I don't think sulphate can be used as electron donor. It is a good electron acceptor and a lot of heterotrophs reduces sulphate. Sulphate reducing is a very energetically favorable reaction.

sbdy fixed this already. it was sulfides... uuuǝıɹ 11:17, 17 May 2013 (UTC)[reply]

alternative to photosynthesis

I'm afraid I'd just end up messing up the page if I tried to edit it, but stating that it is an alternative to photosynthetic carbon fixation is categorically false. Many organisms are capable of using photosynthesis to fix CO2 into organic carbon using the rTCA cycle, including Green sulfur bacteria (the Chlorobiaceae). A more accurate statement would be: the rTCA cycle is an alternative to the <Calvin-Benson-Bassham> pathway used by plants and cyanobacteria. —Preceding unsigned comment added by 128.175.254.215 (talk) 03:10, 21 May 2010 (UTC)[reply]
