Preliminary Study on Antiviral Substances Produced by Bacteria Strain CZ and its Optimal Fermentative Conditions

The authors studied the fermentation conditions of a kind of antiviral bacteria which was filtrated from the seeds of the tobacco. The results indicated that the most appropriate fermentation medium was NB medium and the optimal fermentation parameters were pH 8.0, 25℃, 60 hours. Its anti-material could be protein.
