The aim of this work was the estimation of microbial contamination of the air in "small gastronomy point". The study included three places, which have been separated on the ground of their function: 1. area of subsidiaries, 2. area of distribution (sale and serving meal), 3. area of consumption. The total numbers of aerobic mesophilic bacteria, yeasts and moulds were determined by sedimentation method. Taxonomy units of fungal aerosol were also estimated. The samples of air were collected in 16 investigation points in the morning (8-8.30) and in the afternoon (14-14.30). Four series of measurements were carried out and in general 128 of air samples were tested. The results showed that numbers of bacteria, yeasts and moulds were variable and received respectively 30-3397, 0-254 and 0-138 cfu x m(-3). Microbial contamination of air changed depending on area character (the highest average count of bacteria occurred in the air of consumption area and fungi in subsidiaries area), time of a day (contamination of the air increased in the afternoon) and determination date. Only in single samples the numbers of bacteria and fungi were higher than recommended level. Pigmentary bacteria had high participation in total count of bacteria and filamentous fungi were represented mostly by Penicillium sp. and Cladosporium sp.
这项工作的目的是评估“小型美食店”空气中的微生物污染情况。该研究涵盖了三个根据功能划分的场所:1. 附属区域;2. 配送区域(销售和供餐);3. 消费区域。通过沉降法测定需氧嗜温菌、酵母和霉菌的总数。还对真菌气溶胶的分类单位进行了评估。空气样本于上午(8 - 8:30)和下午(14 - 14:30)在16个调查点采集。进行了四轮测量,共测试了128个空气样本。结果表明,细菌、酵母和霉菌的数量各不相同,分别为30 - 3397、0 - 254和0 - 138 cfu×m⁻³。空气中的微生物污染因区域特征(消费区域空气中细菌平均计数最高,附属区域真菌最多)、一天中的时间(下午空气污染增加)和测定日期而有所变化。仅在单个样本中,细菌和真菌的数量高于推荐水平。色素细菌在细菌总数中占比很高,丝状真菌主要为青霉属和枝孢属。
