How do microbes make ice?

If you’ve ever skied, or ever been in a mountain you've always noticed if the snow is artificial or
not, for some mountains it's unknown, but in other it's very common as there very little snow and
has to be created by canons . To make fresh powder (snow), humans have co-opted a specialized
protein from a bacterium called InaZ that jump-starts the freezing process when water is close to
0°C, but it also has a disadvantage, that added in excess this protein could damage the host
plants.
