ASSESSMENT OF THE BACTERIOCINOGENICITY OF INDIGEN LACTOBACILLUS ONTO CATTLE CARCASSES

Cattle carcasses of ritual slaughter (Halal) from the lateral and medial side were investigated in order to identify the indigenous strains of lactic acid microorganisms capable of producing bacteriocins. Only 14 strains, from 36 strains of microorganisms isolated from washings taken from carcasses, were used for further research and identified as lactabacilus. In the study of their bacteriocinogenicity by the method of two-layer agars of modified composition, high inhibitory efficiency was proved with respect to the growth of the pathogen Salmonella typhimurium, only 6 isolated strains of lactabacilus. The use of this method of evaluation will not only reveal the presence of the ability of the lactabacilus to produce bacteriocins, but also to study their antagonistic activity against many of the studied microorganisms, which are indicators of compliance with various modes of technological processes. The presence of such microorganisms in the meat will increase the shelf life of meat, due to the suppression of the growth of closely related lactabacilus, some of which are spoilage microorganisms, as well as the growth of opportunistic and pathogenic microflora. In addition, the use of lactabacilus with bacteriocinogenicity in the production technology of raw sausages will reduce the risk of production of unsafe products. Thus, the presence of indigenous lactabacilus in meat is an additional factor that ensures the flow of desired biochemical processes and the safety of raw smoked sausages.
