A yellow-pigmented bacterial strain, designated LL01T, was isolated from hexachlorocyclohexane (HCH)-contaminated soil at Spolana Neratovice, a former Czech producer of lindane. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL01T occupied a distinct phylogenetic position in the Sphingobium cluster, showing highest similarity to Sphingobium rhizovicinum CC-FH12-1T (98.5 %). The DNA G+C content of strain LL01T was 66.1 mol%. The predominant respiratory pigment was ubiquinone Q-10. The polar lipid profile of strain LL01T also corresponded to those reported for other Sphingobium species (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, sphingoglycolipids), supporting its identification as a member of the genus Sphingobium . Spermidine was the major polyamine observed. The results obtained from DNA–DNA hybridization and biochemical and physiological tests clearly distinguished strain LL01T from closely related species of the genus Sphingobium . Therefore, strain LL01T represents a novel species of the genus Sphingobium , for which the name Sphingobium czechense sp. nov. is proposed (type strain LL01T = CCM 7979T = DSM 25410T).

A Gram-stain-positive, novel actinobacterium, designated strain JL-6T, was isolated from the litter of a bamboo (Sasa borealis) forest in Damyang, Korea. Strain JL-6T had white‐grey, smooth, cylindrical spores that were borne in straight, long spore-chains. The novel strain grew aerobically at 15–28 °C (optimum, 28 °C), pH 4.0–8.0 (optimum, pH 5.5) and with 0–1.5 % (w/v) NaCl. The cell-wall peptidoglycan contained ll-diaminopimelic acid, glutamic acid, alanine and glycine. The predominant menaquinones were MK-9(H6) and MK-9(H8). Whole-cell hydrolysates mainly contained glucose and ribose. Phosphatidylinositol and phosphatidylcholine were the diagnostic phospholipids. The G+C content of the genomic DNA was 72.8 mol%. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain JL-6T belonged to the genus Streptomyces with sequence similarities ranging from 97.3 % to 98.3 %. However, DNA–DNA hybridization between JL-6T and the closest related strain, Streptomyces turgidiscabies , ATCC 700248T and other closely related species in the genus Streptomyces showed <50 % relatedness. Based on these observations, strain JL-6T is proposed to represent a novel species of the genus Streptomyces , for which the name Streptomyces graminilatus sp. nov. is proposed. The type strain is JL-6T ( = KACC 16470T = NBRC 108882T).

A Gram-stain-negative, rod-shaped and white-coloured bacterial strain, designated LL03T, was isolated from hexachlorocyclohexane-contaminated soil at Spolana Neratovice, Czech Republic, where lindane was formerly produced. Strain LL03T was found to be a degrader of α-, γ- and δ-isomers of hexachlorocyclohexane, although no significant degradation activity was observed for the β-isomer. A neighbour-joining tree based on 16S rRNA gene sequences showed that strain LL03T occupied a distinct phylogenetic position in the Sphingobium cluster, showing the highest similarity with Sphingobium wenxiniae JZ-1T (99.2 %). The DNA G+C content of strain LL03T was 67.0 mol%. DNA–DNA relatedness values of strain LL03T with its close phylogenetic neighbours were below the threshold level of 70 %, supporting its identification as a representative of a novel species of the genus Sphingobium . The predominant respiratory quinone was ubiquinone Q-10. The polar lipid profile of strain LL03T also corresponded to those reported for other Sphingobium species (phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and sphingoglycolipid), supporting its identification as a member of the genus Sphingobium . Spermidine was identified as the major polyamine. The predominant fatty acids were 16 : 0, summed feature 3 (16 : 1ω7c and/or 16 : 1ω6c), summed feature 8 (18 : 1ω7c and/or 18 : 1ω6c) and 14 : 0 2-OH. The polar lipid pattern, the presence of spermidine and ubiquinone Q-10, the predominance of the cellular fatty acids C18 : 1ω7c, C16 : 0 and C14 : 0 2-OH and the G+C content of the genomic DNA supported the affiliation of the strain to the genus Sphingobium . The results obtained after DNA–DNA hybridization, biochemical and physiological tests clearly distinguished it from closely related species of the genus Sphingobium . Therefore, strain LL03T represents a novel species of the genus Sphingobium for which the name Sphingobium baderi LL03T sp. nov. is proposed; the type strain is LL03T ( = CCM 7981T = DSM 25433T).
