Horticoccus luteus gen. nov., sp. nov., A Novel Member of the Phylum Verrucomicrobia Isolated from a Dichlorodiphenyltrichloroethane (DDT)-Contaminated Orchard Soil

Actomonas aquatica gen. nov., sp. nov., a marine lineage in the phylum Verrucomicrobiota with genetic potential for carbon and nitrogen fixation

“…At present, the family Opitutaceae includes eight genera with correct names according to LPSN (https://lpsn.dsmz.de/family/ opitutaceae, accessed on 1 December 2023) [3], namely Alterococcus [9], Ereboglobus [18], Nibricoccus [19], Geminisphaera [20], Oleiharenicola [7], Opitutus [21], Rariglobus [11], and Horticoccus [22]. The genus Alterococcus was recently proposed to represent the family Alterococcaeae, mainly based on 16S rRNA gene phylogeny (no genome sequence is available for the type strain [4,5], but this classification is disputable, as mentioned above).…”

“…The genus Alterococcus was recently proposed to represent the family Alterococcaeae, mainly based on 16S rRNA gene phylogeny (no genome sequence is available for the type strain [4,5], but this classification is disputable, as mentioned above). Members of the family Opitutaceae were discovered mainly in low-salinity environments such as freshwater, termite gut, mantis gut, and rice paddy soil [22], and are described as non-spore-forming, non-motile or motile, aerobic or facultatively anaerobic, chemoorganotrophic, and Gram-stain-negative cocci or coccobacilli [18]. Furthermore, nitrogen-fixation genes and nitrogenase have been reported in Geminisphaera colitermitum TAV2 T [23].…”

“…Differential characteristics between strain WL0086 T and the most closely related species of the family Opitutaceae Strains: 1, WL0086 T ; 2, Oleiharenicola lentus KCTC 62872 T ; 3, Oleiharenicola alkalitolerans ATCC BAA-2697 T[8]; 4, Rariglobus hedericola DSM 109123 T[11]; 5, Nibricoccus aquaticus KACC 19333 T[19]; 6, Opitutus terrae DSM 11246 T[21]; 7, Geminisphaera colitermitum TAV2 T[11]; 8, Ereboglobus luteus DSM 102184 T[18]; 9, Horticoccus luteus DSM 113638 T[22]. Experimental data for strain WL0086 T and Oleiharenicola lentus KCTC 62872 T were obtained from this research, other data were obtained from previous studies.…”
