KR11T cells were Gram-negative, rod-shaped, and motile. The isolated strain grew under photoheterotrophic conditions between 20 and 40 \u00b0C (optimum 22\u201325 \u00b0C), at pH ranges from 6.0 to 9.0 (optimum 7.0). It did not require NaCl for growth but tolerated NaCl concentrations up to 1.5% (w\/v). No growth was observed under photoautotrophic conditions. Strain KR11T showed the highest 16S rRNA gene sequence similarity to the type strains of Stagnihabitans tardus CYK-10T (98.84%), Tabrizicola fusiformis SY72T (95.95%), and Rhodobacter sediminis N1T (95.37%). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain KR11T clusters within the genus Stagnihabitans in the family Paracoccaceae of class Alphaproteobacteria. The whole-genome sequence of strain KR11T comprises 4,085,976 bp with a 65 mol% G+C content. Phylogenomic analysis, including core-genome phylogeny, and the low genomic similarity (&lt;95% ANI and &lt;70% dDDH) to phylogenetically related taxa confirmed the taxonomic separation of strain KR11T at the species level. The distinctive phenotypic traits, chemotaxonomic studies, phylogenetic, and genomic analysis establish strain KR11T as a novel species within the genus Stagnihabitans. Accordingly, we propose the name Stagnihabitans lacustris sp. nov. KR11T (=CCUG 74777T, LMG 31924T), isolated from fresh water.<\/jats:p>","DOI":"10.3390\/microorganisms14051157","type":"journal-article","created":{"date-parts":[[2026,5,20]],"date-time":"2026-05-20T09:12:41Z","timestamp":1779268361000},"page":"1157","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Stagnihabitans\u00a0lacustris sp. nov., an Anoxygenic Photoheterotrophic Bacterium of the Family Paracoccaceae, Isolated from a Eutrophic Pond in Czechia"],"prefix":"10.3390","volume":"14","author":[{"given":"Aditi","family":"Singh","sequence":"first","affiliation":[{"name":"Department of Life Science, Sharda School of Bio-Science and Technology, Sharda University, Greater Noida 201306, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sumeeta","family":"Kumari","sequence":"additional","affiliation":[{"name":"Microbial Type Culture Collection and Gene Bank (MTCC), CSIR Institute of Microbial Technology (CSIR-IMTECH), Chandigarh 160036, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunjan","family":"Vasudeva","sequence":"additional","affiliation":[{"name":"Microbial Type Culture Collection and Gene Bank (MTCC), CSIR Institute of Microbial Technology (CSIR-IMTECH), Chandigarh 160036, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2409-0923","authenticated-orcid":false,"given":"Mohit Kumar","family":"Saini","sequence":"additional","affiliation":[{"name":"Laboratory of Anoxygenic Phototrophs, Centre Algatech, Institute of Microbiology CAS, 37901 T\u0159ebo\u0148, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anil Kumar","family":"Pinnaka","sequence":"additional","affiliation":[{"name":"Microbial Type Culture Collection and Gene Bank (MTCC), CSIR Institute of Microbial Technology (CSIR-IMTECH), Chandigarh 160036, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5412-4541","authenticated-orcid":false,"given":"Karel","family":"Kopejtka","sequence":"additional","affiliation":[{"name":"Laboratory of Anoxygenic Phototrophs, Centre Algatech, Institute of Microbiology CAS, 37901 T\u0159ebo\u0148, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6938-2340","authenticated-orcid":false,"given":"Michal","family":"Kobl\u00ed\u017eek","sequence":"additional","affiliation":[{"name":"Laboratory of Anoxygenic Phototrophs, Centre Algatech, Institute of Microbiology CAS, 37901 T\u0159ebo\u0148, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4053-2904","authenticated-orcid":false,"family":"Nupur","sequence":"additional","affiliation":[{"name":"Department of Life Science, Sharda School of Bio-Science and Technology, Sharda University, Greater Noida 201306, India"},{"name":"Laboratory of Anoxygenic Phototrophs, Centre Algatech, Institute of Microbiology CAS, 37901 T\u0159ebo\u0148, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Garrity, G.M., Bell, J.A., and Lilburn, T.
