Fig. 9. Fourier transform infrared (FTIR) spectroscopy analysis of worms treated with EISO, α- and β-santalol. Untreated and treated worms of NL5901 strain (n = 80–100 worms per treatment) were ground with 100 mg of potassium bromide pellets and dried under vacuum evaporator for 48 h. The infrared spectra were scanned from 400 to 4000 cm−1 using Bruker Tensor 27 series spectrophotometer.
