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
