abstract= Two novel actinobacteria, designated YIM 121936T and YIM 121940T, were isolated from alkaline sediment in Yuanjiang, China. The cells of the novel strains were Gram-stain-positive, aerobic, motile, non-spore-forming and coccus-shaped. The two strains both contained meso-diaminopimelic acid as the diagnostic diamino acid. The whole-cell sugars were arabinose, galactose, glucose, mannose and ribose. The predominant menaquinone was MK-9(H2). The polar lipid profile of both strains comprised diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, phosphatidylinositol mannoside, one unknown phosphoglycolipid and five unknown phospholipids. The predominant fatty acids of both strains were anteiso-C15 : 0. The genomic DNA G+C contents of strains YIM 121936T and YIM 121940T were 74.7 and 75.2 %, respectively. Strain YIM 121936T was closely related to Kineococcus aurantiacus IFO 15268T (97.19 %), Kineococcus gypseus YIM 121300T (97.00 %) and Kineococcus mangrovi NBRC 110933T (97.00 %). Strain YIM 121940T was closely related to K. aurantiacus IFO 15268T (97.41 %), Kineococcus endophytica KLBMP 1274T (97.18 %), Kineococcus rhizosphaerae RP-B16T (97.09 %), Kineococcus radiotolerans SRS 30216T (97.09 %), K. gypseus YIM 121300T (97.00 %) and K. mangrovi NBRC 110933T (97.00 %). Strain YIM 121936T shared high 16S rRNA gene sequence similarity (99 %) with YIM 121940T. Similarities of two strains with other species of the genus Kineococcus were <97 %. The DNA–DNA hybridization values were below 70 % among all the strains studied. YIM 121936T and YIM 121940T are representatives of two new species in the genus Kineococcus , for which names Kineococcus terreus sp. nov. (type strain YIM 121936T=KCTC 39738T=DSM 102155T) and Kineococcus aureolus sp. nov. (type strain YIM 121940T=KCTC 39739T=DSM 102158T) are proposed, respectively.,
