“…The wholecell hydrolysate of the isolate contained meso-diaminopimelic acid as the only diamino acid of the peptidoglycan and arabinose and galactose as major cell-wall sugars, which places strain Chol-3 T in cell-wall chemotype IV according to Lechevalier & Lechevalier (1970). The main mycolic acid components of strain Chol-3 T and some Gordonia type strains are listed in Supplementary Table S1 (available in IJSEM Online).…”

“…Cellular fatty acid composition was determined as described by Sasser (1990) using the Microbial Identification System (MIDI, Inc.). Amino acids in the peptidoglycan layer of strain YIM 002 T were LL-A 2 pm, alanine, glycine and glutamic acid, indicating a type I wall chemotype according to the classification of Lechevalier & Lechevalier (1970). Cell-wall sugars were glucose and ribose.…”

A novel actinomycete strain, designated YIM 002T, was isolated from a desert soil sample in Gansu Province, north-west China. This actinomycete isolate formed well-differentiated aerial and substrate mycelia. In the early stages of growth, the substrate mycelia fragmented into short or elongated rods. Chemotaxonomically, it contained ll-2,6-diaminopimelic acid in the cell wall. The cell-wall sugars contained ribose and glucose. Phospholipids present were phosphatidylinositol mannosides, phosphatidylinositol and diphosphatidylglycerol. MK-9(H4) was the predominant menaquinone. The major fatty acids were anteiso C15 : 0 (35·92 %), anteiso C17 : 0 (15·84 %), iso C15 : 0 (10·40 %), iso C16 : 0 (7·07 %) and C17 : 1 ω8c (9·37 %). The G+C content of the DNA was 70 mol%. Phylogenetic analysis and signature nucleotide data based on 16S rRNA gene sequences showed that strain YIM 002T is distinct from all recognized genera of the family Nocardioidaceae in the suborder Propionibacterineae. On the basis of the phenotypic and genotypic characteristics, it is proposed that isolate YIM 002T be classified as a novel species in a new genus, Jiangella gansuensis gen. nov., sp. nov. The type strain is YIM 002T (=DSM 44835T=CCTCC AA 204001T=KCTC 19044T).

“…The cell wall of strain CS5-AC15 T contained mesodiaminopimelic acid as the diagnostic diamino acid and madurose and glucose as whole-cell sugars, showing that it possessed cell-wall type III (Lechevalier & Lechevalier, 1970a) and whole-cell sugar pattern B (Lechevalier, 1968). The acyl type of murein in the peptidoglycan was acetyl.…”

A novel actinomycete strain, designated CS5-AC15 T , was isolated from a soil sample collected from a cliff on Mara Island, Jeju, Republic of Korea, and subjected to a polyphasic taxonomic analysis. The isolate produced well-developed, yellow substrate mycelium and white aerial mycelium that differentiated into straight or flexuous chains of smooth-surfaced spores. 16S rRNA gene sequence analyses showed that the organism belonged to the family Thermomonosporaceae and formed a tight cluster with the type strain of Actinomadura oligospora (97.4 % sequence similarity). Chemotaxonomic characteristics were consistent with its assignment to the genus Actinomadura in that the isolate had meso-diaminopimelic acid as the diagnostic diamino acid in the cell wall, madurose as the characteristic sugar, N-acetyl type of murein in the peptidoglycan, MK-9(H 6 ) and MK-9(H 8 ) as major menaquinones and a polar lipid profile containing diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown phospholipids. Mycolic acids were not detected. The predominant fatty acids were C 16 : 0 , C 18 : 1 v9c and iso-C 16 : 0 . The DNA G+C content was 70.9 mol%. DNA relatedness of strain CS5-AC15 T and A. oligospora JCM 10648 T was 37.9±0.7 %. On the basis of the phenotypic, phylogenetic and DNA-DNA hybridization data, strain CS5-AC15 T is assigned to a novel species of the genus Actinomadura, for which the name Actinomadura rupiterrae sp. nov. is proposed (type strain CS5-AC15 T 5KCTC 19559 T 5DSM 45251 T ).
