总结：解淀粉芽孢杆菌在生长过程中从培养基中吸收无机离子。它们在细胞质组分和被膜之间的分布从几乎完全细胞质到完全细胞膜结合，顺序为：K+，4.7%; Mg 2+，32.0%;磷酸盐，60.2%; Na+，80.4%; Ca 2+，96.1%; Cl−，100%细胞膜结合。在胞外酶分泌速率从最小值到最大值的过渡期间，以下离子的细胞内水平保持不变：K+，583±54 mm;磷酸盐，459±40 mm; Mg 2+，56±6 mm; Na+，22±4 mm。
Summary: Bacillus amyloliquefaciens took up inorganic ions from the medium during growth. Their distribution between the cytoplasmic fraction and the envelope varied from almost exclusively cytoplasmic to completely envelope-bound in the order: K+, 4·7%; Mg2+, 32·0%; phosphate, 60·2%; Na+, 80.4%; Ca2+, 96·1%; and Cl−, 100% envelope-bound. During the transition from minimum to maximum rate of extracellular enzyme secretion the intracellular levels of the following ions were unchanged at K+, 583±54 mm; phosphate, 459±40 mm; Mg2+, 56±6 mm; and Na+ 22±4 mm.
