well water and sulfur bacteria as a contaminant in scoby?

[Guest guest]

I acquired a scoby last year and it seems to produce a trace of sulfur

smell in the brew.

I have tried different teas/white sugar brands/bottles water brands

and does not seem to matter, the bad smell is always there sometimes

even stronger(it was compared to bottled GT smell).

Was this other culture I got contaminated with sulfur smelling

bacteria and it keeps regrowing it,reproducing in every new scoby?

The smell is like the smell of house well water(a friend has one and

it is just like that smell).This bacteria seems to survive the hi heat

from the water heaters also.

I know other people have asked about the foul smell but has anyone

made the correlation with this water bacteria as a contaminant in the

scoby? and this contaminated scobys are being shipped all over shared

or sold.

Is there a way to get rid of it or just compost the scoby s?

I have always used distilled or drinking bottled water and I know

about sanitation, I brew beer and grew mushrooms successfully before.
