摘要:

本实验研究了抗坏血酸(VC)、还原性谷胱甘肽(reduced glutathione,GSH)和半胱氨酸(cysteine,Cys)3 种抗氧化剂分别作为预防剂和治疗剂对硅酸钠和对应pH值溶液胁迫下粉红单端孢(Trichothecium roseum)孢子存活力的保护作用。结果表明,3 种抗氧化剂均能使硅酸钠胁迫下孢子的生存能力部分恢复,而使对应pH值胁迫下孢子的生存能力80%恢复;3 种抗氧化剂中VC的保护效果要优于GSH和Cys;3 种抗氧化剂作为预防剂的效果要优于其治疗效果。

Abstract:

The protective effects of three antioxidants on spores of Trichothecium roseum under sodium silicate and
corresponding pH stress were studied by comparing the spore viability. The results showed that all the investigated
antioxidants enabled the sodium silicate-stressed spores to restore partially their viability. Moreover, the viability of 80%
spores under corresponding pH stress was restored. VC had better protective effect on Trichothecium roseum spores than
GSH and Cys. The preventive effect of the three antioxidants was better than their therapeutic effect.

Key words: antioxidants, sodium silicate, spore viability
