The ultrastructure of microbial colonies was studied. Inside the colonies three types of intercellular contacts were demonstrated. In the colonies of Gram-negative bacteria, the cells were found to be connected by tight adhesions of outer membranes of the cell walls and membrane bridges. In the colonies of Gram-positive bacteria, the intercellular contacts were formed by fusion of peptidoglucan layers of the cell walls. Bacterial cells were differentiated by the presence of a capsule-like envelope. The obtained data indicate the existence of elements of cellular cooperation and specialization in microbial colonies.
对微生物菌落的超微结构进行了研究。在菌落内部发现了三种类型的细胞间连接。在革兰氏阴性菌的菌落中，细胞通过细胞壁外膜的紧密粘连和膜桥相连。在革兰氏阳性菌的菌落中，细胞间连接是由细胞壁肽聚糖层的融合形成的。细菌细胞因存在类似荚膜的包膜而有所不同。所获得的数据表明微生物菌落中存在细胞合作和专业化的元素。
