A total of 23 endophytic fungal isolates were isolated from C. mollissimum; 18 isolates were recovered from the leaves and 5 isolates from the plant stem. All fungal isolates were screened for antimicrobial activity. Four of the endophytic fungal isolates inhibited growth of bacteria and/or fungi (Table 1). Of these, only one isolate, CB 007 (WA), inhibited the growth of both bacteria (B. subtilis) and fungi (A. niger and A. fumigatus); therefore, this isolate was selected for further experimentation.
