A major goal of microbial ecology is the identification and characterization of those microorganisms which govern transformations in natural ecosystems. This review summarizes our present knowledge of microbial interactions in the natural sulfur cycle. Central to the discussion is the recent progress made in understanding the co-occurrence in natural ecosystems of sulfur bacteria with contrasting nutritional requirements and of the spatially very close associations of bacteria, the so-called phototrophic consortia (e.g. 'Chlorochromatium aggregatum' or 'Pelochromatium roseum'). In a similar way, microbial interactions may also be significant during microbial transformations other than the sulfur cycle in natural ecosystems, and could also explain the low culturability of bacteria from natural samples.
微生物生态学的一个主要目标是识别和表征那些在自然生态系统中主导转化过程的微生物。本综述总结了我们目前对自然硫循环中微生物相互作用的认识。讨论的核心是在理解营养需求不同的硫细菌在自然生态系统中的共生现象以及细菌在空间上非常紧密的关联（即所谓的光合共生体，如“聚集绿菌属”或“玫瑰色佩洛绿菌属”）方面所取得的最新进展。同样，在自然生态系统中除硫循环之外的微生物转化过程中，微生物相互作用可能也很重要，并且这也可以解释从自然样本中分离细菌时可培养性较低的原因。
