there's no place like chrome



Well my little study has turned out inconclusive, pretty much as expected. The only really interesting thing going on here is that it is the chrome green my many-headed friend has chosen to pick up and run around with.  That was the Serratia marcescens' favourite too, I wonder what the fascination is with Cr2O3  for the microorganisms...

    Nice pictures!

    Well, Chromium(III) (is the one in Cr2O3) is not as toxic as Cr(VI), but has effects in bacterial growth. (http://www.ncbi.nlm.nih.gov/pubmed/17934697). It has been described that in some cases Cr(III) stimulates growwth of E. coli (sorry! it is in Spanish language http://www.scielo.cl/pdf/infotec/v21n1/art09.pdf)
