Photobacterium ganghwense sp. nov., a halophilic bacterium isolated from sea water

A marine bacterial strain, designated FR1311(T), was isolated from a sea-water sample from Ganghwa. Island, South Korea. Cells were Gram-negative, facultatively anaerobic, catalase- and oxidase-positive, motile, oval or rod-shaped and halophilic, (optimum sea-salt concentration for growth of 5-6%). Phylogenetic analysis of its 16S rRNA gene sequence revealed that it represented a distinct line of descent within the genus Photobacterium. The major fatty acids were straight-chain saturated (C-16:0) and monounsaturated fatty acids (C(16:)1 omega 7c and C-18:1 omega 7c). The predominant respiratory lipoquinone was Q-8. The DNA G + C content was 44 mol%. The phenotypic features of strain FR1199(T) were similar to those of Photobacterium damselae subsp. damselae and Photobacterium damselae subsp. piscicida, but several physiological and chemotaxonomic properties readily distinguish the new isolate from them. On the basis of the polyphasic results revealed in this study, FR1311(T) is considered to be the type strain of a novel species, for which the name Photobacterium ganghwense sp. nov. is proposed. The type strain is FR1311(T) (=IMSNU 60287(T) =KCTC 12328(T)=JCM 12487(T)).

Case Study on the Changes in the Physical Environment in Forest Healing Spaces

This study was conducted to investigate changes in the physical environment in forest healing spaces by examining each of two tree species in a space within the Kasuya Research Forest, Kyushu University. At the study site, culmination and sunset showed high TNVOCs, low concentrations of particulate matter, and low PPD. Of the NVOCs, camphor was detected with the highest concentrations, 0.359 ng/m^3 and 0.142 ng/m^3, in C. camphora and M. thunbergii, respectively. Coniferous trees are generally used when creating an environment for healing purposes, as they are known to emit a large amount of NVOCs. However, according to our results, deciduous trees also emit NVOCs of sufficient concentrations. Therefore, if forest healing spaces are created with the appropriate components, it can have effective results
