  2. The data are means of three biological replicates and are mole % of total fatty acids contents; values after (±) are standard deviations
  3. In most of the cases, values of standard errors are almost half the values of standard deviations (data not shown)
  4. Values in bold represent quantitatively dominant fatty acids
  5. nd not detected, PV p value of ANOVA
  6. 0.5 % salt was treated as a control for the comparison of increasing effects of salinity
