Beggiatoa mats on the bottom of a Dutch lake forming white mats

Beggiatoa mats on the bottom of a Dutch lake forming white mats In a bit more detail.

Two photos of the same jar. A bit of sediment and the white hue is Beggiatoa. A few hours after taken the left photo, you see the change of that white hue. These Beggiatoa bacteria are motile and thus move around.

Marine species can also have freshwater cousins.
Just an idea of what these mats look like on the bottom. These are #freshwater ones. It's a useful indicator of anoxic or low oxygen conditions.

some seafloor necromass. At the type locality in @discoverygeoparknl.bsky.social #unesco #geopark
the Lydonia are surrounded by and even over growing #Fractofusus andersoni. I couldn’t get a more fluffy #beggiatoa -like matground to look right so i went with something sparser.

#Beggiatoa the front of it shows a rotating motion. It's also loosing a tail segment. #bacteria #microscopy #sediment sample from 19 mtr depth in #freshwater lake Haarlemmermeerse bos/ Netherlands. #scubadiving #projectbaseline

#Beggiatoa loosing a bit of tail. This video is 16x the normal speed.
