一个多世纪以来，微生物学家一直在努力研究无菌或“纯”培养物。在医学和工业微生物学、微生物遗传学和生理学方面取得的结果使这一努力是值得的。在所有这些类型的研究中，需要无菌技术来获得关于因果关系的明确结论。然而，无菌培养技术隐藏了自然界中常见的微生物之间的关系，例如本文所描述的微生物。细菌之间的生态关系偶尔会被报道，但人们并没有意识到它们的意义。1924年，巴文达姆描述了几个细小的、细长的身体，附着在紫色硫磺细菌Chromatum warmingii的较大细胞上，他认为这些身体是细胞之间的芽或桥梁。用他自己的话说：“在1922年6月一个非常炎热的日子……就在一场雷雨前不久……我看到了令人惊讶的如此丰富的芽和桥……这一现象可能会持续几天。在那之后，大多数色马提亚都定居在培养器皿的玻璃墙上。
For more than a century, microbiologists have tried to work with axenic, or “pure”, cultures. The results obtained for medical and industrial microbiology, microbial genetics, and physiology have made the effort worthwhile. Axenic technology is required to obtain clear-cut conclusions about cause-effect relationships in all these kinds of studies. Nevertheless, the axenic culture technique hides relationships among microorganisms, such as the ones described in this article, that are common in nature. Ecological relationships among bacteria occasionally have been reported without the recognition of their meaning. In 1924, Bavendamm described several small, elongated bodies attached to the larger cells of the purple sulfur bacterium Chromatium warmingii which he thought were buds or bridges between cells. In his own words:“On a very hot day in June 1922..., shortly before a thunderstorm... I saw an extraordinary surprising wealth of such buds and bridges.... The phenomenon could be seen for several days. After that most Chromatia had settled to the glass walls of the culture vessel.”
