FIGURE 2.
C. albicans ada2Δ strains were highly sensitive to challenge with chitosan. (A) The deletion of ADA2 resulted in a mild growth defect in the RPMI and buffer control groups (0.2% acetic acid) and completely abolished growth in 0.2% chitosan. Growth and chitosan resistance were rescued in the revertant strains. (B) Overnight cultures of C. albicans cells were diluted to an OD600 of 0.1 in fresh YPD liquid medium. Growth rates were monitored with a Biowave density meter. The experiments were performed in biological triplicate.
