study of bacterial community structure in Asian desert surface sand samples
study of bacterial community structure in Asian desert surface sand samples
Arid regions represent nearly 30% of the Earth’s terrestrial surface. They thus correspond to important ecological models, but their microbial biodiversity is not well characterized. Using pyrosequencing of 16S rDNA sequences amplified by PCR from total DNA extracted from surface sand samples, we examined three samples from the Taklemaken desert (China) and two samples from the Gobi desert (Mongolia).
