Isolation and Cultivation of Zooxanthellae
Nature, 1957A REMARKABLE characteristic of tropical coral reefs, and indeed to some extent of shallow marine waters everywhere, is the profusion of single-cell, yellow-green algae (the so-called symbiotic zooxanthellae) that live within a wide variety of radiolarians, cœlenterates, molluscs, bryozoans, worms, ascidians, etc.

Marine Biology, 1984
Pocillopora damicornis (Linnaeus) and Montipora verrucosa (Lamarck) were collected from Hawaiian reefs. In two experiments (September 1979-January 1980: ca. 4 mo; August-October 1980; ca. 2 mo), these reef corals were grown under sunlight passed through filters producing light fields of similar quantum flux but different spectral composition.

Photosynthetic carbon dioxide fixation in zooxanthellae
Marine Biology, 1993The carbon-fixation patterns of freshly isolated zooxanthellae from the hermatypic coral Acropora formosa were examined during a 15 min exposure to sodium mosa were examined during a 15 min exposure to sodium [14C]bicarbonate. The labelling pattern during the first 60 s exposure showed that the C3 carbon-fixation pathway is the major route for ...

Sulfur assimilation in corals with aposymbiotic and symbiotic zooxanthellae
Environmental Microbiology Reports, 2020Summary Although sulfate ions are the main form of sulfur in the ocean, there is limited knowledge on their use by living organisms. Stable isotope labelling and NanoSIMS analysis were used in this study to clarify how sulfate, in seawater, is assimilated by corals and zooxanthellae at the cellular level ...

Morula-Like Cells in Photo-Symbiotic Clams Harboring Zooxanthellae
Zoological Science, 1998Symbiosis is observed between zooxanthellae, symbiotic dinoflagellates, and giant clams and related clams which belong to the families Tridacnidae and Cardiidae. We have previously shown that a photo-symbiotic clam Tridacna crocea has three types of hemocytes, the eosinophilic granular hemocyte with phagocytic activity, the agranular cell with electron

Mode of zooxanthella transmission does not affect zooxanthella diversity in acroporid corals
Marine Biology, 2003Two distinct modes of algal endosymbiont acquisition exist in corals, a direct transmission from the parental colony to the eggs and a larval or post-larval uptake from the environment. The former, maternal-transmission mode is expected to be a more closed system, while the latter is believed to be an open system.

Nutrient uptake kinetics of freshly isolated zooxanthellae
Marine Biology, 1983Zooxanthellae of the species Gymnodinium (=Symbiodinium) microadriaticum freshly isolated from a variety of hosts (Zoanthus spp., Tridacna crocea, Seriatopora hystrix, Montastrea annularis, Porites furcata, and Stylophora pistillata) in the tropical Pacific Ocean and the Caribbean Sea exhibited saturation uptake kinetics when incubated in seawater ...

Zooxanthellae are photosynthetic unicellular marine algae endosymbiotic with marine invertebrates. The term is a vernacular derivation of the original genus Zooxantheila, coined by Brandt (1) to describe the dinoflagellate symbionts of the radiolarian Collozoum inerme Haeckel, but now used to describe almost any yellow-brown unicellular algal symbiont.

การแยกและเลี้ยง zooxanthellae สายพันธุ์ทนร้อนจากปะการังและหอยสองฝา : รายงานผลการดำเนินงาน
2014อุณหภูมิที่เพิ่มขึ้นและความเค็มที่ลดลงเป็นสาเหตุสำคัญที่ทำให้เกิดปรากฏการณ์ฟอกขาวในปะการังและสัตว์ทะเลไม่มีกระดูกสันหลัง เพื่อให้ทราบผลของปัจจัยดังกล่าว จึงได้ทำการศึกษาความทนทานต่ออุณหภูมิและความเค็มใน zooxanthellae ที่แยกจาก ปะการังดอกกะหล่ำ (Pocillopora damicornis), ปะการังดอกเห็ด (Fungia sp.) และ ดอกไม้ทะเล (Epiactis sp.) โดยทำการแยกเลี้ยงเซลล ...
