Abstract
Bacillus megaterium spores have a characteristic polar knob and equatorial ridge, or groove. During germination, the spore case appears to split along this ridge, and thus allows the new cell to emerge. Mechanically ground spores also split along this ridge, one part of the spore case being hinged to the other, the ridge being evident along a free edge. The equatorial ridge appears to be an area of suspectibility to mechanical pressures and, perhaps, in normal germination, to enzymic action as well.
摘要
巨大芽胞杆菌的芽孢具有特征性的极生 knob 和赤道脊，或槽。在萌发过程中，芽孢壳似乎沿着这条脊分裂，从而允许新细胞出现。机械研磨的芽孢也沿着这条脊分裂，芽孢壳的一部分以铰链连接到另一部分，脊在自由边缘处明显可见。赤道脊似乎是对机械压力敏感的区域，也许在正常萌发过程中，也是对酶作用敏感的区域。
