Novel leaderless bacteriocin geobacillin 6 from thermophilic bacterium .

Bacterial resistance to conventional antibiotics has urged us to develop alternative strategies against bacterial pathogens. Moreover, a demand for food products containing no chemical preservatives has led us to search for new alternative technologies for food preservation. Bacteriocins - ribosomally synthesized antimicrobial peptides - have been proposed as a new alternative to conventional antibiotics or chemicals for food preservation.
