In this study, the Priestia aryabhattai FM5 strain, isolated from soil, was found to be capable of nitrogen assimilation. The NH4+ and NO3\u2212 removal characteristics of P. aryabhattai FM5 were investigated to better understand its removal capability. The optimal conditions for NH4+ removal were pH 8.0, temperature\u201425 \u00b0C, and C\/N ratio\u201420, with sodium succinate as the carbon source. Under the conditions of pH 7.0, temperature\u201435 \u00b0C, and C\/N ratio\u201410, with sodium acetate as the carbon source, strain FM5 reached the highest NO3\u2212 removal efficiency. The genome of FM5 revealed genes involved in assimilatory nitrate reduction and glutamate metabolism, such as nasA, nirA, nrt, glnA, gltB\/D, and gdhA. When cultured in wastewater from soymilk processing with activated carbon for 72 h (h), the NH4+ concentration and chemical oxygen demand (COD) decreased from 29.5 to 4.8 mg\u00b7L\u22121 and 2058.3 mg\u00b7L\u22121 to 295.3 mg\u00b7L\u22121, respectively. This study provides deeper insights into the NH4+ and NO3\u2212 removal-capable bacterial strain FM5 and improves the application of Priestia in wastewater.<\/jats:p>","DOI":"10.3390\/biology15181625","type":"journal-article","created":{"date-parts":[[2026,9,15]],"date-time":"2026-09-15T13:33:42Z","timestamp":1789479222000},"page":"1625","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Characterization and Performance of Priestia aryabhattai for Nitrogen Assimilation of Soymilk-Processing Wastewater"],"prefix":"10.3390","volume":"15","author":[{"given":"Qianqian","family":"Chen","sequence":"first","affiliation":[{"name":"Fujian Key Laboratory of Plant Nutrition and Fertilizer, Institute of Resources, Environment and Soil Fertilizer, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wentao","family":"Yu","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory for Technology Research of Inspection and Quarantine, Technology Center of Fuzhou Customs District, Fuzhou 350001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yushu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Fujian Key Laboratory of Plant Nutrition and Fertilizer, Institute of Resources, Environment and Soil Fertilizer, Fujian Academy of Agricultural Sciences, Fuzhou 350003, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,15]]},"reference":[{"key":"ref_1","first-page":"100265","article-title":"A review on plant-based proteins from soybean: Health benefits and soy product development","volume":"7","author":"Qin","year":"2022","journal-title":"J.
