Pseudomonas aeruginosa

"Blue pus is found in certain infections of Pseudomonas aeruginosa as a result of the pyocyanin bacterial pigment it produces" found at http://wapedia.mobi/en/Pus

I am researching an information regarding which microbes produce H2O2. Because green pus is results of the MPO released from Neutrophils( most abundant type of leukocyte) which trigger by H2O2. Is it S. Sanguis produce peroxide? and MPO produce HOCL from H2O2 and result in green pus(?)-- I am guessing, but, a logical and an educational. I have to admitte that I do not know the answer. I found this question very interesting. so I want to contribute by opinion. If my answer is worng then I would love to learn from you all. 🙂

this is given in the link you suggested Despite normally being of a whitish-yellow hue, changes in the color of pus can be observed under certain circumstances. Pus is sometimes green because of the presence of myeloperoxidase, an intensely green antibacterial protein produced by some types of white blood cells. Blue pus is found in certain infections of Pseudomonas aeruginosa as a result of the pyocyanin bacterial pigment it produces; amoebic abscesses of the liver, meanwhile, produce brownish pus. Pus might have a reddish tint to it after mixing with blood. Pus can also have a foul odor.

The derivations of pyocyanin and pyoverdine are of the Greek, with pyo-, meaning pus, cyanin, meaning blue, and verdine, meaning green. Pyoverdine in the absence of pyocyanin is a fluorescent-yellow color.
