''Kappaphycus'' is a genus of red algae. Species are distributed in the waters of East Africa, Indonesia, Malaysia, Hainan Island, the Philippines, and Micronesia.〔Guiry, M. D. In: Guiry, M. D. & G. M. Guiry. 2013. (''Kappaphycus''. ) AlgaeBase. National University of Ireland, Galway. Accessed 07 November 2013.〕 Genus ''Kappaphycus'' is "morphologically plastic",〔 with few visible characters that can be used to separate the taxa, so distinguishing the species can be difficult. In addition, many commercial varieties have been bred. Molecular analyses can be used.〔Conklin, K. Y., et al. (2009).

C., et al. (2006). (Systematics and genetic variation in commercial ''Kappaphycus'' and ''Eucheuma'' (Solieriaceae, Rhodophyta). ) ''Journal of Applied Phycology'' 18(3-5) 643-51.〕〔Tan, J., et al.

Agardh (Solieriaceae, Rhodophyta). ) PLoS ONE, 7(12), e52905.〕 In general, these algae have fleshy thalli that grow erect from one or more anchors. The longest individuals can exceed a meter in length. All species produce kappa-carrageenan.〔 Farming of this is a large business in the Philippines. Prof. Gavino Cajulao Trono Jr is a Filipino biologist dubbed the “Father of Kappaphycus farming”. ''Kappaphycus alvarezii'' is widely cultivated as a raw source of carrageenan, and other species are used, as well. Several ''Kappaphycus'' are invasive species.〔Conklin, E. J. and J. E. Smith. (2005). (Abundance and spread of the invasive red algae, ''Kappaphycus'' spp., in Kane'ohe Bay, Hawai'i and an experimental assessment of management options. ) ''Biological Invasions'' 7(6), 1029-39.〕 There are about 6 species:〔 *''Kappaphycus alvarezii'' *''Kappaphycus cottonii'' *''Kappaphycus inermis'' *''Kappaphycus malesianus'' *''Kappaphycus procrusteanus'' *''Kappaphycus striatus'' ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kappaphycus」の詳細全文を読む スポンサード リンク
