种牡蛎

The results show that the optimal hydrolysis conditions of these three enzymes were:50℃,pH 8.5, substrate concentration 1:3,enzyme dosage 1200U/g,time 4h for Alcalase; 45℃,pH 8.1, substrate concentration 1:3, enzyme dosage 1200U/g, time 4h for Trypsin;50℃, pH5.5, substrate concentration 1:3, enzyme dosage 1400U/g, time 6h for Bromelin, respectively. The compound enzymes hydrolysis was investigated on the basis of the single enzyme hydrolysis.

利用单因素试验和正交试验分别对这三种酶单独水解牡蛎的条件进行了研究，得出三种酶水解牡蛎的最佳条件分别为Alcalase：温度50℃，pH8.5，料水比1：3，加酶量1200U/g，时间4h；胰蛋白酶：温度45℃，pH8.1，料水比1：3，加酶量1200U/g，时间4h；菠萝蛋白酶：温度50℃，pH5.5，料水比1：3，加酶量1400U/g，时间6h；为牡蛎生物活性肽的开发提供了基础参考数据。

The paper summarized the major research progress on taxonomic and molecular biology studies of Jinjiang oyster. The synthesis results show: The Jinjiang oyster is a hybrid of 3 species including "red oyster" not yet be named and "white oyster", which include Hong Kong cultured oyster. Crassosstrea hongkongensis and Suminoe oyster C.ariakensis .

文章综述了近江牡蛎分类研究进展，综合有关研究报道认为华南沿海养殖的近江牡蛎可能是3个物种的混合体："赤蚝"可能是一个新种，而"白蚝"含有香港巨牡蛎和有明巨牡蛎2个物种。

It is necessary to use the molecule mark to clarify taxonomic status of these species.

由于这些争议的存在，有必要采用分子标记对这几种牡蛎进行区分与鉴定。

Were used; for filter-eeding experiment, the alga used was Nitzschia closterium, and the experimental temperatures were 20, 23, 26, 29℃.Results show that the feeding selectivity of small-ized bay scallop and the oyster increase with algae size:when the algae increased from 4.35m to 11.6m, the feeding rate of bay scallop increased from 4.21%to 11.0%and that of the Pacific oyster from 0.81%to 3.15%.

结果表明，海湾扇贝和太平洋牡蛎的小贝的摄食率随藻类规格的增大而增加；而大贝则表现出明显的差异，海湾扇贝对中等规格（＝5.55—5.79m）的藻类、太平洋牡蛎对小规格（＝4.35m）的藻类具有较高的选择性，表明相同条件下两种贝类对海洋浮游植物群落结构产生不同的影响。

Reciprocal diallel cross was conducted to confirm the hybrid possibility of the two oysters.

结果表明，两种牡蛎不存在明显的生态隔离和季节隔离等交配前生殖隔离机制。

There is a case of an oysterlike bivalve that evolved a more and more spiraled shell until, just before extinction, the valves could barely open.

这里有个例子，一种牡蛎状双壳类，进化出越来越趋螺旋状的外壳，直到该物种灭绝，其外壳已几乎不能打开。

There is a case of an oysterlike bivalve that evolved a more and more spiraled shell until, just before extinction, the valves could barely open.

这里有个例子，一种牡蛎状双壳贝，进化出越来越趋螺旋状的外壳，直到该物种灭绝前，其外壳已经几乎打不开了。

There is a case of an oysterlike bivalve that evolved a more and more spiraled shell until, just before extinction, the valves could barely open.

这里有个例子，一种牡蛎状双壳类软体动物，进化出越来越趋螺旋状的外壳，这种进化直到该物种灭绝前未停止过，其外壳已几乎不能开合。

It has been presumed that there are four common Crassostrea oyster species along the coast of China: the Crassostrea gigas, C.

长期以来人们一直认为我国有四种具有经济意义的牡蛎：太平洋牡蛎、褶牡蛎C。

Intre-species genetic diatance of four species of oyster shows the divergence between C. gigas and C.

种间的遗传距离表明：太平洋牡蛎和大连湾牡蛎为0.2818，褶牡蛎和近江牡蛎为0.1011甚至小于种内的距离(0.1273和0.1251)。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
