Study Of Biosynthesis Silica Nanop Articles From Rice Husk Use Fusarium Oxysporum

Abstract

Silica nanoparticles biosynthesis utilizing rice husk as a source of silica as well as a substrate for the growth Fusarium oxysporum. Fusarium oxysporum was grown in media pH 4-6, Incubation temperature 27 ° C, 4 I 5 empty space and aeration system with an orbital shaker 200 rpm. Harvesting biomass F.oxysporum done at n hour, ie when the cells entered the stationary phase based on the growth curve. SEM analysis results seen loamy to each other and have a particles size with variations in size between 200-lOOQ nm. Three peak which has the highest peak of the 12 peak is found in the FTIR absorption spectrum, which is located at 34U8J8 cm·1 for H20 clusters, 1639.04 cm·1 to cluster C03 2 ', and 1078.71 cm·1 for the_ group Si-0-Si this shows the husk of with F.oxysporum treatment has changed the structure of basic forms (amorphous) - ·
