The authors verified that axenic culture of Bacillariophyceae and Dinophyceae was more difficult to obtain than those of Chlorophyceae and Haptophyceae because of them intricated external morphology.
This step was repeated several times to obtain an axenic culture. The axenic condition of the cultures was tested by transferring pieces of agar block with the cyanobacterial cultures to LB agar medium plates.
Like amino acids, dipeptides (two amino acids joined by a peptide bond) are transported into roots (Komarova et al 2008), as demonstrated by the presence of intact dipeptide molecules in plants grown in axenic culture (Paungfoo-Lonhienne et al.

After treatment of axenic culture of Giardia with different concentrations of kramecyne, trypan blue staining allowed counting cells and also determining the proportion of viable and nonviable cells; Figure 2 shows blue-stained cells, indicating that the membrane of a nonviable cell has been permeated and allowed to enter the dye; in addition the staining allows observing that trophozoites did not appear to undergo structural modification by action of kramecyne; trophozoites did not lose their size and shape and did not show damage in nucleus structure, although ultrastructural studies are necessary to determine damage in a more specific way.
