Low temperatures and high pH generally inhibit the biodenitrification.
Thus, it is important to explore the psychrotrophic and alkali-resisting microorganism for degradation of nitrogen.
This research was mainly focused on the identification of a psychrotrophic strain and preliminary explored its denitrification characteristics.
The new strain J was isolated using the bromothymol blue solid medium and identified as Pseudomonas taiwanensis on the basis of morphology and phospholipid fatty acid as well as 16S rRNA gene sequence analyses, which is further testified to work efficiently for removing nitrate from wastewater at low temperature circumstances.
This is the first report that Pseudomonas taiwanensis possessed excellent tolerance to low temperature, with 15°C as its optimum and 5°C as viable.
The Pseudomonas taiwanensis showed unusual ability of aerobic denitrification with the nitrate removal efficiencies of 100% at 15°C and 51.61% at 5°C.
Single factor experiments showed that the optimal conditions for denitrification were glucose as carbon source, 15°C, shaking speed 150 r/min, C/N 15, pH≥7, and incubation quantity 2.0 × 106 CFU/mL.
The nitrate and total nitrogen removal efficiencies were up to 100% and 93.79% at 15°C when glucose is served as carbon source.
These results suggested that strain J had aerobic denitrification ability, as well as the notable ability to tolerate the low temperature and high pH.
