在理想实验条件下，单一生长限制因子的竞争实验结果已被广泛报道，通常为“完全竞争者不能共存”的结论提供了充分的支持。然而，在多种底物限制和营养物质供应不连续或交替的条件下，物种共存是很常见的。由于这种营养供应模式可能在许多自然环境中普遍存在，因此需要了解在这种条件下控制细菌生存和生长的机制。然而，对于在混合培养中生长的个体竞争物种的生理状态，似乎知之甚少。不幸的是，在大多数情况下，缺乏基本信息，如限制营养素的实际浓度。但是，也许最近开发的新的和强大的技术来探索甚至单个细胞的生理特性，将进一步刺激对微生物物种竞争背后机制的研究。
Results of competition experiments with one growth-limiting factor under idealized experimental conditions have been reported extensively, and usually provide ample support for the conclusion that 'complete competitors cannot coexist'. However, under conditions of multiple substrate limitation and discontinuous or alternating supply of nutrients, coexistence of species is quite common. Since such patterns of nutrient supply may be expected to prevail in many natural environments the mechanisms ruling the survival and growth of bacteria under such conditions need to be understood. However, it appears that surprisingly little is known of the physiological state of individual competing species grown in mixed cultures. Unfortunately, basic information such as the actual concentration of limiting nutrients is lacking in most cases. But perhaps the recent development of new and powerful techniques to explore the physiological properties even of individual cells will further stimulate studies into the mechanisms behind the competitiveness of microbial species.
