As for archaea is concerned, PHA production to date, however, has been limited to haloarchaeal species, particularly the genera Haloferax, Halalkalicoccus, Haloarcula, Halobacterium, Halobiforma, Halococcus
, Halopiger, Haloquadratum, Halorhabdus, Halorubrum, Halostagnicola, Haloterrigena, Natrialba, Natrinema, Natronobacterium, Natronococcus, Natronomonas and Natronorubrum (18).
Identification of polyhydroxyalkanoates in Halococcus

The nucleotide sequence of 16S ribosomal RNA gene of the archaebacterium Halococcus

morrhuae isolated from salt cured fish (Prasad and Seenayya, 2000).
When it reaches 250 g per liter, the salt pits start to turn a spectacular reddish color due to the presence of halophilic bacteria (Halobacterium, Halococcus
, Haloarcula), together with some Volvocalean algae (Dunaliella).
In order to find EPSs with novel and valuable properties, several EPSs from haloarchaea have been isolated and investigated, such as Haloferax, Halococcus
, Haloarcula, Natronococcus, Haloterrigena, and Halobacterium [8-12].
