    Notes: The complete single copy fdh operon (∼5.7 kb) encoding the formate dehydrogenase subunits of the gram negative, reductively dehalogenating anaerobe Sulfurospirillum multivorans was sequenced and analyzed. The gene fdhA encoding the catalytically active periplasmic subunit is part of an operon (fdhEABCD) containing additional structural genes. The genes fdhEABCD were cotranscribed as indicated by RT-PCR and primer extension experiments. Two mRNAs for fdhEABCD and fdhABCD were either transcribed independently from two transcription start sites upstream of fdhE and fdhA or might result from posttranscriptional processing of the full-length fdhEABCD mRNA. The operon shows a high degree of similarity to the fdh operons of Campylobacter jejuni and Wolinella succinogenes in terms of architecture and putative cofactor binding motifs of the gene products.

    Notes: Abstract Marine luminescent bacteria of the genera Vibrio and Photobacterium as well as Photorhabdus (Xenorhabdus) luminescens, an enterobacterium mutualistically associated with insect pathogenic soil nematodes, display different levels of salt tolerance when grown on nutrient broth medium (5% w/v NaCl for marine species and 3% w/v for Prb. luminescens). Osmolytes (compatible solutes) synthesized and/or accumulated for haloadaptation were identified using HPLC techniques and 13C-NMR spectroscopy. All species investigated in this study accumulated betaine and ectoine (1,4,5,6-tetrahydro-2-methyl-4-pyrimidine carboxylic acid) from the medium under elevated osmotic conditions. External supply of osmolytes improved both growth and salt tolerance. Only species belonging to the genus Vibrio were able to synthesize the compatible solute ectoine de novo. Glutamate also participated in osmoadaptation while trehalose was only found in V. fischeri species. In Prb. luminescens13C-NMR spectroscopy also revealed the presence of choline when grown on complex medium.
