V_(B12)V_(B1)对扁藻繁值和生长的影响实验

An Experiment on Whether V_(B12) and V_(B1) Give Effects to the Growth and Propagation of Platymonas spp.

对比实验表明，V_B_(12)、V_B_1对扁藻的生长无明显影响，不是扁藻生长必需的外源性有机营养。打破了V_B_(12)、V_B_1对单胞藻类生长有明显促进作用的传统结论。

The result of contrasting experiments showed V_B_(12) and V_B_1 did not give obvious effects to the growth and propagation of Platymonas spp. Therefore, a judgement may be formed that V_B_(12) V_B_1 are not the essential external-resource organic nutrition for the growth of Platy-monas spp.
