biostudies-literatureUnknown48Yusof A<i>Serinicoccus kebangsaanensis</i> sp. nov strain P2D13-UKM is a new species of Gram-positive bacteria isolated from a toxic diatom, <i>Nitzschia navis-varingica</i>. It is a halophilic aerobic, oxidase-negative, catalase-positive, circular, and colonies with white colour. Based on the 16S rRNA gene, the closest species were <i>Serinicoccus profundi</i> MCCC 1A05965 strain 0714S6-1, 97.41%, and <i>Serinicoccus hydrothermalis</i> strain JLT9, 97.35%. This bacteria's predominant cellular fatty acids were iso-C15: 0 (30.1 %) and iso-C16: 0 (16.2 %). The polar lipids identified in this bacterium were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, and an unknown glycolipid. The whole-genome sequence analysis of strain P2D13-UKM showed less than 85% similarity from other <iNew microbes and new infections101005https://www.ebi.ac.uk/biostudies/studies/S-EPMC9399161biostudies-literature<i>Serinicoccus kebangsaanensis</i> sp. nov: A new bacterium isolated from the toxic diatom<i>, Nitzschia navis-varingica</i>.PMC9399161Ahmad ASahrani FKYusof AUsup GBunawan Hfalse<i>Serinicoccus kebangsaanensis</i> sp. nov: A new bacterium isolated from the toxic diatom<i>, Nitzschia navis-varingica</i>.<i>Serinicoccus kebangsaanensis</i> sp. nov strain P2D13-UKM is a new species of Gram-positive bacteria isolated from a toxic diatom, <i>Nitzschia navis-varingica</i>.
