Cellulosic biofuels represent a powerful alternative to petroleum but are currently limited by the inefficiencies of the conversion process. While gram-positive and fungal organisms have been widely explored as sources of cellulases and hemicellulases for biomass degradation, gram-negative organisms have received less experimental attention. We investigated the ability of Cellvibrio japonicus, ...

Ochlerotatus japonicus larvae were collected from natural rockpools in New Jersey within the Delaware Water Gap National Recreational Area. Previously reported collections of Oc. japonicus in the United States have been limited to artificial containers and an occasional treehole.

We investigated in this study the anti-obesity effect of an extract of Petasites japonicus (a culinary vegetable from Eastern Asia) on a murine adipocyte cell line (3T3-L1) and on diet-induced obesity-prone mice. An ethanol extract of P. japonicus. (PJET) suppressed 3T3-L1 preadipocyte differentiation; however, a hot water extract of P. japonicus (PJHW) exhibited no effect on cell differentiati...

The two-component systems (TCS), or histidine-to-aspartate phosphorelays, are evolutionarily conserved common signal transduction mechanisms that are implicated in a wide variety of cellular responses to environmental stimuli in both prokaryotes and eukaryotes including plants. Among higher plants, legumes including Lotus japonicus have a unique ability to engage in beneficial symbiosis with ni...

The root of Ophiopogon japonicus has been used as a traditional Chinese medicine and also a functional food ingredient for a long time in China. In the present study, 17 different homoisoflavonoid compounds were identified in the root extract of O. japonicus by HPLC–DAD and LCMS/MS analyses. The antioxidant activity of the of chloroform/methanol (1:1, v/v), methanol and 70% ethanol extracts, an...

Hans U. Dahms, Supawadee Chullasorn, Pawana Kangtia, Frank D. Ferrari, and Jiang-Shiou Hwang (2007) Naupliar development of Tigriopus japonicus Mori, 1932 (Copepoda: Harpacticidae). Zoological Studies 46(6): 746-759. Six naupliar stages of Tigriopus japonicus Mori, 1932 are described from the rocky coast off Keelung, northeastern Taiwan. A key for the identification of stages is provided. Naupl...

Recent phylogenetic studies using mtDNA and allozymes clarified the presence of multiple distinct genetic lineages in the Japanese clawed salamander, Onychodactylus japonicus, of which two from northern regions of the country have already been described as new species. Based on morphological analyses of the remaining genetic lineages, we describe the lineage from Shikoku Island and Chugoku Moun...

The Panax genus has been a source of natural medicine, benefitting human health over the ages, among which the Panax japonicus represents an important species. Our understanding of several key pathways and enzymes involved in the biosynthesis of ginsenosides, a pharmacologically active class of metabolites and a major chemical constituents of the rhizome extracts from the Panax species, are lim...
