A useful screening method for the presence of PHAs is the incorporation of the dye Nile Red into colonies on agar plates and its detection by fluorescence(Spiekermann et al.).The method has been used widely for therapid identification of PHA-producing environmental bacteria,but not yet with archaea.In our experiments,correct predictions from the presence or absence of fluorescent colonies for the production of PHAs were obtained also for haloarchaeal strains.The method can thus be considered compatible with agar plates containing media of high ionic strength.Other methods which were used here included staining for cytoplasmic granules of PHB in cells,which is fast and generally informative.
