摘  要：
对简易气调(MA)贮藏过程中不同部位绿芦笋表面菌落总数随贮藏时间的变化规律进行研究,并对从绿芦笋表面分离到的菌株进行初步鉴定。结果表明:经简易气调贮藏的绿芦笋前10d表面微生物数量增长较缓慢,之后其数量骤然增加,贮藏到第14天时达到7.40×107CFU/g,其后随着贮藏时间延长微生物数量略有减少。在绿芦笋贮藏后期,从其表面共分离到细菌24株,分属于埃希氏菌属、假单胞菌属、欧文氏菌属和微球菌属等10个属;真菌8株分属于青霉属、交链孢霉属、腐霉属、酵母属。

摘  要：
This paper reports the observation of changes in total count of bacteria colonies on the surface of scale leaves and on the root cross-section of green asparagus during modified atmosphere(MA) storage and the preliminary isolation and identification of isolated microorganisms.There was a very slow increase in microbial population during the first 10 days of MA storage,followed by a sudden increase,reaching up to 7.40 × 107CFU/g on the 14th day.Subsequently,microbial population decreased slightly with prolonged length of storage time.A total of 24 bacterial strains 8 fungal strains were isolated from the surface of green asparagus that began to decay,which were identified to belong to Pediococcus,Escherichia,Pseudomonas,Erwinia,Micrococcus,Leuconostoc,Staphylococcus,Sporosarcina,Alcaligenes or Acetobacter and to belong to Penicillium,Alternaria,Pythium or Saccharomyces.
