Abstract
A moderately halophilic strain of Bacillus, isolated from unrefined solar salt, was capable of growth in the presence of 4 M NaCl. Maximal growth was obtained in a medium containing 1 to 2 M NaCl. The organism produced protease when cultivated aerobically in media containing 0 to 3 M NaCl or 0 to 2 M KCl. The protease activity was optimal at 0.5 M NaCl and 0.75 M KCl.
摘要
从粗制日晒盐中分离出的一株中度嗜盐芽孢杆菌能够在4M氯化钠存在的情况下生长。在含有1至2M氯化钠的培养基中可实现最大生长。该微生物在含有0至3M氯化钠或0至2M氯化钾的培养基中需氧培养时会产生蛋白酶。蛋白酶活性在0.5M氯化钠和0.75M氯化钾条件下最佳。
