培养30天后，培养液中有大量休眠孢囊，将藻液避光保存90天后，观察到培养基中有4种类型的休眠孢囊产生：(1)球形到椭球形(长25-39 μm)，钙质外壁，稀疏或密被钙质附属物(长1-4 μm)；(2)球形(直径为29-35 μm)，钙质外壁，附属物非钙质(长0.5-1.5 μm)；(3)球形到椭球形(长29-35 μm)，钙质，表面光滑，无附属物；(4)球形(直径24-35 μm )，有机外壁，无附属物。

Calcareous tufa, a porous or spongy deposit of calcium carbonate found in calcareous mineral springs.

多孔状凝灰岩石灰质的凝灰岩，碳酸钙多孔或有吸收性的沉淀物，出现在''。

Be rich in various foodstuffs such as calcareous and VD3 , help effective against the calcareous sorption of cat , boost healthiness and strongness of cat skeleton growing up , avoid the osteoporosis arousing because long range liver kind food is used for food.

A soft, pure, earthy, fine-textured, usually white to light gray or buff limestone of marine origin, consisting almost wholly (90-99%) of calcite, formed mainly by shallowwater accumulation of calcareous tests of floating microorganisms and of comminuted remains of calcareous algae (such as cocoliths and rhabdoliths), set in a structureless matrix of very finely crystalline calcite.

中文解释=海产起源的石灰石，柔软、纯净、土质、组织精细，通常从白色到浅灰或浅黄色，几乎完全（90-99％）由方解石组成，主要由浮游微生物的粉碎残留物浅水堆积而成，嵌在非常精细的方解石晶体的无定形填质中。

From the development of the Carboniferous reefs, the metazoan framework reefs and the reefs dominated by microbes and calcareous algae may be two parallelling evolution reef ecosystems. The development of the metazoan framework reefs after the extinction event reflects an obvious evolutionary lag time. The recovery of the reef-building communities dominated by microbes and calcareous algae became faster after the extinction event.

从石炭纪整个生物礁的发展情况来看，后生动物骨架礁与以微生物和钙藻为主导的生物礁或许是两个平行发展的礁系统，后生动物骨架礁的发展在大规模生物灭绝事件之后有明显的演化滞后现象，以钙藻和微生物为主导的造礁群落的复苏在生物灭绝事件之后更为迅速。
