嗜硫珠菌屬（英語："Thiomargarita"）是硫發菌科的一個屬，包括液泡硫細菌——納米比亞嗜硫珠菌、Candidatus Thiomargarita nelsonii和Ca. Thiomargarita joergensii。^[4] 2022年，科學家在加勒比海紅樹林發現了該屬的一種極其巨大的細菌，命名為華麗硫珠菌，其細胞肉眼可見，可達2 cm。^[5]

該屬可在富含硫化氫的環境，諸如冷泉、泥火山、鹽水池和富含有機物的沉積物、以及在本格拉洋流和秘魯涼流下發現的沉積物中找到。這些細菌通常歸類為化能營養生物，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。它們利用還原無機硫化物，以此為呼吸作用的電子供體來產生將碳固定成生物質能量，並把富餘的硝酸鹽留存在體內的液泡中。碳固定通過卡爾文循環和可逆克雷布斯循環發生。^[6]當缺乏硝酸鹽時，它們會動用體內的庫存。^[7]
