Halobacteria, members of the domain Archaea, live under extremely
halophilic conditions (4–5 M NaCl) and lower concentrations
of sodium chloride generally cause cell lysis (Meral
et al., 2007). They produce organic solutes which maintain
the concentration of ions inside and outside the cell in order
to keep themselves intact and survive in high saline environments
(Gonzalo et al., 2002; Jan et al., 2007; Torsten et al.,
2007). They are often considered as dependable source for
deriving novel enzymes, novel genes, bioactive compounds
and other industrially important molecules. Protein antibiotics
have potential for application as preserving agents in food
