Abstract

This article aims to illustrate and expand the information published in the article "Simultaneous nitrification and denitrification of hypersaline wastewater by a robust bacterium Halomonas salifodinae from a repeated-batch acclimation" [1]. The data present the salt tolerance of strain Y5 at different salinities (0%, 5%, 10%, 15%, and 20%). The effect of salinity on the morphology of bacteria was observed by scanning electron microscope. The influence of culture conditions including carbon source, C/N ratio, initial pH value, temperature, and shaking speed on bacterial growth and NH₄ ⁺-N removal capability of strain Y5 was investigated by single factor experiments. The enzymatic activities of ammonia monooxygenase (AMO), hydroxylamine oxidase (HAO), nitrite reductase (NIR), and periplasm nitrate reductase (NAP) were measured by extracting the cell-free crude enzymes from strain Y5.
