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 supe...

Petroleum refining industries produce large amounts of toxic effluents, causing environmental pollution. Iran is an oil-rich country that encounters oil pollution in its soil and water. Bioremediation of these pollutants is an appropriate solution to tackle them, compared to physical and chemical remediation methods. There are some factors that increase the rate of biodegradation; therefore, th...

Nodule bacteria (rhizobia) in symbiotic associations with legumes enable considerable entries of biologically fixed nitrogen into soil. Efforts are therefore made to intensify the natural process of symbiotic nitrogen fixation by legume inoculation. Studies of field populations of rhizobia open up the possibility to preserve and probably exploit some indigenous strains with hidden symbiotic or ...

the purposes of this research were to the evaluation of resistance to nickel and cadmium in 52 indigenous and non-indigenous strains of contaminated soils and a study of growth promoting characteristics of some resistant isolates. resistance test at three levels of cadmium (0, 100, 200 mg l-1) and five levels of nickel (0, 250, 500, 750, 1000 mg l-1) in the framework of a completely randomized ...

conclusions the current study indicated that the immunoreactivity of secretory iga might have no direct correlation with the colonization of indigenous flora and rejection of exogenous strains in adults. the relationship of microbes, host and dental caries should be in the light of coevolved microecosystem as a whole, but not caused by one factor alone. results the results showed that naturally...

Two Saccharomyces cerevisiae strains were tested as the starter yeasts in a traditional cachaça distillery. The strains used were S. cerevisiae UFMG-A829, isolated from a cachaça fermentation process, and S. cerevisiae K1V1116, obtained from the wine industry. The permanence of each strain in the fermentation must was determined by RAPD (Random Amplified Polymorphic DNA)-PCR, with primer M13. B...

Our work has focused on the determination of physiological traits that may facilitate in situ degradation of xenobiotic compounds by indigenous microorganisms. For this our interests center on the following questions: What are the ambient conditions in a benzene, toluene, ethylbenzene, and xylene (BTEX)-contaminated aquifer? What is the behavior of indigenous bacteria under these conditions? Wh...
