A pond in Sibbesse, Germany, is currently raising questions. Because it’s purple. In general, there are several reasons for the discoloration of a body of water. In this case, it is believed that the reason for this is bacteria that has spread in the pond, ntv reports.
The Lower Saxony State Agency for Water Management, Coastal Defense and Nature Conservation (NLWKN) explains: “Such typical discolorations often have the background that micro-organisms, small creatures, are active there, and that is most likely purple bacteria here.”
This type of bacteria mainly occurs when the condition of the water body is not optimal. It often only affects small bodies of water. But it can also occur in deep lakes if there is too little oxygen in certain layers.
Bathing not recommended
The discoloration caused by the bacteria is caused by the natural coloring agent carotenoids. This supports photosynthesis, where inorganic substances, such as bacteria, produce organic substances such as oxygen.
Although the bacteria is not as toxic as blue-green algae, for example, experts do not recommend swimming in the pond at the moment. (lrc)
