Abstract
|
|
|
|
Persimmons are cultivated mostly in Asian countries especially in Korea, Japan, and China. One of the most common types of persimmons in Asia is astringent persimmon; a wild species with a characteristic astringent taste until it ripens. Persimmon Calyx is the most common domesticated persimmon species and highly commercialized currently. Persimmon calyx species is briskly used in treating a number of disease conditions including but not limited to cough and bronchial troubles. This study was therefore conducted to investigate the mechanism of interaction between stalk of persimmon and a given yeast strain. The yeast stain separated from the stalk of persimmon was inoculated into four different types of samples; Persimmon, leaves of persimmon tree with leaf blight, naturally dried stalk, and artificially dried stalk. The antimicrobial activity of the yeast strain was also tested on Coprinekkus radians, Fusarium oxysporum, and Rhizopus oryzae microorganisms. The study found that the new yeast strain inhibited the growth of C. radians, F. oxysporum, and R. oryzae which are known to be disease causing organisms to persimmon tree species. This study therefore provides vital knowledge for the effective cultivation of disease free persimmons and animatedly in preventing anthracnose or leaf blight. Our future study will aim at the taxonomic identification of the yeast strain and analysis of its secretion compounds on the culture medium. Further investigations will also explore the antimicrobial potential of the yeast strain and examine its applicability as an insecticides or fungicides in the future.
