*
Each value is mean±SD of triplicate experiments (n=50).
Different small letters indicate significant differences for the different clove oil dose at the same salinity degree (p<0.05).
Different capital letters indicate significant differences for the different salinity degree at the same clove oil dose (p<0.05).
