Simultaneous limitation of microbial growth by two or more nutrients is discussed for dual carbon/nitrogen-limited growth in continuous culture. The boundaries of the zone where double-limited growth occurs can be clearly defined from both cultivation data and cellular composition and they can be also predicted from growth yield data measured under single-substrate-limited conditions. It is demonstrated that for the two nutrients carbon and nitrogen the zone of double nutrient limitation is dependent on both the C:N ratio of the growth medium and the growth (dilution) rate. The concept on double-(carbon/nitrogen)-limited growth presented here can be extended to other binary and multiple combinations of nutrients.
本文讨论了在连续培养中，两种或更多种营养物质同时限制微生物生长的情况，即双碳/氮限制生长。可以从培养数据和细胞组成清晰地界定双限制生长发生区域的边界，并且也可以根据在单底物限制条件下测得的生长产率数据进行预测。结果表明，对于碳和氮这两种营养物质，双营养限制区域取决于生长培养基的碳氮比和生长（稀释）速率。这里提出的双（碳/氮）限制生长概念可扩展到其他二元和多元营养物质组合。
