When microbial strains compete for the same limiting nutrient in continuous culture, resource-based competition theory predicts that only one strain will survive and all others will die out. The surviving strain expected from theory will be the one with the smallest subsistence or "break-even" concentration of the limiting resource, a concentration defined by the J parameter. This prediction has been confirmed in the case of auxotrophic bacterial strains competing for limiting tryptophan. Because the value of J can be measured on the strains grown alone, the theory can predict the qualitative outcomes of mixed-growth competition in advance of actual competition.
当微生物菌株在连续培养中竞争相同的限制性营养物质时，基于资源的竞争理论预测只有一种菌株能够存活，而其他所有菌株都会灭绝。理论上预期存活的菌株将是对限制性资源维持生存所需或“收支平衡”浓度最小的菌株，该浓度由J参数定义。这一预测在营养缺陷型细菌菌株竞争限制性色氨酸的情况下得到了证实。由于可以在单独培养的菌株上测量J值，该理论可以在实际竞争之前预测混合生长竞争的定性结果。
