title: Optimization of the production of a bacteriocin from Haloferax mediterranei Xia3.
abstract: The optimal conditions for the production of the halocin H1, a 31 kDa bacteriocin-like molecule produced by the extreme halophilic Archaea Haloferax mediterranei Xia3 active against Gram-negative haloarchaea, was characterized. The physico-chemical conditions required for the optimal production of halocin H1 are similar to those found in the habitat in which the microorganism was isolated: 20% salt concentration and temperature range between 37 and 42 degrees C. Optimal antimicrobial activity was obtained using 0.5% of N-Z amine E as nutrient.
