Abundance, diversity and spatio-temporal dynamics of nirS gene-harbouring denitrifiers in a potato field over the course of a growth season

The abundance and diversity of nirS-harbouring bacteria were evaluated in a potato field during a growth season using culture-independent techniques. A total of 182 operational taxonomical units were identified and most had low homology to known nirS sequences, which suggested the discovery of new d...

More Information
Summary:The abundance and diversity of nirS-harbouring bacteria were evaluated in a potato field during a growth season using culture-independent techniques. A total of 182 operational taxonomical units were identified and most had low homology to known nirS sequences, which suggested the discovery of new denitrifiers. The diversity was significantly higher in the furrow, followed by the hill and the near-plant region and was inversely proportional to the denitrification enzyme activity. In contrast, the abundance was not altered by soil locations but was significantly lower at the end of the growth season.
