Comparison of pure DNA yield and purity, obtained from four strains of E. siliculosus by two different methods: the new and old [47].

Total amounts of nucleic acids were calculated in a final volume of 40 µL.(a)Data are reported as means ± SE from five independent nucleic acid extractions, for both methods. ‘New’ refers to the method developed in this study; ‘Old’ refers to a previously published protocol based on CTAB extraction buffer. According to one-way ANOVA and post-hoc Tukey Test at 95% confidence interval, an asterisk (*) indicates the significantly differences between the yields of the two methods.
