摘  要：
以"圆脆"鲜枣为试材,对拮抗酵母菌(美极梅奇酵母菌)在其表面的定殖情况进行了研究。结果表明:高的接种浓度(108 cfu/mL)、贮藏环境中高的相对湿度(RH 95%~100%)更利于美极梅奇酵母菌在"圆脆"表面的定殖,其在25℃时定殖能力强于在5℃时;接种病原菌对美极梅奇酵母菌定殖能力有一定影响,特别是在接种病菌24h后再接种美极梅奇酵母菌,其定殖能力显著下降;增效因子能提高美极梅奇酵母菌的定殖能力,尤其是0.2%(w/v)的丙酸钙能显著增强美极梅奇酵母菌在"圆脆"表面定殖能力。

摘  要：
Taking ‘Yuancui'jujubes as test material,the colonization ability of antagonistic yeasts(Metschnikowia pulcherrima)on the surface of fresh jujubes was studied.The results showed that higher concentrations of M.pulcherrima(108cfu/mL)applied,and relative humidity(RH 95%~100%)in preservation period of fruit,the more favorably colonized M.pulcherrimaon fresh jujues surface,the colonization ability of it was at 25℃ much more than at5℃,pre-inoculation of pathogen had a negative effect of M.pulcherrima,Especially,the colonization ability of M.pulcherrima was decreased significantly then the inoculation the fungus 24 hafter inoculation M.pulcherrimaon fresh jujube surface.The synergistic factors could improve its colonizing ability,especially calcium propionate(0.2%w/v)could improve its colonizing ability stronger.
