Effects of Fermentation Temperature and Aeration on Production of Natural Isoamyl Acetate by Williopsis saturnus var. saturnus

Table 2

Effect of temperature on isoamyl acetate concentration, production rate, specific productivity, and ester/higher alcohol ratio.

Temperature	Isoamyl acetate; (mg L^−1)	Isoamyl acetate production rate^x; (mg L^−1 h^−1)	Isoamyl acetate specific productivity^x; (mg L^−1 cell^−1 h^−1)	Isoamyl acetate/total amyl alcohol ratio^x
15°C	29.43 ± 0.10	0.136 ± 0.0005	0.0235 ± 0.0002	1.75 ± 0.23
25°C	20.72 ± 0.02	0.432 ± 0.0004	0.0436 ± 0.0003	0.69 ± 0.12
Level of significance	**	**	**	**

xIsoamyl acetate production rate, specific productivity, and ester/higher alcohol ratio were calculated at times when isoamyl acetate concentration reach the maximum. **: 𝑃≤0.001.
