Bioprecipitation
Bioprecipitation is the concept of rain-making
Ice-nucleating proteins derived from ice-nucleating bacteria are used for snowmaking. A symbiotic relationship between sulphate reducing, lead reducing, sulphur oxidizing, and denitrifying bacteria was found to be responsible for biotransformation and bioprecipitation. [5]
Plant pathogens
Most known ice-nucleating bacteria are plant pathogens. These pathogens can cause freezing injury in plants. In the
Dispersal of bacteria through rainfall
Bacteria present in clouds may have evolved to use rainfall as a means of dispersing themselves into the environment. The bacteria are found in snow, soils and seedlings in locations, such as, Antarctica, the Yukon Territory of Canada and the French Alps, according to Brent Christner, a microbiologist at Louisiana State University. It has been suggested that the bacteria are part of a constant feedback loop between terrestrial ecosystems and clouds. According to Christine, this bacteria may rely on the rainfall to spread to new habitats, in much the same way as plants rely on windblown pollen grains, which could possibly a key element of the bacterial life cycle.[4]
Snowmaking
Certain species of bacteria and fungi are known to act as efficient biological ice nuclei at temperatures between −10 and 0 °C.
