Optimal Condition for Carotenoid Production by Rhodotorula rubra in Conjunction with Probiotic from Lactobacillus acidophilus by Using Corn Dust as Substrates

Abstract

Current with the cultivation of maize increasing every other year. Each year, the waste from harvesting the bark, straw, stalks and seeds decisive and dust. Farmers burn a significant impact on the environment. Industrial animal farming, agricultural waste materials can be utilized in the production of animal feed but dust corn used to make animal feed, which must be disinfected with frustration. And may be costly and can be used as raw material in the production of animal feed to produce pigment carotenoids from yeast Rhodotorula rubra from corn dust. After fermentation with probiotics by Lactobacillus acidophilus that acidic conditions for 48 hours of infection with L. acidophilus increased from 2.02 × 105 CFU/g to 3.5 × 105 CFU/g can prevent other microbes in dust contaminated corn. And study the conditions necessary for such a period of growth, moisture, carbon, nitrogen and compounds promote growth. The study found that as that a period 48 hours. Moisture starting at 60 percent, the amount of carbon source from molasses dissolved in water (1:20) is 15 percent (w/w), nitrogen source from ammonium sulfate was 1.0 percent (w/w) , and substances promote growth from yeast extract 1.5 percent (w/w) . After marinated with probiotics volume carotenoid high of 62.63 micrograms per gram weight dried corn dust
