Is this Beggiatoa
Gliding filamentous bacteria, I suspect Beggiatoa maybe someone can confirm.

Most likely. If you have DF , the sulphur inclusions will iridesce. Identification to some degree depends on the origin of the sample. Proximity to sewage is a common origin. Eutrophicated lake beds. Any aquatic habitat with a high level of biological oxygen depletion, such as a swamp with yearly cascades of leaf litter. Old wells.

Can't help with the ID but do like the video.
Quite mesmerizing. Fun to see how it seemed at times to be flowing (as if through a tube) rather than moving.

You are pretty dead on with that. Athough the method of movement isn't 100% understood, they do lay down a bioslime that allows them to slip through a tube like film. Their close relative thioploca sp., aggregate , like spaghetti in it's plastic sleeve, forming a bioslime tube in which a group can locomote.

I picked a small cotton-like piece of scum onto a from a jar of putrid water. I added way too much nutrients (rye and boiled maize kernels) to an old jar of pond water and all the little critters died as a result of massive bacterial overgrowth. The bacteria from the video have colonized the bottom of the jar, its kind neat actually. I had a look at them under polarized light and I could see a tiny Maltese cross where the granules are.apochronaut wrote: ↑Mon Dec 14, 2020 12:58 pmMost likely.

That's exactly what went through my head when I decided to film them.
