由四十二種中草藥植物葉收集202株酵母菌，包括白色、紅色與黑色酵母菌。不同植物葉表分佈的酵母菌種類與多樣性不同。將202株菌的培養液以錠片擴散法分別測試對常見的4種革蘭氏陽性細菌與6種革蘭氏陰性細菌的抑制效果，共篩選出23株酵母菌有抑菌能力，鑑定出七屬八種，包括新紀錄種Debaryomyces castellii與Candida edax。

We collected 202 yeast isolates including white, red, and black yeasts from phyllosphere of 42 Chinese medicinal herbs. The yeast flora on different plants were diversitied. A disk diffusion method was used to test the antibacterial ability of 202 yeast isolates against 10 clinical bacteria, including 4 Gram-positive and 6 Gram-negative bacteria. Twenty-three isolates were selected and 11 of them were identified to 7 genera and 8 species, including the new species. Debaryomyces castellii and Candida edax.
