Do sulfate reducing bacteria ingest their sulfate as solid, or liquid or gas?
I understand that almost all forms of sulfate are solid.. and sulfate can be dissolved in water(thus no longer solid, but liquid).
So, do sulfate reducing bacteria ingest sulfate in its solid form, or do they require it to be dissolved in water?
A similar question in fact, for nitrifying bacteria, though if that's complex I might make it a separate question.
Also, even though it's respiration(which tends to be associated either with the breathing process - in the case of physiological respiration, or with having breathed prior - in the case of cellular respiration), here it's not using a gas. So i'm curious if biologists ever use the word "breathing" for such a process. wikipedia for example, says https://en.wikipedia.org/wiki/Sulfate-reducing_bacteria " In a sense, these organisms "breathe" sulfate.." I wonder if biologists use the term 'breath' in such a general sense(to include consuming a substance dissolved in water), or only in a specific sense of gas or air, or if they don't use the term 'breath' at all. So, how strictly is the term breath defined in biology.
