[Microbial characteristics and eco-health implication of mineral spring water in Wudalianchi, Northeast China].

Mineral spring water is a top quality potable groundwater resource formed by long-term groundwater-rock interaction in aquifer. Mineral spring water is rich in minerals and trace elements which are beneficial for human health. Given the current serious water pollution and environment deterioration, it is of great significance to re-recognize the ecological and health effects of mineral water based on new scientific and technological achievement.

Low-temperature biodegradation of aniline by freely suspended and magnetic modified Pseudomonas migulae AN-1.

Aniline is of great environmental concern with regards to widespread occurrence in water and soil and increasing threat into the life forms. Bioremediation involving the use of degrading bacterium in the removal of aniline is the most promising process, yet inhibited under low temperature usually. In the present study, a new psychrotrophic bacterial strain isolated from groundwater, designated AN-1, was shown to be capable of aniline degradation in a concentration range of 135-2202 mg L(-1) within 72 h at 10 °C.
