A Bacillus subtilis strain was isolated from the intestine of Sebastiscus marmoratus (scorpion fish) that was identified as Bacillus subtilis CH2 by morphological, biochemical, and genetic analyses. The chitosanase of Bacillus subtilis CH2 was best induced by fructose and not induced with chitosan, unlike other chitosanases. The strain was incubated in LB… (More)
Ultraviolet-B (UV-B) irradiation has been known to generate oxidative stress by increasing reactive oxygen species (ROS) in skin cells. Several naturally occurring antioxidant compounds isolated from marine algae are believed to protect against ROS. In this study, we assessed the antioxidative effect of eckstolonol isolated from Ecklonia cava against… (More)
In this study, the anti-inflammatory effect of fucoxanthin (FX) derivatives, which was isolated from Sargassum siliquastrum were evaluated by examining their inhibitory effects on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated murine macrophage RAW 264.7 cells. The FX derivatives were isolated from activity-guided chloroform fraction… (More)
We isolated Mesoflavibacter zeaxanthinifaciens S86 as xylanase-producing bacteria from seawater sampled in Micronesia. Analysis of the M. zeaxanthinifaciens genome revealed that it contains a single circular chromosome of 3,704,661 bp with 3,249 putative open reading frames.
In this study, we isolated xylan-degrading bacteria from a coastal lagoon of Micronesia and identified the bacteria as Marinobacterium stanieri S30. GSFLX 454 pyrosequencing and sequence analysis of the M. stanieri S30 genome generated 4,007 predicted open reading frames (ORFs) that could be candidate genes for producing enzymes with different catalytic… (More)
The coast of the Korean peninsula experiences a range of human impacts, including pollution, shipping, reclamation, and aquaculture, that have motivated numerous local studies of macrobenthic organisms. In this paper, 1,492 subtidal stations were compiled from 23 studies (areas) to evaluate environmental quality on a broader scale. A common index in… (More)
We report here the annotated genome sequence of the marine bacterium Alteromonas sp. S89 and the identification of six genes coding for agar-degrading enzymes. The sequenced Alteromonas sp. S89 genome is composed of a 3,864,871-bp circular chromosome that includes 3,236 complete open reading frames.
The damselfish (Pomacentridae) is a major component of reef fish assemblages, inhabiting shallow reef areas in tropical and subtropical areas (Allen 1991; Frédérich et al. 2009). This family represents the greatest diversity and abundance of fish species inhabiting coral reefs (Meekan et al. 1995). Many pomacentrid species are intensely territorial and… (More)
