概要。从有孔虫 Archaias angulatus 中分离出一种共生藻类。来自压碎宿主的藻类呈球状且高度空泡；信封内的分裂阶段很常见。双鞭毛运动梨状生物在新转移的培养物中占主导地位，并逐渐被球状、高度空泡阶段所取代。对于在光下饲养和孵化的生物体来说，完整的古恰亚斯中 14C 标签的掺入效果最好。在光下培养的饥饿共生生物体所吸收的标记量是喂食的共生生物体的 30%，喂食和饥饿的生物体之间 45Ca 的掺入量没有明显差异。光照下钙化明显增强。 Archaias 共生体感染了 Rosalina leei，但没有感染 Quinqueloculina spp。
SYNOPSIS. A symbiotic alga from the foraminifer Archaias angulatus was isolated axenically. Algae from crushed hosts were coccoid and highly vacuolated; division stages within an envelope were common. Biflagellate motile piriform organisms predominated in newly transferred cultures and were gradually replaced by the coccoid, highly vacuolated stage. Incorporation of 14C label in intact Archaias was greatest for organisms fed and incubated in light. Starved symbiotized organisms incubated in the light incorporated ∼30% as much label as fed counterparts, There was no obvious difference in 45Ca incorporation between fed and starved organisms. Light significantly enhanced calcification. The Archaias symbiont infected Rosalina leei but not Quinqueloculina spp.
