Arthrobacter roseus sp. nov., a psychrophilic bacterium isolated from an antarctic cyanobacterial mat sample.

Abstract: Strain CMS 90rT, a red-pigmented bacterium, was isolated from a cyanobacterial mat sample from a pond located in McMurdo, Antarctica. Based on its chemotaxonomic and phylogenetic properties, strain CMS 90r(T) was identified as a member of group I of Arthrobacter. It shared 16S rDNA similarity of 98% with Arthrobacter oxydans ATCC 14358T and Arthrobacter polychromogenes ATCC 15216T, while DNA-DNA similarities determined for these three organisms were less than 70%. It also differed from all 17 reported Arthroba… Show more

“…EME-98-03 had high 3 H-thymidine uptake, whereas 3 H-leucine uptake was indistinguishable from formalinkilled controls. In general, the rates of 14 C incorporation were low relative to 14 C respiration, suggesting the microbes were not in balanced growth under these conditions. The uptake signal from MilliQ rinse water was also indistinguishable from controls.…”

“…3 A and B; SI Table 3). Overall, DLE-98-12 meltwater displayed more extensive 3 H-leucine and 14 C uptake, as well as 14 C respiration, compared with the older ice. EME-98-03 had high 3 H-thymidine uptake, whereas 3 H-leucine uptake was indistinguishable from formalinkilled controls.…”

“…Furthermore, the topology of the tree was similar to the one reported previously (Evtushenko et al, 2000). However, although strains CMS 76r T and CMS 81y T show 97?5 % relatedness at the 16S rRNA gene level, they probably represent two distinct species, since the overall genome relatedness between the two, based on DNA-DNA hybridization performed using the membrane filter method of Tourova & Antonov (1987) as described previously (Reddy et al, 2002a), was only 30 %.…”

“…Further, the ability of the cultures to utilize carbon compounds as the sole carbon source was checked by supplementing minimal medium [1?05 % K 2 HPO 4 , 0?45 % KH 2 PO 4 , 0?1 % (NH 4 ) 2 SO 4 and 1?5 % agar, all w/v] with 0?5 % (w/v) of the filter-sterilized carbon compound. Nutrient agar was used to check the sensitivity of Sd/3 T to different antibiotics, using commercial antibiotic discs (HiMedia, Mumbai, India (Venkateswaran et al, 2003;Nagel & Andreesen, 1991); 9, Bacillus firmus ATCC 14575 T (Venkateswaran et al, 2003;Nagel & Andreesen, 1991); 10, B. psychrosaccharolyticus ATCC 23296 T (Larkin & Stokes, 1967); 11, Bacillus alcalophilus DSM 485 T (Fritze et al, 1990;Nielsen et al, 1995;Yumoto et al, 2003); 12, Bacillus clarkii DSM 8720 T (Nielsen et al, 1995); 13, Bacillus halmapalus DSM 8723 T (Logan et al, 2002;Nielsen et al, 1995); 14, B. horikoshii DSM 8719 T (Li et al, 2002;Logan et al, 2002;Nielsen et al, 1995) 1988) and analysed as described previously (Reddy et al, 2002). Isoprenoid quinones were extracted according to the method described by Collins et al (1977) and separated by HPLC using a SB-C 18 Zorbax reverse-phase column fixed to a Hewlett Packard Series 1100 HPLC as described previously (Tamaoka et al, 1983;Suresh et al, 2004).…”
