A study was carried out to select suitable bacterial cultures for the production of dry fermented sausages. Micrococcus roseus (MTCC-1532), Lactobacillus plantarum (MTCC-1407 and L-89) and Pediococcus acidilactici (NCIM-2292 and NCIM-2293) were tested for their growth in the presence of sodium chloride, sodium nitrite, sodium nitrate and at various temperatures. Their ability to ferment sugar was also assessed. These hurdles were used alone and in combination. It was observed that M. roseus (MTCC-1532), L. plantarum (MTCC-1407) and P. acidilactici (NCIM-2293) were able to show very good growth in presence of salts and were suitable for use as starter cultures in production of dry fermented sausages.
