arthrobacter flavus sp. nov., a psychrophilic bacterium isolated from a pond in mcmurdo dry valley, antarctica. | cms 19yt, a psychrophilic bacterium, was isolated from a cyanobacterial mat sample from a pond in antarctica and was characterized taxonomically. the bacterium was aerobic, gram-positive, non-spore-forming, non-motile, exhibited a rod-coccus growth cycle and produced a yellow pigment that was insoluble in water but soluble in methanol. no growth factors were required and it was able to grow between 5 and 30 degrees c, between ph 6 and ph 9 and tolerated up to 11.5% nacl. the cell wall peptidogly ... | 2000 | 10939663 |
16s rdna diversity of cultured and uncultured prokaryotes of a mat sample from lake fryxell, mcmurdo dry valleys, antarctica. | the prokaryotic diversity of aerobic and anaerobic bacterial isolates and of bacterial and archaeal 16s rdna clones was determined for a microbial mat sample from the moated region of lake fryxell, mcmurdo dry valleys, antarctica. among the anaerobic bacteria, members of clostridium estertheticum and some other psychrotolerant strains dominated whereas methanogens and other archaea were lacking. isolates highly related to flavobacterium hibernum, janthiniobacterium lividum, and arthrobacter flav ... | 2001 | 11302499 |
