The fungal strain Colletotrichum salsolae SCSIO 41021 (Glomerellaceae) was obtained from the inside of the stem of the mangrove plant Kandelia candel (L.) Druce (Rhizophoraceae) collected in Daya Bay, China (N22° 44′ 19.82″, E114° 31′ 58.18″) in March 2012. Strain stored on PDA slants at 4 ℃ was cultured on PDA agar plates and incubated for 7 days. Seed medium (potato 200 g, dextrose 20 g, NaCl 2.5 g, distilled water 1000 mL) in 50-mL Erlenmeyer flasks was inoculated with strain and incubated at 25 ℃ for 48 h on a rotating shaker (180 rpm). Production medium of 200-mL PDB in 1000 mL flasks was inoculated with 10 mL seed solution. Flasks were incubated at 25 ℃ under static stations and daylight.
