Hello,

Whether specific microbes are attracted to specific chemicals/
substances?

If we dissolve any salt or other substance in water and keep it in
open for 5 to 30 minutes, some microbes from surrounding environment
can be attracted.

Whether those microbes will be salt/substance specific or all type of
microbes in surrounding will be attracted and pollute water?

Best wishes.

Generally, microbes don't move large distances by themselves (large
distances in microbial terms being in the millimetre range)- they get
dispersed by other factors (wind, water droplets, sneezing and coughing) and
they tend to be attached to other things (eg skin flakes, dust). What you
will have in your sample after environmental exposure will be whatever has
fallen into it. If that includes microbes, then the substance in the water
might influence whether they can survive or grow - not much will grow in 70%
ethanol in water, but quite a few things might like 1% glucose in water.

Some moulds have dispersal mechanisms that eject spores for distances of 1 -
2 mm, enough to get through the boundary layer round the object they're on -
which allows better wind dispersal (look up "Sporobolomyces" for more
information.)

Thanks. I thought they can move towards their liking material and
pollute.

Some microbes can move in liquids and have structures (cilia or flagella)
that propel them. The distances they move are typically very small. Some
microbes (like fungi and slime moulds) can respond to chemicals by growing
toward or away from them. But nothing I know of can move by itself across
the distances you're discussing.

The source of that may be the water itself. If you put some salt, sugar
etc. in it, it will begin to flow. With the starting dissolution of the
salt there will be a concentration gradient. The water will flow to the
site with the higher concentration of the salt and the microbes will
move with the stream.
