Abstract:	台灣地區夏季炎熱潮濕，為黴菌孳長旺盛的季節。本研究主要的目的為針對夏季時節全麥土司上的黴菌相分佈進行調查，並將黴菌進行分離與鑑定。本研究土司樣本的採集主要從1999年5月至1999年8月，土司樣本包括全麥土司、白土司、以及含添加物的南瓜土司。由實驗結果發現，全麥土司生長的黴菌總菌落數比例為三種土司中最低（佔21.26%）。由全麥土司中所分離鑑定出的黴菌菌屬主要為Wallemia（佔63.67%）、青黴菌（佔32.45%）、麴菌（佔2.64%）、以及不孕性菌落Mycelia sterilia （佔0.73%)。本研究也將5月至8月每月份全麥土司上生長的黴菌菌落數比例進行比較，結果發現不同黴菌在每個月所出現的比例有差異，而造成這些差異的影響因子可能是氣候如溫度、濕度等，或其他因素所造成。 The main purpose of this study was to identify the mycoflora causing mold growth in the packaged wheat toast during summertime. The toast samples were collected three times monthly from May to August, 1999. A comparison of colony numbers from three kinds of toast samples (wheat toast, white toast, and pumpkin toast) shows that the wheat toast has the lowest percentage (21.26%). The major genera of fungi associated with wheat toast were Wallemia(63.67%). Penicillium(32.45%), Aspergillus(2.64%), and sterile colonies of Mycelia sterilia (O.73%). Percentages of total fungal colonies on the wheat toast were also compared month by month in this study. Monthly variations in the frequencies of common genera were observed. It is possible that the distribution of fungal spores was affected by some climatic factors such as temperature, humidity, and others.
