Alpha amylase (α-amylase) enzyme is used as a thinning agent in the starch hydrolysis and it is widely used in the food processing, paper and textile industries. The intention of the present study was to analyse the α-amylase activity in solid state fermentation and submerged fermentation using immobilized cells of Aspergillus oryzae (A. oryzae) and Bacillus cereus (B. cereus), respectively. Th...

Abstract Concrete with high ductility, workable, strength, easy to flow without compaction, and durable is a concrete need in the future. this quality, one of which make self-compacting (SCC). This paper reports performance self compacting (SCC) containing rice hush ash. Rice husk ash waste from burning husks. The purpose study was determine SCC addition specimens were made using (RHA) (NRHA). ...

Rice is the second most extensively consumed food ingredient, and its by-products in paddy field include rice husk straw. ash, resulting from burning, considered an environment menace, inducing negative effects on area which it disposed of. In this study, was applied as a silicate source to obtain mesoporous silica material. Characterization techniques confirmed well-ordered mesophase resemblan...

Abstract Application of different forms silicon sources may influence rice production and quality. It is believed that properties nanosized particles differ significantly from those the original bulk material. This study aimed to investigate effects application silica nanoparticles extracted husk ash, called nanobiosilica (NBS), on growth, productivity, milling quality as compared ash (RHA), so...
