嗜硫珠菌属（英語："Thiomargarita"）是硫发菌科的一个属，包括液泡硫细菌——纳米比亚嗜硫珠菌、Candidatus Thiomargarita nelsonii和Ca. Thiomargarita joergensii。^[4] 2022年，科学家在加勒比海紅樹林發現了該屬的一種極其巨大的細菌，命名為华丽硫珠菌，其细胞肉眼可见，可达2 cm。^[5]

该属可在富含硫化氢的环境，诸如冷泉、泥火山、盐水池和富含有机物的沉积物、以及在本格拉洋流和秘鲁凉流下發現的沉積物中找到。這些細菌通常歸類為化能营养生物，它們生存的海水環境，含有週期性上升洋流帶來的大量硝酸鹽。它們利用还原无机硫化物，以此为呼吸作用的电子供体来产生将碳固定成生物质能量，並把富餘的硝酸鹽留存在體內的液泡中。碳固定通过卡尔文循环和可逆克雷布斯循环发生。^[6]當缺乏硝酸鹽時，它們會動用體內的庫存。^[7]
