Roles of bacteriocins in food safety

INTRODUCTION DEFINITION AND HISTORY Bacteriocins are bacterial ribosomally synthesized peptides or proteins with antimicrobial activity. As ribosomally synthesised peptides, bacteriocins are encoded by a plasmid- or chromosome-borne structural gene which is often clustered with genes coding for immunity protein(s) and dedicated transport. Bacteriocins are proteinaceous toxins produced as a tiny molecule by bacteria to inhibit the growth of similar or closely related bacterial strain(s) produc...

Mycotoxins: Characterization , Occurrence and Detection

INTRODUCTION Mycotoxins are pharmacologically active mold metabolites produced in a strain-specific way that elicit some complicated toxicological activities (Bennett, 2003). Mycotoxins could also be described as secondary metabolites produced by a wide variety of organisms categorized as fungi, including mushrooms, yeasts and molds. The term mycotoxin was used for the first time in 1961 in the aftermath of a veterinary crisis in England, during which thousands of animals died. The disease wa...

THE EFFECT OF ENVIRONMENT ON CORROSION

ABSTRACT In this research project, the various nail was subjected to six environments so as to check the effect of the environments on corrosion of the nails. Two sets of nails were used; normal nail and concrete nail.  Six of each type while the other not coated. The environments used are acidic solution, alkaline solution, salt solution, boiled water, air medium and lubricating oil medium, which served as a control medium. It was observed from the graphs of the weight of metal against time...

ISOLATION, IDENTIFICATION AND CLASSIFICATION OF FUNGI
