as cold as 55 ...

ICE, ICE BABY Pseudomonas syringae bacteria can freeze water at above-freezing temperatures, so they’re often used to help make artificial snow for ski slopes. Mr. Green/Shutterstock Share this: ...

For instance, the bacterium Pseudomonas syringae produces proteins that stimulate the production of ice crystals in a process called ice nucleation. “It sort of kick starts the freezing process at ...

And plant pathogens, particularly the bacterium Pseudomonas syringae, ... This is the process called nucleation. Ice-nucleating proteins, such as those in Ps. syringae, ...
