Abstract—

The substances contained in the aqueous–ethanol and aqueous extracts from freshly collected and destroyed brown algae Saccharina cichorioides in their second vegetation season and from excrement of the sea urchins Strongylocentrotus intermedius that had been fed these algae specimens were studied for effects on the digestive enzyme 1,3-β-D-glucanase, sperm, egg cells, and developing embryos of the sea urchin. The yield, composition, and structure of substances from fresh and destroyed S. cichorioides and from sea urchin excrement were analyzed. Sea urchins assimilated mannitol, proteins, and almost completely laminarans from destroyed thalli of S. cichorioides. The detection of activators of sea urchin 1,3-β-D-glucanase in the aqueous–ethanol extracts of destroyed algae and inhibitors of fertilization processes in the extracts of fresh algae is consistent with field observations. The biochemical study has shown that the digestion and reproduction processes in S. intermedius are controlled by metabolites of S. cichorioides to a significant extent.

褐藻糖藻（Miyabe）的代谢产物对海胆Strongylocentrotus intermedius A. Agassiz，1863年的摄食习性，受精和胚胎发育的影响

摘要—

研究了在第二个植被季节新鲜收集和销毁的褐藻Saccharina cichorioides的水-乙醇和水提取物中所含的物质以及饲喂这些藻标本的海胆Strongylocentrotus intermedius的排泄物对消化酶的影响1 ，3-β-D-葡聚糖酶，精子，卵细胞和海胆发育中的胚胎。分析了来自新鲜和破坏的链球菌和海胆排泄物的物质的产量，组成和结构。海胆从被破坏的S. cichorioides的thalli中吸收了甘露醇，蛋白质和几乎完全的薄片。在被破坏的藻类的水-乙醇提取物中检测海胆1,3-β-D-葡聚糖酶的活化剂以及在新鲜藻类提取物中检测受精过程的抑制剂与现场观察一致。生化研究表明，中间链球菌的消化和繁殖过程在很大程度上受环孢链球菌代谢产物的控制。
