Preliminary study on the induction of zinc to playmomas subcordiformis metallothionein-like / 中国海洋药物

ABSTRACT

When Playmonas cardiformis is exposed to different ZnSO4 concentration, its growth rate decreases gradually with the increase of ZnSO4 concentration which is more than 1 mmol?L~-1. More than 8 mmol?L~-1 ZnSO4 can lead to the death of playmonas subcordi- formis. But the production of MT-like increases with the increase of ZnSO4 concentration by AAS determination. The effect of indution is remarkable. The production of MT-like reaches 2. 1ing per gram wet weight when the concentration of ZnSO4 is 1 mmol?L~-1.
