专性嗜盐菌，盐杆菌，在正常生长条件下保持杆状形态。使用乳过氧化物酶（EC 1.11.1.7；供体：过氧化氢氧化还原酶）催化的碘化和蛋白水解酶处理来证明最近描述的包膜糖蛋白（Mescher, M.F. & Strominger, J.L. (1976) J. Biol. Chem. 251, 2005-2014）是唯一的主要细胞表面该生物体的组成部分。在杆菌肽存在下生长或用蛋白水解酶去除糖蛋白而引起的糖蛋白结构改变所伴随的形态变化强烈表明，它在细胞表面形成刚性基质，并负责维持特征性的杆状形状。
The obligate halophile, Halobacterium salinarium, maintains a rod-shaped morphology under normal growth conditions. Lactoperoxidase(EC 1.11.1.7;donor:hydrogen-peroxide oxidoreductase)-catalyzed iodination and treatment with proteolytic enzymes were used to demonstrate that the recently described envelope glycoprotein (Mescher, M.F. & Strominger, J.L. (1976) J. Biol. Chem. 251, 2005-2014) is the only major cell surface component of this organism. The morphological changes that accompany alteration of the structure of the glycoprotein by growth in the presence of bacitracin or its removal with proteolytic enzymes strongly suggest that it forms a rigid matrix at the cell surface and is responsible for maintenance of the characteristic rod shape.
