NITRIC-OXIDE COMPLEX OF IRON(II) MYOGLOBIN CONVERTED FROM METMYOGLOBIN BY STAPHYLOCOCCUS-XYLOSUS

With Staphylococcus xylosus FAX-1, metmyoglobin in MRS broth (pH 5.8) was found to undergo conversion to hexacoordinate nitric oxide (NO) co mplex of Fe(II) myoglobin. When the pH of the MRS culture containing m yoglobin changed from 5.8 to 4.0, it affected the conversion from hexa coordinate to pentacoordinate NO complex of Fe(II) myoglobin, This con version process was reversible. Salami without nitrite or nitrate addi tion was prepared by inoculating S. xylosus FAX-1, and pentacoordinate NO complex of Fe(II) myoglobin (nitrosylmyoglobin formed in cured mea t) was formed in the salami.
