TABLE 4.

Spearman’s correlation coefficient analysis between germination ratio (%)/mycelium growth rate (μ/h) and the VOCs detected in the cell-free supernatants of D. hansenii strains.

Mold growth	Mold species	Volatile compounds	R-value (spearman)ab	Strength of association
Germination ratio	C. inversicolor	Acetic acid	−0.795	Strong
	C. inversicolor	3-methylbutanoic acid	−0.851	Strong
	C. inversicolor	2-pentanone	−0.731	Strong
	P. roqueforti	Acetone	−0.860	Strong
	P. roqueforti	2-phenylethanol	−0.753	Strong
Mycelium growth rate	P. roqueforti	2-phenylethanol	−0.881	Strong

^aR = 0 none; −0.3 ≤ R ≤ −0.1 week; −0.6 ≤ R ≤ −0.4 moderate; −0.9 ≤ R ≤ −0.7 strong; −1 perfect. ^bThe association was considered significant (P < 0.05), P-values of all compounds mentioned above were below 0.05.
