マラカイトグリーンに代わるミズカビ病防除剤としての次亜塩素酸ナトリウム(NaOCl)の有効性を明らかにするために,タイにおいてコイ卵から分離したミズカビSaprolegnia diclina (THMK0306)に対するNaOClの菌糸発育阻止効果と遊走子発芽阻止効果を検討した。その結果, NaOClの菌糸最小発育阻止塩素濃度は20mg/L(60分間暴露),遊走子最小発芽阻止塩素濃度は2.5mg/L(5分間暴露)であった。
We examined the fungicidal efficacy of sodium hypochlorite (NaOCl), a food additive, on a pure strain THMK0306 of Saprolegnia diclina Humphrey isolated from the eggs of carp Cyprinus carpio in Thailand. The efficacy was evaluated by inhibitive activities on mycelial growth and zoospore germination of the fungus after NaOCl treatments at various combinations of residual chlorine concentration and exposure time. The minimum inhibitive concentration (MIC) for the mycelial growth was 20mg/L (60 min exposure), and the MIC for the zoospore germination was 2.5mg/L (5 min exposure). These results indicate that NaOCl has strong fungicidal activities against the fungus from the tropical country.
