What fungus or bacteria will stain damp cloth with (or show as) a bright pink color?

Question

I accidentaly forgot my damp white towel in my gym bag. When I remember a few days later, and took it our, it was stained with bright pink splooches.

Answer 1

A number of common bacteria produce pigments, some of them pink/red. Some species producing pink/red pigments are:

Micrococcus roseus
Rhodococcus rhodochrous
Serratia marcescens

Answer 2

I don't know about any of those things being pink, I am wondering what colour your bag is. A wet white towel could suck colour out of some materials red is a common colour used in a lot of other colours and would look pink if absorbed by a white towel. wash towel well with bleach, may not get out stain but should eliminate any bacteria.

Answer 3

MOLD:
Signs of a moisture problem include musty odors in the home, as well as characteristic black, gray, white or even pink splotches on your walls, furniture, bathroom tile or clothes.

* Any kind of mold can make you sick.
* All molds may be allergenic, whether alive or dead.
* Testing for mold is usually not feasible.
* You can't compare it to guidelines; there aren't any.
