Abstract
Within the limits of this study, it was found that 5 ppm of cobalt was adequate to give good levels of vitamin B(12). The vitamin B(12) precursor 5,6-dimethylbenzimidazole was found to be adequate at 10 ppm in the absence of aeration. In the presence of aeration, a zero level of precursor was found to be most desirable. The analysis of variance showed aeration to be highly significant, and the aeration and precursor interaction to be significant. No other significant effects were observed.
摘要
在本研究范围内，发现5 ppm的钴足以使维生素B12达到良好水平。发现在不曝气的情况下，10 ppm的维生素B12前体5,6-二甲基苯并咪唑就足够了。在曝气的情况下，发现前体水平为零是最理想的。方差分析表明曝气具有高度显著性，曝气与前体的相互作用具有显著性。未观察到其他显著影响。
