Chosen 4 species of genus Rhodotorula were isolated from leaves,flowers and soils in South Viet Nam were grown in broken grain of ordinary rice (size 1-2 mm) which were starched by solid-state method for receiving red yeast biomass.The medium component and culture condition medium of solid -state culture method were determined.Red yeast biomass were coloured from orange to red.Nutrition rate of enriched broken grain of ordinary rice product is higher than other researches.The result can be applied for Microbial Production of Food grade pigments as well as supplement production for animal feed technology.
