A few extremely halophilic bacteria were also observed, mostly on Hv-YPC medium and MGM. These media have a substrate composition more complex than CDM and DBCM2, which are supplemented with pyruvate as sole carbon source. Bacterial isolates related to Salinibacter ruber (Camargue salt), Halobacillus alkaliphilus and Pontibacillusmarinus
(Guérande salts), Actinopolyspora halophila (Gozo Island salt) and S. hominis (Marsel® fine salt) (data not shown
