sp. nov. (Bacillariophyta), a new marine monoraphid diatom species from the coast of Guangxi, China.

A new marine monoraphid diatom species, , is described from the coast of Guangxi, China. The detailed morphology of this epipsammic diatom is studied by using both light and scanning electron microscopy. differs from congeners by a combination of morphological features including capitate apices, multiseriate striae, a small central area on the raphe valve and an oblong sinus on the rapheless valve.

Two new diatom species of the genus (Bacillariophyceae) from the coast of China and two new combinations for the genus.

Two new diatom species belonging to the genus are described, and These two species were compared in detail with congeners. is distinguished by its high stria density and small size. This species was found so far to be epiphytic only on the eelgrass collected from Qingdao Bay (Yellow Sea).

sp. nov., an algicidal bacterium isolated from seawater.

A taxonomic study was carried out on strain BGMRC 0090, which was isolated from seawater. The isolate was a Gram-negative, aerobic, flagellated, rod-shaped bacterium with algicidal activity. Optimal growth was observed at 30 °C, pH 6.

[Phytoplankton pigment patterns and community structure in the Yangtze Estuary and its adjacent areas].

Three cruises were carried out in the Yangtze Estuary and its adjacent areas in May, November, June during 2009-2010. The spatial variations of phytoplankton community structure were investigated based on RP-HPLC analysis of pigments and CHEMTAX processing of the pigment data. 21 kinds of pigments were detected, among which chlorophyll a, peridinin, fucoxanthin, 19'-butanoyloxyfucoxanthin, 19'-hexanoyloxyfucoxanthin, chlorophyll b, diadinoxanthin, alloxanthin and zeaxanthin were the major pigments in the Yangtze Estuary and its adjacent areas.
