Abstract
The objective of the research study was to determine the effectiveness of the Staphylococcus carnosus ATCC–51365 bacterial strain in respect of the reduction of nitrates(V) in meat. The research material comprised the strain of Staphylococcus carnosus ATCC–51365 denitrifying bacteria isolated from dried sausages. The effectiveness of those bacteria in respect of the reduction of nitrates(V) was studied in a model forcemeat with sodium nitrate(V) added at a level of 100 mg/kg of. In the research study, two methods of multiplying bacteria strains were compared. The first method was used to conventionally multiply bacteria on a TSB protein medium. The second method consisted in that bacteria were multiplied on a TSB medium and, additionally, the bacterial cells were stimulated by sodium nitrate(V) added at a specific level into the medium. On the basis of the research study performed, it was found that the multiplication method of Staphylococcus carnosus ATCC–51365 strain had a significant effect on the activity of those bacteria in respect of the reduction of nitrates(V) in the heat-treated forcemeat. In the case of the variant with the stimulation of bacterial cells during their multiplication, the strain discussed was characterized by a high activity already during the first stage of heat treatment (20 oC). A 100 % reduction of nitrates(V) was reported at the end of the treatment stage completed at a temperature of 45 oC. In the case of the strain multiplied conventionally, no activity was reported of bacteria as regards the reduction of nitrates(V) in forcemeat at a temperature of 20 oC.
