Abstract

Abstract: Culturable bacteria were isolated from 16 soil samples collected from Fildes Peninsula during the 29th Chinese Antarctic Scientific Expedition. Classification and phylogenetic analysis based on 16S rDNA showed that the 67 bacteria belonged to 3 classes and 13 genera. The predominant phyla were Actinobacteria and Proteobacteria and the predominant genera were Arthrobacter and Pseudomonas. The soil properties at four typical sites influenced by humans, seals, and penguins were analyzed. Preliminary analyses of the relationships between soil properties and bacterial diversity and community were conducted. The results showed that bacterial diversity and community were affected by humans, seals, and penguins at different levels. Overall, eight amylase-producing bacteria were found in this study.

Key words: Antarctica, Fildes Peninsula, culturable bacteria, phylogenetic analysis, soil properties
