Surface microflora of four smear-ripened cheeses.
The microbial composition of smear-ripened cheeses is not very clear. A total of 194 bacterial isolates and 187 yeast isolates from the surfaces of four Irish farmhouse smear-ripened cheeses were identified at the midpoint of ripening using pulsed-field gel electrophoresis (PFGE), repetitive sequence-based PCR, and 16S rRNA gene sequencing for identifying and typing the bacteria and Fourier tra...
متن کاملModeling the growth of Listeria monocytogenes on the surface of smear- or mold-ripened cheese
Surface-ripened cheeses are matured by means of manual or mechanical technologies posing a risk of cross-contamination, if any cheeses are contaminated with Listeria monocytogenes. In predictive microbiology, primary models are used to describe microbial responses, such as growth rate over time and secondary models explain how those responses change with environmental factors. In this way, prim...
متن کاملFirst Identification of Two Potent Thiol Compounds in Ripened Cheeses
Different methods of sample preparation followed by extractions with phydroxymercuribenzoate (pHMB) were used to investigate the occurrence of thiol compounds in ripened cheeses. The analysis of cheese extracts by GC coupled with PFPD, MS and olfactometry detections enabled the identification of ethyl 2mercaptopropionate (ET2MP) and ethyl 3-mercaptopropionate (ET3MP) in Munster and Camembert ch...
متن کاملGrowth Reduction of Listeria spp. Caused by Undefined Industrial Red Smear Cheese Cultures and Bacteriocin-Producing Brevibacterium linens as Evaluated In Situ on Soft Cheese
The undefined microbial floras derived from the surface of ripe cheeses which are used for the ripening of commercial red smear cheeses have a strong impact on the growth of Listeria spp. In some cases, these microbial consortia inhibit Listeria almost completely. From such undefined industrial cheese-ripening floras, linocin M18-producing (lin) (N. Valdés-Stauber and S. Scherer, Appl. Environ....
متن کاملControl of Listeria monocytogenes growth in soft cheeses by bacteriophage P100
The purpose of this study was to determine the effect of bacteriophage P100 on strains of Listeria monocytogenes in artificially inoculated soft cheeses. A mix of L. monocytogenes 1/2a and Scott A was inoculated in Minas Frescal and Coalho cheeses (approximately 10(5) cfu/g) with the bacteriophage added thereafter (8.3 × 10(7) PFU/g). Samples were analyzed immediately, and then stored at 10 °C ...
