Endophytic fungi from Musa acuminata leaves and roots in South China

Abstract

One hundred and sixty-three endophytic fungal cultures were isolated from 200 leaf samples of Musa acuminata trees, which were soaked in 36% formaldehyde solution for surface sterilization. They belonged to the genera of Gloeosporium musae (45%), Myxosporium spp. (11%), Deightoniella torulosa (8.5%), Alternaria tenuis (7.9%), Sphaceloma spp. (7.4%), Aureobasidium spp. (4.3%), Melida spp. (1.8%), Uncinula spp. (1.8%), Penicillium spp. (1.8%), Aspergillus spp. (1.2%), Sarcinella spp. (1.2%), Cladosporium sp. (0.6%), Cephalosporium sp. (0.6%) and sterile mycelium (6.7%). Sixty-eight endophytic fungal cultures were isolated from 100 root samples. They respectively belonged to the genera of Aspergillus spp. (31%), Paecilomyces spp. (16%), Penicillium spp. (15%), Fusarium spp. (10%), Gloeosporium musae (6%), yeast (3%), Deightoniella torulosa (3%), Spicaria sp. (1.4%), Cephalosporrium sp. (1.4%), Meliola sp. (1.4%) and sterile mycelium (10%). Water agar (containing 50 μg chloramphenicol ml−1 and 50 μg streptomycin ml−1) seemed to be a better medium for isolation of endophytic fungi than potato-dextrose agar (PDA, containing 50 μg chloramphenicol ml−1 and 50 μg streptomycin ml−1).
