Marinobacter psychrophilus sp. nov., a psychrophilic bacterium isolated from the Arctic

Marinobacter salarius sp. nov. and Marinobacter similis sp. nov., Isolated from Sea Water

Two non-pigmented, motile, Gram-negative marine bacteria designated R9SW1T and A3d10T were isolated from sea water samples collected from Chazhma Bay, Gulf of Peter the Great, Sea of Japan, Pacific Ocean, Russia and St. Kilda Beach, Port Phillip Bay, the Tasman Sea, Pacific Ocean, respectively. Both organisms were found to grow between 4 °C and 40 °C, between pH 6 to 9, and are moderately halop...

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 bet...

Psychrophilic Lipase from Arctic Bacterium.

A lipase producer psychrophilic microorganism isolated from Arctic sample was studied. The genomic DNA of the isolate was extracted using modified CTAB method. Identification of the isolate by morphological and 16S rRNA sequence analysis revealed that the isolate is closely related to Arthrobacter gangotriensis (97% similarity). A. gangotriensis was determined as positive lipase producer based ...

Marinobacter goseongensis sp. nov., from seawater.

A Gram-negative marine bacterium, designated strain En6(T), was isolated from seawater of the East Sea of Korea. The organism grew in 1-25 % (w/v) NaCl and at 10-37 degrees C and pH 5.3-9.3, with optimal growth occurring in 4-5 % NaCl and at 25-30 degrees C and pH 7.5. Phylogenetic analysis of the 16S rRNA gene sequence of strain En6(T) placed this bacterium in the clade Marinobacter within the...

Marinobacter nitratireducens sp. nov., a halophilic and lipolytic bacterium of the family Alteromonadaceae isolated from coastal surface sea water
