Ice-forming bacteria will help to cause artificial rain


In the view of most people, bacteria are associated with infection and disease. However, in fact, parasitic bacteria or pathogens represent a very small part of this huge family.

The functions of bacteria are very diverse. For example, Pseudomonas syringae is able to form ice at high temperatures. Scientists led by Professor Tobias Weidner of the Max Planck Institute for Polymer Research have carefully studied the structure of these bacteria and believe that they can be used to create artificial rain .

To do this, the researchers used a spectrometer, through which it was possible to see how the bacteria interact with water molecules. Previously, it was believed that the bacteria mimicked the structure of ice crystals, thereby inducing water molecules to form an ice lattice.

However, in fact, bacteria create specific water with hydrophilic or hydrophobic regions that repel or, on the contrary, attract water molecules that come into contact with them.

Artificial snow

Bacteria pseudomonas syringae have been used for more than 30 years in high mountain resorts and ski slopes in installations that create artificial snow. In the future, scientists hope with their help to form rain clouds and irrigate the land with rain where it is vital .
