Abstract

This  paper  aims  to  examine  the  isolation  of  Lactobacillus  from  dairy  products  (milk, curd,  and  yogurt),  extraction  of  Bacteriocin  from  it  as  well  as  to  determine  their inhibitory  effect  against  few  fungal  skin  pathogens  and  bacterial  skin  pathogens  such as:  Candida albicans,  Aspergillus sp.,  Malassezia sp.,  Fusarium sp.,  and  Penicillium sp., Staphylococcus aureus,  Streptococcus pyogens,  Klebsiella sp.  The antagonistic activity of Lactobacillus sp.  is  mainly  due  to  the  bacteriocin  present  in  it,  therefore  in  this  study, the  bacteriocin  is  extracted  and  checked  against  the  indicated  microorganisms.  Kirby Bauer  Disc  Diffussion  method  is  used  and  zone  of  clearance  is  observed  around  the pathogenic  species  indicating  that  they  shows  some  kind  of  antagonistic  activities  which are  further  measured  and  noted,  which  gives  a  clear  picture  about  the  degree  of  resistance  of  bacteriocin  against  the  pathogenic  microorganisms.
