采用滤纸片扩散法测定不同浓度的一道茶、二道茶在浸泡12 h后对大肠杆菌、枯草芽孢杆菌、黑曲霉、青霉四种微生物的抑制作用。一道茶、二道茶对大肠杆菌、枯草芽孢杆菌有较明显的抑制作用,一道茶的抑制作用大于二道茶,对黑曲霉、青霉没有抑制作用。一道隔夜茶水对大肠杆菌、枯草芽孢杆菌的最小抑菌浓度分别为0.063 g/mL、0.077 g/mL。本实验证实了隔夜茶水的抑菌作用,为其变废为宝提供理论依据。
採用濾紙片擴散法測定不同濃度的一道茶、二道茶在浸泡12 h後對大腸桿菌、枯草芽孢桿菌、黑麯黴、青黴四種微生物的抑製作用。一道茶、二道茶對大腸桿菌、枯草芽孢桿菌有較明顯的抑製作用,一道茶的抑製作用大于二道茶,對黑麯黴、青黴沒有抑製作用。一道隔夜茶水對大腸桿菌、枯草芽孢桿菌的最小抑菌濃度分彆為0.063 g/mL、0.077 g/mL。本實驗證實瞭隔夜茶水的抑菌作用,為其變廢為寶提供理論依據。
채용려지편확산법측정불동농도적일도다、이도다재침포12 h후대대장간균、고초아포간균、흑곡매、청매사충미생물적억제작용。일도다、이도다대대장간균、고초아포간균유교명현적억제작용,일도다적억제작용대우이도다,대흑곡매、청매몰유억제작용。일도격야다수대대장간균、고초아포간균적최소억균농도분별위0.063 g/mL、0.077 g/mL。본실험증실료격야다수적억균작용,위기변폐위보제공이론의거。
This experiment used filter paper method to determine each kind of density of the tea standed for night＇t inhibitory action with E.coli,Bacillus subtilis.Aspergillus and Penicillium.The tea was the first and the second operation water immersed for 12 h,which had bacteriostat circle diameter and the bacteriostat effect was very obvious,the first operation water had the strongest inhibitroy effect,but it was not effective to Aspergillus and Penicillium.The minimum inhibit concentration（MIC） of the first operation water for E.coli,Bacillus subtilis were determined as 0.063 g/mL,and 0.077 g/mL.It was confirmed the tea standed for night had inhibitory action effect on bacteria,and provided the theoretical basis for making waste profitable.
