鹿角藻目：褐藻门的一个目，其单倍体后代只由配子组成，配子在一个称为生殖窝（通常位于叶状体分支膨大的顶端）的特殊腔中产生。

Epiphytic bacteria were isolated from sporophytic thallus collected from Qingdao and Dalian or gametophytic filaments stored in our lab of Laminaria japonica. Identification was done using both traditional physiological and biochemical way and molecular method. Phylogeny tree was established based on 16S rRNA gene sequence analyses, and some sequences of epiphytic strains from both sporophyte and gametophyte were different from all the sequences already exit and could be the new species.

采用生理生化和16S rRNA基因序列比对的方法对从两个海区采集的海带孢子体以及实验室中保存的海带配子体样品的外生菌分别进行组成分析，16S rRNA基因序列揭示了在海带孢子体和配子体的外生菌中都存在一些与现有数据库中序列的遗传关系较远的菌株。

Nutrient cells were obtained from these pigment mutants by enzymatic method and conchocelis were got by parthenogenesis. When the conchocelis were mature and conchospores were released, they were cultured singly and picked up as F1 gametophytic thallus.

With the depletion of ozone layer in stratosphere, solar UV-B radiation on theearth surface is increasing. Plants use sunlight for photosynthesis, and it is inevitable that they are affected by enhanced UV-B in the sunlight. Effects of UV-B radiation on the morphological structure and physiological biochemistry in leafy thallus of Spirodela polyrhiza were investigated in the present study.

大气臭氧层的耗损导致到达地面的UV-B辐射的增加，植物需要接受太阳光进行光合作用，因而不可避免地受到阳光中增强的UV-B辐射的影响。

The invention uses the fermentation liquor of one Escherichia coli generating polysialic acid as material, filters and removes thallus, adds some solvents as sodium chloride and alcohol into supernatant to deposit polysialic acid, dissolves the polysialic acid deposits via deionized water, filters to remove modified protein, uses alkali prolease to treat filtrate, complexes deposits via cetyl pyridinium chloride or cetyltrimethylammonium bromide, and dissociates, uses over alcohol to deposit polysialic acid, dissolves the deposits via ultra-pure water, grades and purifies via chromatography column, collects and dialyzes eluent, cools and dries to obtain polysialic acid.
