It's a biofilm!
( meme joke! http://digitalclaritygroup.com/wordpress/wp-content/uploads/2012/08/trap.png )

Definately mucosal strands - could be biofilms shed from their stronghold.

Biofilms are parasitic gut colonies. They contribute to malnutrition. :o


Biofilm life cycle and how it works

I recently started brewing kombucha tea and ordered a starter.

Here's what a kombucha 'mother', or SCOBY (Symbiotic community of yeast and bacteria) looks like:

When I tried to break my scoby into pieces for use in several types of tea, I could not rip it! I couldn't pinch it off with a plastic spoon and the glass edge of a bowl! I had to cut it with scissors. You're not supposed to touch live cultures with metal. :o

"Biofilms probably comprise the normal environment for most microbial cells in many natural and artificial habitats, and as such are complex associations of cells, extracellular products and detritus either trapped within the biofilm or released from cells which have lysed as the biofilm ages (Christensen, 1989⇓ ). The main ‘cement’ for all these cells and products is the mixture of polysaccharides secreted by the cells established within the biofilm. Probably the nearest analogy is processed food, in which a mixture of macromolecules of all types interact in various ways to form a recognizable structure. Within such a structure, cells, water, ions and soluble low-and high-molecular-mass products are trapped. In many biofilms, as in food, the hydrated polysaccharides may be in a semi-solid state. The major component in the biofilm matrix is water – up to 97% (Zhang et al., 1998⇓ ), and the characteristics of the solvent are determined by the solutes dissolved in it. The exact structure of any biofilm is probably a unique feature of the environment in which it develops."

Sugar-based matrix of molecules are the cement(s) used by biofilms:
"Polysaccharides are polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages and on hydrolysis give the constituent monosaccharides or oligosaccharides. They range in structure from linear to highly branched."
(Saccharide / carbohydrate == Sugar molecules)
