由真菌绿粘帚霉（Gliocladium virens）产生的抑真菌化合物绿啶（viridin）在液体培养中被发现不可逆地还原为植物毒素绿二醇（viridiol）。转换只发生在存在的viridin生产真菌和viridin生产之后。放射性标记的绿素能迅速被G.菌丝体中的病毒素被还原成放射性标记的病毒二醇，而标记的病毒二醇没有被菌丝体吸收到任何显著的程度。还原为viridiol是独立的培养pH值，碳源，氮源或数量。在泥炭藓中添加葡萄糖和硝酸钙，接种G. viens支持86 μ g viridiol/g泥炭的产量。这种生产系统，当应用于土壤时，可能具有作为除草剂的价值。
The fungistatic compound viridin, produced by the fungus Gliocladium virens, was found to be irreversibly reduced to the phytotoxin viridiol in liquid culture. Conversion occurred only in the presence of viridin-producing fungi and was subsequent to viridin production. Radiolabelled viridin was rapidly taken up by the mycelium of G. virens and reduced to radiolabelled viridiol, while labelled viridiol was not taken up to any significant extent by the mycelium. Reduction of viridin to viridiol was independent of culture pH, carbon source, and nitrogen source or quantity. A simple production system consisting of peat moss amended with dextrose and calcium nitrate and inoculated with G. virens supported propduction of 86 .mu.g viridiol/g peat. This production system, when applied to soil, may have value as a herbicide.
