Abstract

Jedna je od općenitih značajki prokariota velika raznolikost genoma, na što utječu mutacije, horizontalni prijenos gena, prisutnost bakteriocina i bakterijskih virusa. Iznimna se genomska raznolikost razvila kao posljedica izlaganja mikroorganizama stresu i njihove prilagodbe različitim uvjetima okoliša. U radu su predstavljena dva primjera raznolikosti prokariota: genetska varijabilnost jedinki vrste Escherichia coli i raznolikost mikroorganizama prisutnih u slanim staništima, praćena raspravom o zdravstvenim problemima uzrokovanim unosom kontaminirane hrane i mogućnosti primjene mikroorganizama u biotehnologiji.
