Abstract

Dangke is one of traditional food from Enrekang Province Sulawesi Selatan which is made from buffalo milk and enzimatically processed using papain from papaya’s gland secretion. Research on this local product as source of lactic acid bacteria (LAB) has been done. Counted 30 LAB was successfully isolated and 3 of them were potentially to be able to yield antimicrobial compound. Enterococcus faecium DU55 is one of LAB isolate available to be applied for producing bacteriocin compound through fermentation. Optimum condition of fermentation was specified by determining the highest antimicrobial activity generated by filtrate of fermentation result. Antimicrobial activity examination was carried out through diffusion agar method by measuring inhibition zone growth of pathogen bacterium Salmonella typhimurium FNCC 0050. Research results indicate that maximum bacteriocin compound production by BAL isolate E. faecium DU55 was obtained at condition of optimum fermentation at 30 °C during 42 hour using M1 medium with the same composition to medium MRS (Man Rogosa and Sharpe).Keyword: dangke, LAB isolate, bacteriocin, antimicrobial activity

Abstract

Four different organic solvents, methanol, N- heksana, kloroform, and etil acetate were used to extracted some bioactive compounds from bark of mangroves plant Sonneratia alba (kayu buli) for screening of antibacterial activity against three pathogen bacteria, Staphylococcus aureus,Eschericha coli, and Bacillus subtillis by agar diffusion method. All extracts were able to inhibit the growth of these bacterial significantly in concentration of 5%. Etil acetate ekstract showed highest antibacterial activity.Methanol, chloroform, and etil acetate were effective solvent to extract bioactive compound that have a antibacterial properties from this plant.Keyword: Kayu buli, Sonneratia alba, antibacterial activity
