Title: Integrated process for ammonia inactivation of aflatoxin-contaminated corn and ethanol fermentation

Abstract

A process is described for converting aflatoxin-contaminated corn to ethanol via combining ammonia inactivation with the liquefaction step of the ethanol fermentation process. Better ethanol yields were obtained when ammonia was added during liquefaction than when no ammonia was added. Aflatoxin B/sub 1/ levels were reduced 80 to 85% by the process.

  • Two lots of corn naturally contaminated with fumonisin B{sub 1} (15 and 36 ppm) and a control lot (no fumonisin B{sub 1} detected) were used as substrates for ethanol production in replicate 8.5-liter yeast fermentations. Ethanol yields were 8.8% for both the control and low-fumonisin corn, while the high-fumonisin corn contained less starch and produced 7.2 % ethanol. Little degradation of fumonisin occurred during fermentation, and most was recovered in the distillers' grains, thin stillage, and distillers' solubles fractions. No toxin was detected in the distilled alcohol or centrifuge solids. Ethanol fermentation of fumonisin-contaminated corn coupled with effective detoxification ofmore » distillers' grains and aqueous stillage is suggested as a practical process strategy for salvaging contaminated corn.« less
  • Aflatoxins, the toxic secondary metabolites of Aspergillus flavus and Asp. parasiticus, constitute a serious food contamination problem in Nigeria and have been detected in the blood of healthy rural blood donors and primary liver cancer patients from the Guinea savannah region where traditionally brewed cereal beer is popular. A recent survey of traditional breweries in the Jos metropolis has shown a high incidence of aflatoxin B/sub 1/ contamination of their products. The purpose of this study was to assess the efficiency of the traditional brewing in destroying aflatoxins in mould-infected substrate grains.
  • The production of solvents from corn mash and molasses in batch fermentation using Clostridium acetobutylicum P 262 was examined. The content of saccharose of beet molasses used in experiments is determined by using the gravimetric method (52.45% saccharose). The quantities of molasses that are used in the nutrient medium are calculated after doing the above determination. The samples of fermentation liquid are taken within a certain time, the determination of saccharose is done by using the same method, and all the saccharose is converted by the microorganism to organic end products. The quantitative and qualitative determination of acetone-butanol has beenmore » made by using gas chromatography. On the other hand, using the three isolation way, three different cultures are obtained, and with microscopic observations, the cultures obtained are of the C. acetobutylicum genus. According to the literature values, the concentration of maximum mixed solvent formed during fermentation is about 2%. This is seen in this experiment. There is only a slight difference from this value. This difference is caused by another organic product that is formed during fermentation. 9 refs., 1 fig., 1 tab.« less
