BACTERIA AND YEASTS OF SCHIRMACHER OASIS, ANTARCTICA : TAXONOMY, BIOCHEMISTRY AND MOLECULAR BIOLOGY (15th Symposium on Polar Biology)
Water and soil samples from Schirmacher Oasis, Antarctica were found to contain a heterogenous group of psychrotrophic bacteria and yeasts. The bacteria belong to the genera Pseudomonas, Sphingobacteriwn, Micrococcus, Planococcus and Arthrobacter. The yeasts belong to the genera Rhodotorula, Bullera...
