Biological characteristics of marine bacterium S-9801 strain and its culture conditions of pigment production

Strain of Flavobacterium sp.(S-9801),was screened from 207 strains of marine bacteria isolated from the Bohai Sea continental shelf and the Zhujiang Estuary,for its red pigment production.The biological characteristics of strain S-9801 and culture conditions of pigment production have been checked out in this study. The color of the bacterial colony on 2216E medium was from coccineus to rose bengal. Optimum culture conditions were sodium chloride concentration(g/dm3),10～30;pH,3～8;temperature,25～28℃;tryptone and yeast extract as nitrogen sources and glucose as carbon source. Under optimum conditions,pigment accumulation started after 12 h,reaching a maximum rate of synthesis at 36 h.

An Analysis on the Influence of Marine Culture and Marine Ecological Environment Protection: Based on the Research Data of St. John's Island

The discovery,protection,and publicity of the marine cultural image will not only affect the economic benefits,but also affect the environmental planning decisions made by the government and have a major impact on marine ecological environmental protection.This article is based on the analysis of the marine cultural protection,ecological environment protection and tourists'relative willingness for environmental consumption on St.John's Island in Singapore.The author discovers that tourists'environmental consumption willingness for St.John's Island includes three different types:cultural environment,ecological environment,and economic convenience environment.From the perspective of the island's cultural cognition,due to insufficient cultural protection awareness and the influence of the surrounding island cultures,tourists have insufficient cognition and cognitive deviations on the historical and ecological culture of St.John's Island,which cannot promote the government planning decision making that are conducive to the island's cultural dissemination and ecological protection.This article uses the CVM method to further propose relevant countermeasures for establishing an accessible ecological protection zone from the perspective of the mechanism of marine culture's impact on marine ecological environmental protection,in order to look forward to promoting the government to make planning decisions that are more conducive to the symbiotic development of marine culture and marine ecological environment through the cultivation and establishment of marine cultural awareness.

ELECTRON MICROSCOPE EVIDENCE OF VIRUS INFECTION IN CULTURED MARINE FISH

Electron microscope investigation on the red sea bream ( Pagrosomus major ), bastard halibut ( Paralichthys olivaceus ) and stone flounder ( Kareius bicoloratus ) in North China revealed virus infection in the bodies of the dead and diseased fish. These viruses included the lymphocystis disease virus (LDV), parvovirus, globular virus, and a kind of baculavirus which was not discovered and reported before and is now tentatively named baculavirus of stone flounder ( Kareius bicoloratus ).

Study on Construction of Marine Culture and Marine Power

Through the development of marine culture to enhance the national cultural soft power, speed up the construction of marine power, has become a strategic choice for the future development of the ocean in China. Based on elaboration on the connotations of the marine culture and marine power, we respectively analyze the relationship between marine culture and marine power construction from the relationships between marine culture and development level of the marine economy, development level of the marine science and technology, the protection ability of the marine environment, international competitiveness of the marine industry, regulation and management of marine affairs and maritime national defense abili- ty. We put forward the countermeasures and suggestions of marine power construction, such as strengthening marine culture propaganda, vigorously developing marine power industry, enhancing the marine cultural safety construction and adhering to development mode of the marine culture with Chinese characteristics.

Marine Ecological Civilization Construction Based on Marine Ecological Culture

Marine ecological civilization is an important part of the socialist ecological civilization, and marine ecological civilization construction is the fundamental way to realize the sustainable development of coastal economy and society. Moreover, it has great theoretical and practical signifi- cance. In this paper, from the perspective of marine ecological culture, the important significance of building marine ecological civilization was ex- plored, and the problems existing in marine ecological civilization construction were analyzed from four aspects of management system, marine in- dustry, ecological action and marine culture. According to the problems, a series of measures to build marine ecological civilization were put for- ward, such as improving marine management system, optimizing marine industrial structure, strengthening infrastructure construction in coastal are- as, and speeding up the development of marine cultural creative industries.

Shanghai sand junk culture and marine culture were introduced from the four aspects of culture(physics,institution,behavior and mentality),and their relation was analyzed.The results show that there is a generic relationship between marine culture and Shanghai sand junk culture.Shanghai sand junk culture reflects the marine culture in a specific period and enriches the connotation of marine culture.Marine culture is the foundation of Shanghai sand junk culture,and provides new opportunities for the sustainable development of Shanghai sand junk culture.Therefore,the study of the relationship between Shanghai sand junk culture and marine culture is beneficial for the two to promote each other,and lays a solid cultural foundation for the realization of"maritime power".

Bacterial diversity in Arctic marine sediment determined by culture-dependent and-independent approaches

Bacterial diversity in surface sediment from the Arctic Ocean was investigated by culture-dependent and-independent approaches. Conventional culture-dependent techniques revealed 11 strains based on their distinct morphological characteristics on marine Zobell 2216E agar plates. Phylogenetic analysis showed that these isolates belonged to three major lineages of the Bacteria,γ-proteobacteria, Bacteroidetes and Actinobacteria, and that they included 10 genera. Most isolates were psychrotrophic, and NaCl was not necessary for their growth. Furthermore, they exhibited activity of at least one extracellular hydrolytic enzyme at 4＆#176;C and had various abilities to assimilate carbon sources. A total of 67 phylotypes were detected among 142 clones based on the 16S rRNA library of the total community DNA and grouped into nine major lineages of bacteria. Phylotypes afifliated withγ-,δ-andε-proteobacteria accounted for 36.7%, 21.8%and 16.9%of the total clones, respectively. The rest of the clones belonged to Bacteroidetes,α-proteobacteria, Actinobacteria, Fusobacteria, Nitrospirae and an unclassiifed group.

Enrichment culture of marine anaerobic ammonium oxidation(anammox) bacteria

The present study investigates the enrichment of anaerobic ammonium oxidation(anammox)bacteria in the marine environment using sediment samples obtained from the East China Sea and discusses the nitrogen removal efficiency of marine anammox bioreactor.Enrichment of anammox bacteria with simultaneous removal of nitrite and ammonium ions was observed in the Anaerobic Sequencing Batch Reactor under a total nitrogen loading rate of 0.37kg-N m-3day-1.In this study,The nitrogen removal efficiency was up to 80%and the molar-reaction ratio of ammonium,nitrite and nitrate was 1.0:1.22:0.22 which was a little different from a previously reported ratio of 1.0:1.32:0.26 in a freshwater system.
