HALOPHILIC AGAR

Halophilic media are formulated for isolation and cultivation of extreme halophilic species of Halobacterium and Halococcus from foods. For optimum growth they require high salt concentration of about 20-30%. In general, the requirement for salt by halophilic microorganisms is not an exclusive need for NaCl since many species require low levels of K +, Mg++ and other cations anions in addition to NaCl. These bacteria can cause pink discoloration on the outer surface accompanied by putrefaction and decomposition of fish, bacon and hides preserved in sea salts.
