 In fact, when the genome of the "P. stutzeri" strain DSM4166 was sequenced, it revealed some genes for nitrogen fixation along with 42 genes that coded for major parts of a denitrification complex.Scientists hypothesize that the genes needed to fix nitrogen were acquired by these specific bacterial species through lateral gene transfer.Similar to other bacteria within the "Pseudomonas" genus, "P. stutzeri" strains are heterotrophic organisms that are capable of reducing metals and degrading compounds such as hydrocarbons.Unlike other bacteria within the genus, however, "P. stutzeri" strains are not fluorescent.
