Claims (1)

토양을 채취하여 nutrient agar배지에 희석평판법으로 30℃에서 3일간 배양하여 얻어진 세균군 중 형광색소 및 점성물질을 생산하는 균주만을 분리하여 정제코져 하는 점토와 혼합배양에 의해 점토내의 철분 함량이 가장 많이 줄어드는 세균주를 선별하여 4℃에 보관하여 세균주로 하며, 보통 실험에 있는 곰팡이 균주(약 50여종)와 토양으로부터 Czapek배지를 사용하여 28℃, 5일간 배양하여 분리 얻어진 30여 종의 균주를 정제코져 하는 점토와 혼합배양을 통해서 철분함량이 가장 많이 줄어든 곰팡이균주를 선별하여 4℃에 보관하여 곰팡이 균조하여 점토와 세균주와 곰팡이균주를 혼합 미생물을 배양하므로서 점포에 함유된 철분을 융출 분리하며 미생물 분비의 점액성 물질에 의해 점토의 가소성을 증진시키는 Bacteria leaching법에 의한 점토의 철분제거 및 정제방법.The iron content in the clay is the highest by the clay and mixed culture that separates only the strains that produce fluorescent pigments and viscous substances from the bacterial group obtained by diluting the soil and cultivating them at 30 ℃ for 3 days in a nutrient agar medium. Reduced bacterial strains are selected and stored at 4 ℃ to be bacterial strains. Purification of 30 strains isolated from fungi strains (about 50 species) and soil obtained by culturing at 28 ℃ for 5 days using Czapek medium Fungus strains with the most reduced iron content are selected and stored at 4 ° C through cultivating clay and mixed culture to mold fungi and cultivate mixed microorganisms of clay, bacterial and fungal strains to melt and separate the iron contained in the store. Iron removal and purification of clay by Bacteria leaching method that enhances plasticity of clay by secretion mucus Way. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
