Nothing at all to do with the above strand that the bacteria are attached to but very cool

And more cool research on bacteria immune system that just got published yesterday

I did get a closer look tonight at Vibrant. And I keep wondering if I've done something to cause those stands to appear. I'm starting to think not. Especially since I haven't seen them in any other samples I've ever done with bacteria in a bottle, in tank's samples, or many other samples I've done with my son from around the house, body, and yard.

Uploading pics and vids now. To make sure it wasn't how I prepared (cleaned/sterilized) the slides I looked at a sample completely unprepared. Thinking maybe it's the cover slip somehow I viewed another sample with out the coverslip and in a well slide. Then used a little stain and rinsing. Etc.

Found strands in every instance. In some cases I found lots as if I smeared the sample and stain which I didn't.

Then the last sample I looked at I found the mother of all lines...

No idea what it is. It doesn't stain with violet or iodine or safranin. But that last "line" was very interesting and had a few even thinner stands starting off it.


Edit :
it's not entirely dormant. There was some active movement.

So, now for some stain. Just did a basic gram stain process: cleaned the slide, added the sample, burned it onto the slide, added some violet, rodi rinsed, added some iodine, rodi rinsed, light ethyl alcohol rinse, rodi rinse, add some safranin, final rodi rinse, and dry.

And, after all that, still there. But in this third sample for the night I found a monster of a strand.

And last night I took a look at the 3rd sample I've been wanting to get to and found something that now makes me wonder if the strands above in the Vibrant bottle aren't algae based. I wasn't think it was algae based at all as they are thin to extremely thing strands.

BUT I found this (more photo's from last night to come)

Some kind of strand seen in the algae

If they were more uniformed shaped, we'd call them wipers :p :D

Can you confirm that those strands are not something I'm doing to contaminate the samples? Or even confirm what those strands are that bacteria are clinging to? Email is fine too? ;)
