Nitrate and ammonium ions contents in field minibioreactors with Antarctic freshwater autotrophs
The content of nitrate and ammonium ions in aquatic environment is an important factor in the development of microorganisms colonies especially in low-nutrient environment. In this study, field experiments using small-volume minibioreactors were performed directly on the James Ross Island in Antarct...
