Effect of nitrogen source on aroma production by Trichoderma viride

Abstract

The effect of nitrogen source on the aroma production of a strain of Trichoderma viride was investigated. The compound giving the culture its characteristic coconut-like aroma was identified as 6-pentyl-α-pyrone. Variation of the nitrogen source affected the quantity of the lactone produced but did not cause a significant difference in the aroma of the culture. The lactone formation was also affected by the method of cultivation, and sporulation was not essential for its formation. © 1985 Springer-Verlag.
