Destruction of Yersinia enterocolitica by Lactobacillus sake and Pediococcus acidilactici During Low-temperature Fermentation of Turkish Dry Sausage (sucuk)
نویسنده
چکیده
Effects of starter cultures, Lactobacillus sake and Pediococcus acidilactici, on the survival of Yersinia enterocolitica were studied in Turkish dry sausage (sucuk). Inoculated Y. enterocolitica (approximately 5.0 log CFU/ g) was eliminated completely in sausages by L. sake (about 7.0 log CFU/g) and P. acidilactici (about 7.0 log CFU/g) by the 3rd d of fermentation but was not totally eliminated in natural fermentation without starter(s) after completion of 4 d of fermentation and 12 d drying (p 0.05). pH decreased from 6.3 to about 4.7 in starter culture treatments and from 6.3 to 5.6 in natural fermentation after completion fermentation and drying (p 0.05).

Members of the bacterial population of two types of Portuguese dry smoked sausages (chouriços) were identified and characterized. A total of 77 isolates were recovered from chouriços type Alentejano and Ribatejano, after 120 days at 20 ± 5 oC in modified atmosphere package (55 % N2/45 % CO2) using non-selective and selective media. Based on phenotypic (cell morphology and fermentation profile) ...

The pulsed-field technique of clamped homogeneous electric field electrophoresis was employed to characterize and size genomic DNA of three pediocin-producing (Ped+) and two non-pediocin-producing (Ped-) strains of Pediococcus acidilactici. Comparison of genomic fingerprints obtained by digestion with the low-frequency-cleavage endonuclease AscI revealed identical restriction profiles for four ...
