Some species of extremely halophilic archaebacteria, Halobacteriaceae, have been shown to accumulate large amounts of poly(P-hydroxybutyrate) under conditions of nitrogen limitation and abundant carbon source. The production of poly(P3-hydroxybutyrate), at least in large quantities, was restricted to two carbohydrate-utilizing species,...

A plasmid has been isolated for the first time from moderately halophilic eubacteria. Halomonas elongata, Halomonrrs halmphila, Deleya halophila and Vibrio costkola were found to harbour an 11.5 kbp plasmid (pMH1). The plasmid was isolated and characterized after transformation into Escherichia coh'JM101 cells. A restriction map was...

The tolerance patterns, expressed as MICs, for 250 moderately halophilic eubacteria to 10 heavy metals were surveyed by using an agar dilution method. The moderate halophiles tested included 12 culture collection strains and fresh isolates representative of Deleya halophila (37 strains), Acinetobacter sp. (24 strains), Flavobacterium sp. (28...
