Isolation, Identification and Inhibition of Microorganisms Causing Mildew and Rot of Zizyphus mauritiana Lam.
The microorganisms causing rot of Zizyphus mauritiana Lam.were isolated and identified,and the microbial species and the methods of inhibition were researched.6 bacteria and 24 moulds were isolated by morphological and molecular methods.The results showed that bacteria belonged to Pantoea agglomerans(Enterobacteriaceae),and moulds belonged to Alternaria alternate,Alternaria alternate,Epicoccum nigrum,Fusarium equiseti,Phoma herbarum,Exserohilum rostratum,respectively,among which Alternaria was the dominant fungi.And the inhibition test of microorganisms was carried out by ultraviolet light irradiation,soaking with the mixed solution of potassium sorbate and phytic acid,soaking in hot-water (55 ℃) for 10 mins,storing at low temperature (4 ℃),and storing room temperature.The effect of ultraviolet irradiation on green jujube storage was not obvious,soaking with the mixed solution of potassium sorbate and phytic acid did harm to sensory properties of green jujube,soaking in 55 ℃ hot-water could prolong storage time,but cause some wilting.Low temperature (4℃) storage achieved better results,and had not significant impact on sensory properties of green jujube.
