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（10.8 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24 h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。
Abstract:
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 (10.8cfu/mL) applied,and relative humidity （RH 95%~100%）in preservation period of fruit,the more favorably colonized M.pulcherrima on fresh jujues surface,the colonization ability of it was at 25℃ much more than at 5℃,preinoculation 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 h after inoculation M.pulcherrima on fresh jujube surface.The synergistic factors could improve its colonizing ability,especially calcium propionate(0.2%w/v) could improve its colonizing ability stronger.
