The sensitivity of the dissociative variants "R", "RS" and "S" of the spore-forming bacilli to some lytic agents (lysozyme, sodium lauryl sulphate, lipase, trypsin and some of their associations) has been studied. The research has been carried out on 32 strains: 14 "R", 14 "RS" and 4 "S" of different species of the genus Bacillus. The results have shown that the sensitivity to the studied lytic agents is strictly correlated, not to the species, but to the dissociative phases: these results are in accordance with those obtained in previous researches, carried out by the same Authors, on other characters, both morphological and biological, of the same variants. Thus, also through this way, it is possible to reach the conclusion that within this genus, there is more similarity among the different species of the same dissociative phase than among different dissociative variants of the same species. The results obtained in the present study allow to advance hypothesis, based also on the data of the literature, about the composition of the cell walls of the three above mentioned dissociative variants of the strains belonging to the genus Bacillus.
已对芽孢杆菌的解离变体“R”、“RS”和“S”对某些溶菌剂（溶菌酶、十二烷基硫酸钠、脂肪酶、胰蛋白酶及其一些组合）的敏感性进行了研究。研究针对32株菌株开展：芽孢杆菌属不同种的14株“R”、14株“RS”和4株“S”。结果表明，对所研究溶菌剂的敏感性并非与菌种严格相关，而是与解离阶段严格相关：这些结果与同一作者之前对相同变体的其他形态学和生物学特征所开展研究的结果一致。因此，通过这种方式也有可能得出结论，在该属内，同一解离阶段的不同种之间的相似性高于同一种的不同解离变体之间的相似性。本研究获得的结果有助于基于文献数据对芽孢杆菌属菌株上述三种解离变体的细胞壁组成提出假设。
