Biodegradation of Aflatoxin B1 by Lactic Acid Bacteria Isolated from Moromi

Aflatoxin B1 (AFB1) is one of the important mycotoxins found in foods from tropical countries like Indonesia. Detoxification would be the important strategy to reduce or eliminate AFB1 since aflatoxins are relatively resistant to common processing conditions. Soy sauce, an Indonesian fermented product, is prepared in two steps. First step is mold fermentation by Aspergillus oryzae and A. sojae to produce “koji”, while second step involves “brine” or “moromi” fermentation by the salt tolerant lactic acid bacteria and osmofilic yeast. The lactic acid bacteria and osmophilic yeast have been reported to have the ability to decrease the concentration of AFB1 (El-Nezami et al., 2000). The objective of this study was to investigate the ability of salt tolerant acid-producing microorganisms from moromito degradateAFB1.

    aflatoxin B1 is the most common in moldy food, its toxicity and carcinogenicity is also strongest.
