Tree-Ring Dating of the Reshui-1 Tomb in Dulan County, Qinghai Province, North-West China

The actinobacterial strain YIM 70185T was isolated from a saline soil sample collected from Qinghai province, north-west China, and subjected to a taxonomic investigation. Phylogenetic analysis based on 16S rRNA gene sequences revealed 93.5–96.4 % similarity to members of related genera in the family Micrococcaceae. In the phylogenetic dendrogram based on 16S rRNA gene sequence analysis, strain YIM 70185T formed a separate clade next to the genera Micrococcus and Citricoccus within the family Micrococcaceae. The peptidoglycan type was A4α, l-lys–l-ala–l-Glu. Cell-wall sugars contained glucose and tyvelose. The polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol, an unknown phospholipid and an unknown glycolipid. The menaquinones were MK-9, MK-10 and MK-8 (molar ratio 5 : 2 : 1). The major fatty acids were ai-C15 : 0 and i-C15 : 0 and the DNA G+C content was 66.5 mol%. These chemotaxonomic profiles supported the assignment of strain YIM 70185T to a novel genus within the family Micrococcaceae. The name Zhihengliuella halotolerans gen. nov., sp. nov. is proposed. The type strain of Zhihengliuella halotolerans is YIM 70185T (=DSM 17364T=KCTC 19085T).

Diamino Acid

A Gram-positive, aerobic, non-motile actinobacterium, designated strain 6014T, was isolated from a soil sample collected from Qinghai province, north-west China, and subjected to a polyphasic taxonomic study. The isolate formed elementary branching hyphae and abundant aerial mycelia with globose sporangia on ISP 4 and R2A media. Whole-cell hydrolysates of strain 6014T contained arabinose, galactose and ribose as diagnostic sugars and meso-diaminopimelic acid as the diagnostic diamino acid. The polar lipids consisted of phosphatidylmethylethanolamine, phosphatidylethanolamine, hydroxy-phosphatidylethanolamine, N-acetylglucosamine-containing phospholipids, two unknown phospholipids and an unknown glycolipid. The menaquinone system contained MK-9(H2) and MK-9(H4). The major fatty acids were C14 : 0, i-C15 : 0, C16 : 0 and 10-methyl-C16 : 1. The genomic DNA G+C content of the isolate was 69.4 mol%. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain 6014T fell within the radius of the suborder Streptosporangineae, in which the strain formed a distinct lineage next to genera of the family Streptosporangiaceae. Based on data from this polyphasic study, strain 6014T can be readily distinguished from previously described organisms and represents a member of a novel species within a new genus in the suborder Streptosporangineae. The name Sinosporangium album gen. nov., sp. nov. is proposed with 6014T (=DSM 45181T =KCTC 19655T) as the type strain.

A Gram-positive, non-motile actinobacterium, designated strain YIM 70177T, was isolated from a saline soil sample from Qinghai Province, north-west China. Phylogenetic analysis of this organism based on 16S rRNA gene sequences revealed 98·3 % similarity to Isoptericola variabilis DSM 10177T. Chemotaxonomic data determined for the isolate, such as the peptidoglycan type A4α, variation l-lys–d-Asp, supported the placement of strain YIM 70177T within the genus Isoptericola. Galactose was detected as cell wall sugar. Phospholipids identified were phosphatidylinositol, phosphatidylglycerol and diphosphatidylglycerol, and the predominant menaquinones were MK-9(H4) and MK-9(H2). The major fatty acids were ai-C15 : 0, C16 : 0, ai-C17 : 0 and i-C15 : 0. The DNA G+C content was 72·8 mol%. The low level of DNA–DNA relatedness (27·4 %) to I. variabilis DSM 10177T in combination with differentiating chemotaxonomic and physiological data demonstrated that the isolate YIM 70177T should be classified as representing a novel species of the genus Isoptericola. The name Isoptericola halotolerans sp. nov. is proposed, with strain YIM 70177T (=DSM 16376T=KCTC 19046T) as the type strain.

The first TBE patients in China were reported in 1943, and the TBEV was isolated from the brain tissues of 2 patients in 1944 by Japanese military scientists,1 and from patients and ticks (Ixodes persulcatus and Haemaphysalis concinna) in 1952 by Chinese researchers.2 The Far Eastern viral subtype (TBEV-FE) is the endemic subtype that has been isolated from all 3 known natural foci (northeastern China, western China, and southwestern China).14 Recently a new “Himalayan subtype” of the TBEV (TBEV-HIM) was isolated from wild rodent Marmoata himalayana in the Qinghai-Tibet Plateau15. The main vector of the TBEV in China is I. persulcatus.3 One recent report suggests that the TBEV-SIB is prevalent in the Uygur region (North West China)13 but epidemiological modelling indicates that the TBEV may occur even widely all over China (Figure 3).4 Likely, the disease is often missed by clinicians due to a lack of the availability of specific diagnostic assays16.

Storage Facilities

The British Library’s Stein collection contains about 14,000 scrolls, fragments and booklets in Chinese from a cave in the Buddhist Mogao Caves complex near Dunhuang in north-west China. This article describes storage and access solutions for the collection in the context of a busy research library and the currently ongoing Lotus Sutra Manuscripts Digitisation project. The article presents the various technical and organisational challenges that its rehousing presents to the library conservators. Restricted by the existing storage facilities, budget limitations and tight project deadlines, the conservators must provide housing that is adequate for the scroll format, is practical and prevents dissociation, but is also cost- and time-effective. With the best storage practice in mind, they have developed original solutions, balancing the specific housing requirements and constraints. These storage solutions allow the conservators to ensure the long-term safety and accessibility of the collection while laying down a foundation of standardisation that will ensure a homogeneity of approaches for future projects.
