According to a study by a Pune-based institute, the colour of water in Lonar lake in Maharashtra’s Buldhana district turned pink in June 2020 due to a large presence of the salt-loving Haloarchaea microbes.
About:
Haloarchaea (or halophilic archaea) are aa class of the Euryarchaeota, found in water saturated or nearly saturated with salt.
Halobacteria are now recognized as archaea, rather than bacteria and are one of the largest groups.
These microorganisms are members of the halophile community, in that they require high salt concentrations to grow.
Their high densities in the water often lead to pink or red colourations of the water (the cells possessing high levels of carotenoid pigments, presumably for UV protection).
