| 摘 要： | 将青霉PT95菌株发育成熟的菌核在不同环境条件下保存,结果发现:黑暗、低温、氮气、pH 6~8条件下有利于菌核内类胡萝卜素保持稳定。6种金属离子中,Fe3+、Fe2+、Al3+对类胡萝卜素稳定性影响最大,Mn2+的影响最小。氧化剂H2O2对PT95菌核中类胡萝卜素稳定性的影响不大,而还原剂Na2SO3的影响较大。

| Abstract: | This study examined the influence of light,temperature,gas,pH,metallic ions,oxidizing and reducing medium on the stability of carotenoid in sclerotia of Penicillium sp.PT95.The results showed that dark,lower temperature,nitrogen and pH values of 6~8 favored the stability of carotenoid.Among six metallic ions tested,Fe3+,Fe2+ and Al3+ had the heavy negative effect on the stability of pigment,whereas Mn2+ had the smaller effect.The results also showed that the reducing medium Na2SO3 had the more strong negative effect on the stability of carotenoid than that of oxidizing medium H2O2. |
