“…The studies published so far have addressed two different procedures: LAB cells produced in MRS broth and analyzed for aflatoxin adsorption capacity in buffer solution, as shown by Oatley et al (2000), Lahtinen et al (2004), Shahin (2007) or Fazeli et al (2009); or, aflatoxin adsorption assays were performed directly in the dairy product, for example, in milk samples, but in this case, the adsorption of aflatoxin M 1 , an 4-hydroxylated metabolite derivative from AFB 1 biotransformation in the liver of animals that had been fed with contaminated diet, was performed, as shown in studies of Pierides et al (2000), Sarimehmetoglu & Küplülü (2004), Elgerbi et al (2006) and Bovo et al (2013).…”

“…The L. rhamnosus cells produced in MRS broth or MMW were inactivated by sterilization (121 °C, 15 minutes) because even non-viable cells are able to adsorb the AFB 1 (Bovo et al, 2013). The AFB 1 binding assays were conducted using the method described by El-Nezami et al (1998) with some adaptations.…”

“…Eighteen different types of aflatoxins have been identified so far, and aflatoxin B 1 (AFB 1 ) is the most prevalent and toxic metabolite produced by the fungi (Bhat et al, 2010). Several studies have demonstrated the efficiency of different species and strains of LAB in adsorbing aflatoxins from contaminated media (El-Nezami et al, 1998;Pierides et al, 2000;Oatley et al, 2000;Haskard et al, 2001;Peltonen et al, 2001;Azab et al, 2005;Fazeli et al, 2009;Bovo et al, 2013).…”

IntroductionAflatoxins are secondary metabolites produced by molds that have carcinogenic, mutagenic, and teratogenic effects on humans and animals (1-3). Among the aflatoxins, aflatoxin B 1 (AFB 1 ) is one of the strongest known hepatocarcinogens and is classified as a category 1A carcinogen by the International Agency for Research on Cancer (4). Due to their importance in showing these effects in the consumption of contaminated foods, there is a serious effort made by the food industry to make products safe. Moreover, considering the tendency of consumers to prefer natural products because of the worry about possibly hazardous food additives, both researchers and producers are taking responsibility to investigate new ways as an answer to the consumer expectations.Although the different methods used at present are to some extent successful, they have major disadvantages with limited efficacy, possible losses of important nutrients, and normally high costs. Many workers in the field are of the opinion that the best solution for decontamination should be detoxification by biodegradation, giving a possibility for removal of mycotoxins under mild conditions without using harmful chemicals and without significant losses in nutritive value and palatability of decontaminated food and feed (5). A number of studies have found that some microorganisms, especially lactic acid bacteria, break down or bind to aflatoxins. Researchers have obtained different results in these studies conducted to investigate the in vitro aflatoxin binding/degradation effect of lactic acid bacteria (6-9). Zinedine et al. (10) indicated that the toxin binding level changes in some environmental conditions having different pH and temperature. Supporting this finding, Haskard et al. ( 7) also found that environmental conditions, acid and heating applications, and the structure of the bacteria had an important effect on the stability of the toxin-bacteria complex. In another study, Kabak (11) showed that the aflatoxin B 1 binding capability of probiotic lactic acid bacteria varied in vitro, and in food had 32%-46.5% of the in vitro toxin binding rate. Fuchs et al. (12) found that the effectiveness of lactic acid bacteria in detoxifying ochratoxin and patulin was affected by toxin concentration, cell density, pH of the environment, and whether the cells were viable. Based on these and similar results, Hernandez-Mendoza et al. (13) suggested that lactic acid bacteria bound the toxins to different extents depending on the environment and the amount of bile salt present.Another challenge for researchers is achieving the same good results when lactic acid bacteria are applied to food. First of all, certain temperatures and pH levels must be provided; otherwise, the microorganisms would not show their effects. Probably, a higher number of bacteria would

“…In reference [50] it was observed that heat-treated cells removed greater percentages of AFM 1 (12.4% to 45.7%) in PBS compared with viable cells (5.6% to 33.5%), with no significant differences between 15 minutes or 24 hours of contact. Similar results were found in [51], because viable cells of Lactobacillus delbrueckii spp.…”
