Periostracum - Wikipedia
网页The periostracum (/ ˌpɛriˈɒstrəkəm / PERR-ee-OS-trə-kəm) is a thin, organic coating (or "skin") that is the outermost layer of the shell of many shelled animals, including molluscs and brachiopods.
Periostracum | shell structure | Britannica
网页The outer layer, or periostracum, is a mixture of proteins known as conchin. Inner layers of calcium carbonate interlace with a network of conchin and are impregnated with a variety of mineral salts. The calcium usually is in the form of calcite crystals in marine species and aragonite crystals… Read More.
The Mode of Formation and the Structure of the Periostracum
网页1983年1月1日 · The periostracum is formed sequentially as it passes out of the periostracal groove, undergoing tanning and finally a modification of the inner surface allowing calcification to begin. Studies are underway on the chemistry of periostracum formed in vitro and in vivo and on the cellular formation of periostracum in vitro. Previouschapter.
Structure and function of the periostracum in the bivalve
网页2023年6月1日 · The periostracum is an outermost coating of all shelled-molluscs such as bivalves, corresponding to the interfacial layer separating the calcareous shells from the environment. It therefore plays a key role in the growth and survival of bivalves. Nevertheless, the periostracum has attracted little attention.

Antifouling effects of the periostracum on algal spore settlement …
网页2016年3月18日 · Our results, periostracum composition and structure results, suggest that mussel periostraca or their associated biomimetic materials may become environmentally friendly antifouling materials preventing the attachment of diverse fouling organisms.
Early Stage Biomineralization in the Periostracum of the ... - PLOS
网页2014年2月25日 · The present study focuses on the origin and formation of the periostracum in the trigonioid bivalve Neotrigonia, in particular on the morphological and histological study of the development changes of the periostracum from its formation in the periostracal groove to its complete calcification at the shell margin.
Significance of the Structure of the Brachiopod Periostracum
网页Two different types of periostraca have been found in living articulate brachiopods. These two types can be correlated to give some indication of the structure of the prototypic shell.
