Nitrosospira lacus is the 4th Nitrosospira species described. It is a sole representative of Cluster 0 Nitrosospira. APG3T was isolated from a shallow lake sediment in 2008 (Green Lake, WA, USA). Strain APG3T can grow at 4 °C but cannot grow at 35 °C, indicating that this bacterium is psychrotolerant. It should be noted that the strain is able to grow over a wide range of pH (pH 5–9), which is greater than the pH range of any previously reported ammonia-oxidizing bacteria in pure culture. However, the optimum pH is between 7.0 to 8.0, thus, APG3T is acid tolerant and not acidophilic. Some ammonia-oxidizing archaea show better adaptation to low pH soil environments (Lehtovirta-Morley et al. 2011). One another unique feature of this bacterium is that N. lacus is only Nitrosospira species that can grow at 4C. Thus, this bacterium is psychrotolerant. | |||

Description and significance
Nitrosospira lacus is the 4th Nitrosospira species described. It is a sole representative of Cluster 0 Nitrosospira. APG3T was isolated from a shallow lake sediment in 2008 (Green Lake, WA, USA). Strain APG3T can grow at 4 °C but cannot grow at 35 °C, indicating that this bacterium is psychrotolerant. It should be noted that the strain is able to grow over a wide range of pH (pH 5–9), which is greater than the pH range of any previously reported ammonia-oxidizing bacteria in pure culture. However, the optimum pH is between 7.0 to 8.0, thus, APG3T is acid tolerant and not acidophilic. Some ammonia-oxidizing archaea show better adaptation to low pH soil environments (Lehtovirta-Morley et al. 2011). One another unique feature of this bacterium is that N. lacus is only Nitrosospira species that can grow at 4C. Thus, this bacterium is psychrotolerant.
