Abstract

A novel halovirus, VOLN27B, was isolated from a drill core sample taken at a depth of approximately 430 m, from a layer formed during the Cretaceous period (Anhui, China). VOLN27B infects the halophilic archaeon Halorubrum sp. LN27 and has a head-tailed morphotype with a contractile tail, typical of myoviruses. The average head diameter is 64 ± 2.0 nm, and uncontracted tails are 15 ± 1.0 × 65 ± 2.0 nm. The latent period is about 10 h. The maturing time of VOLN27B in cells of Halorubrum sp. LN27 was nearly 8 h. The adsorption time of VOLN27B on cells of Halorubrum sp. LN27 was less than 1 min. Virus particles are unstable at pH values less than 5 or when the NaCl concentration is below 12% (w/v). VOLN27B and Halorubrum sp. LN27 were recovered from the same hypersaline environment and provide a new virus-host system in haloarchaea.

从地下盐晶体中分离出一种新的头尾盐病毒并感染盐丛。

在白垩纪时期(中国安徽)形成的地层中，从深度约430 m的岩心样本中分离出一种新的halovirus, VOLN27B。VOLN27B感染嗜盐古菌Halorubrum sp. LN27，具有典型的肌病毒的头尾形态，尾部可收缩。平均头径64±2.0 nm，未收缩尾径15±1.0 × 65±2.0 nm。潜伏期约10小时。VOLN27B在Halorubrum sp. LN27细胞中的成熟时间接近8 h。VOLN27B在Halorubrum sp. LN27细胞上的吸附时间小于1 min。当pH值小于5或NaCl浓度低于12% (w/v)时，病毒颗粒不稳定。VOLN27B和Halorubrum sp. LN27是从相同的高盐环境中分离出来的，在盐古菌中提供了一种新的病毒宿主系统。

期刊介绍： Archaea is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles dealing with all aspects of archaea, including environmental adaptation, enzymology, genetics and genomics, metabolism, molecular biology, molecular ecology, phylogeny, and ultrastructure. Bioinformatics studies and biotechnological implications of archaea will be considered. Published since 2002, Archaea provides a unique venue for exchanging information about these extraordinary prokaryotes.
