It tells you what it is on the top of page 30....

No

the white precipitate is something different.
I see that too.
Its not that !

Its a clear (transparant) slimy thing.


They mention both a white precipitate AND a gelatinous lysate....

But anyway, could it be just due to the fact of mixing two different liquids together of different salt conc./densities/etc? For example, when you add an enzyme to a solution, you can see a "slime" (due to the glycerol in the buffer) until you've mixed it properly. It could be something like that?

It could be yes.
I dont know.
I think its the DNA , but not sure why it forms this slime...

Lysing your cells sets free its components, membrane macromolecules i.e. glycoproteins which are able to build intermolecular networks causing the formation of gel-like liquid or so-called "slime".
