| Method |
"The washed chloroform extract was evaporated to near dryness under dry N2
and transesterified using 2% H2SO4 in methanol, as described by Silbert et al. (25). The methyl esters were extracted into pentane and concentrated under N2 prior to analysis." |
| Comments |
"The presence of alcohols in rich growth media results in a considerable change in fatty acid composition (Table 1). The degree of this variation in fatty acid composition is
strongly dependent upon alcohol concentration. For ethanol, this relationship is shown from 1 to
4%. The alcohol concentration required to cause a given change in fatty acid composition is inversely related to chain length, as is toxicity.
The molar effectiveness of alcohols in eliciting an adaptive change in fatty acids is directly related to their lipid solubility, indicative of a
direct membrane interaction (Fig. 1). The highest concentrations of alcohols reported in Table 1 represent concentrations of alcohols causing
30 to 50% growth inhibition after 3 h under the described conditions of incubation." |
