The effect of manure concentration on the growth of the heterogeneous microbial population under batch condition was studied. Four manure concentrations were used in the study. The dehydrogenase activity was used as a measure of the active biomass in the manure. The chemical oxygen demand test was used to measure the change in organic material caused by biological activities. The growth curve of the heterogeneous microbial population in swine manure was essentially similar to that of a pure culture grown batchwise in that it had the four principle phases: lag, exponential growth, stationary, and death. The exponential growth phase followed a diauxic growth pattern. High concentration of manure had an inhibitory effect on the microbial growth. Manure diluted less than 1:3 (manure:water) depressed the specific growth rate of the microbial population.
研究了分批条件下粪便浓度对异质微生物群体生长的影响。该研究使用了四种粪便浓度。脱氢酶活性被用作衡量粪便中活性生物量的指标。化学需氧量测试用于测量生物活动引起的有机物质变化。猪粪中异质微生物群体的生长曲线与分批培养的纯培养物基本相似，即具有四个主要阶段：延迟期、指数生长期、稳定期和死亡期。指数生长期遵循双相生长模式。高浓度粪便对微生物生长有抑制作用。稀释倍数小于1:3（粪便:水）的粪便会降低微生物群体的比生长速率。
