چکیده مقاله:

This study was carried out to examine aflatoxin B1 (AFB1) removal ability of four strains of lactic acidbacteria (LAB). Three indigenous (Lactobacillus rhamnosus TMU094, Lactobacillus fermentum TMU121and Pedioccus pentosaceus TMU457) and a non-indigenous (Labacillus rhamnosus PTCC1637) isolateswere studied. The strains were incubated with (AFB1) at different time. The toxin residual in the supernatantwas determined. Reduction of the toxin quantity was observed by all species. Binding of aflatoxin by thestudied LAB varied from 19.41 to 75.06%. Aflatoxin-binding activity showed time dependent trend takinginto consideration of different incubation periods. Lactobacillus rhamnosus TMU094 bound 25.64 to75.06%, L. fermentum bound 38.63 to 72.15%, P. pentosaceus bound 24.86 to 63.21% and L. rhamnosusPTCC1637 bound 19.41 to 35% of AFB1 during the studied course of incubation times. These results showedthat indigenous strains of LAB are able to bind AFB1 effectively

A Study on the Antibacterial Activity of Lactic Acid Bacteria Isolated from Traditional Iranian Milk Samples

198 Lactic acid bacteria (LAB) were isolated from Iranian milk samples. Almost all isolatedLAB showed inhibitory activity towards E. coli and S. aureus as Gram negative and Grampositive indicators, respectively. No role was observed for hydrogen peroxide in the activity ofall isolated strains while organic acids proved a prominent role in all detected inhibitoryactivities. Within isolated LAB, ...

Decomposition and detoxification of aflatoxin B1 by lactic acid.

BACKGROUND A degradation study of aflatoxin B1 (AFB1) was carried out using a combination of physical and chemical methods. AFB1 was heated at 80 °C in the presence of acetic, citric and lactic acids for various time periods. The cytotoxicity of the degraded AFB1 and its products were determined by MTT assay. RESULTS The results showed that among the three organic acids lactic acid was most e...
