Abstract
Description
1.微生物の増殖したTSBプレートから単一のコロニーを選択し、TSB培地の入った5mlチューブ内に継代して、微生物を振盪培養器において30℃の条件下で14~24時間培養する。
2.培養液100μlを採取して10倍希釈し、分光計でOD600を検知する(1 OD=1×109 cfu/ml)。
3.水を用いて連続希釈を行い、微生物の濃度を105(8.67×105 cfu/ml)に希釈する。
4.500μlの希釈された微生物(105)を採取し、TSBプレートにおいて培養する。
5.本開示の装置で発生させたプラズマによって、プレート上の微生物を処理する。ノズルの開口部とプレートとの間の距離は、5mmである。
6.微生物を30℃の条件下で1~2日間培養し、増殖阻止域を観察する。
