摘要：从麦夸里岛土壤中分离到芽孢杆菌属一新种。这种微生物是嗜冷性的，在0摄氏度及以下的温度下产生孢子。生长的最高温度为25℃。除了与温度的关系外，它与粉状芽孢杆菌最为相似，但不同之处在于，它能够以铵盐为唯一氮源从碳水化合物中产酸，并且不能水解酪蛋白或明胶，不能在大豆琼脂上生长，也不能在5%的氯化钠中生长。建议将其命名为白色芽孢杆菌。营养生物体在生长的所有阶段都呈革兰氏阴性。电子显微镜显示了革兰氏阳性细菌典型的细胞壁结构；另一方面，化学分析表明，在细胞壁制剂中含有广泛的氨基酸和相对较少的氨基糖，这在革兰氏阴性菌中很常见。
Summary: A new species of the genus Bacillus was isolated from Macquarie Island soil. The organism is psychrotrophic, producing spores at temperatures down to and including 0°. The maximum temperature for growth is 25°. Apart from its temperature relations, it most closely resembles B. pulvifaciens, but differs from that organism in its ability to produce acid from carbohydrates with ammonium salts as sole nitrogen source and in its inability to hydrolyse casein or gelatin, to grow on soybean agar or to grow in 5% NaCl. The name Bacillus macquariensis is proposed. Vegetative organisms stained Gram-negative at all stages of growth. Electron micrographs revealed cell-wall structures typical of Gram-positive bacteria; on the other hand, chemical analyses demonstrated in cell-wall preparations a wide range of amino acids and relatively low amounts of amino sugars, as commonly found in Gram-negative species.
