Adhesion to glass of actively growing cells of the thermophilic Bacillus licheniformis, isolated from the Medyaginskaya test borehole (Yaroslavl' oblast), was studied. The reversible adhesion (RA) manifests itself in a decline of cell density (short of cell lysis) in the liquid culture over the first 20-40 min of growth followed by normal exponential growth. The RA is minimal under favorable growth conditions but increases when cells are transferred to a new medium, especially one with a pH, temperature, salinity, or concentration of Ca2+ ions nonoptimal for the given species. Under unfavorable growth conditions, the adhesion becomes irreversible. The obtained data suggest that RA represents an adaptation mechanism important for population survival.
对从梅德亚金斯卡娅试验钻孔（雅罗斯拉夫尔州）分离出的嗜热地衣芽孢杆菌活跃生长细胞与玻璃的粘附情况进行了研究。可逆粘附（RA）表现为在生长的最初20 - 40分钟内液体培养物中细胞密度下降（未发生细胞裂解），随后呈正常指数生长。在有利的生长条件下RA最小，但当细胞转移到新培养基中时会增加，尤其是转移到pH、温度、盐度或Ca2 +离子浓度对该特定物种并非最优的培养基中时。在不利的生长条件下，粘附会变为不可逆。所获得的数据表明，RA是一种对种群生存很重要的适应机制。
