Glaciecola mesophila sp. nov., a novel marine agar-digesting bacterium.

Alteromonas-like strains KMM 241(T) and KMM 642, isolated from marine invertebrate specimens, were investigated to clarify their taxonomic position. The novel isolates were aerobic, Gram-negative, motile, slightly halophilic and heterotrophic and hydrolysed polysaccharides. They did not hydrolyse urea, gelatin or casein and produced acid weakly from carbohydrates. The DNA G + C content ranged b...

Draft genome sequence of the novel agar-digesting marine bacterium HQM9.

Strain HQM9, an aerobic, rod-shaped marine bacterium from red algae, can produce agarases and liquefy solid plating media efficiently when agar is used as a coagulant. Here we report the draft genome sequence and the initial findings from a preliminary analysis of strain HQM9, which should be a novel species of Flavobacteriaceae.

Comparison of Schaedler agar and trypticase soy-yeast extract agar for the cultivation of anaerobic bacteria.

Schaedler agar (SA) and Trypticase soy-yeast extract agar (TSYEA), both supplemented with rabbit blood (5%, v/v) and menadione (0.5 mg/liter), were compared with respect to quantitative recovery, quality of growth, and rapidity of growth of selected anaerobic bacteria. The media were stored for 2 to 4 days prior to use in an anaerobic glove box, where all subsequent bacteriological procedures w...

Digesting GWAS

nce upon a time, medical genetics was a relaOtively straightforward business: one gene—one protein—one disease was sufficient to explain most inherited disease and was neatly in keeping with Gregor Mendel’s discovery of alleles with his famous peas. The concept remains a good starting point but the biology of life is somewhat more complex, and increasingly we have become impressed and perplexed...
