Something growing in fairly strong saline solution

I had a strong saline for mouth rinse. Not sure exactly how strong, maybe 75g/litre. Something is growing in it, a white cloudy diffuse-edged thing. This may be 2 to 3 week's growth. Some non-soluble grit at the bottom. Any ideas what grows in high salinity like that. Saline solution is more like 9g/litre I believe. So…

Any ideas what grows in high salinity like that. Saline solution is more like 9g/litre I believe. So this would be e.g. 5 times stronger solution.
See the attached, about 7.5 cm inside diameter base for the glass.

Might not be growing. May be denatured proteins coming out of solution.
Could also be halophiles https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7024382/

Not denatured protein, I think. There was v little if any backwash into the glass. The clumps have grown slowly over weeks.
Halophiles perhaps.

Could it be salt precipitating out of solution?
