Nonconventional starter cultures of coagulase-negative staphylococci to produce animal-derived fermented foods, a SWOT analysis

Coagulase-negative staphylococci (CNS) are ubiquitous micro-organisms that are commonly present on animal skin and animal-derived foods. They are members of the beneficial microbial consortia of several fermented food products where they contribute to quality. Currently, only a few CNS species are included in commercial starter cultures, although many other ones with promising properties have been isolated from diverse food ecosystems. In the present study, a Strengths-Weaknesses-Opportunities-Threats (SWOT) analysis of the potential use of unconventional CNS starter cultures for the fermentation of animal-derived foods is carried out. An overview of both their desirable and worrisome metabolic traits is given. In general, the application of innovative CNS-based starter cultures offers opportunities to modulate flavour, improve the safety and health aspects and develop novel colour development strategies for clean label products. Yet, their implementation is often not straightforward as nontrivial obstacles or threats are encountered, which relate to technological, food safety and legal concerns. As most of the desirable and undesirable characteristics of CNS species are strain dependent, a case-by-case evaluation is needed when evaluating specific strains for their potential use as novel starter cultures.

“…In our previous antibiotic resistance test of 126 S . equorum strains, two strains showed independent ciprofloxacin and ofloxacin resistance and both strains also exhibited multidrug resistance 14 . Their quinolone resistance might be an acquired trait and the chromosomal quinolone resistance homologs may be weakly related to the phenotypic quinolone resistance of S .…”

To shed light on the genetic background behind the virulence and salt tolerance of Staphylococcus equorum, we performed comparative genome analysis of six S. equorum strains. Data on four previously published genome sequences were obtained from the NCBI database, while those on strain KM1031 displaying resistance to multiple antibiotics and strain C2014 causing haemolysis were determined in this study. Examination of the pan-genome of five of the six S. equorum strains showed that the conserved core genome retained the genes for general physiological processes and survival of the species. In this comparative genomic analysis, the factors that distinguish the strains from each other, including acquired genomic factors in mobile elements, were identified. Additionally, the high salt tolerance of strains enabling growth at a NaCl concentration of 25% (w/v) was attributed to the genes encoding potassium voltage-gated channels. Among the six strains, KS1039 does not possess any of the functional virulence determinants expressed in the other strains.

“…Gram staining, catalase, and coagulase test results showed that among the 67 selected colonies, a total of 61 were Gram‐positive, catalase‐positive, and coagulase negative cocci. In previous studies exhibited that Gram‐positive, catalase‐positive, and coagulase negative cocci are associated with traditional fermented sausages produced in Europe (Bonomo, Ricciardi, Zotta, Sico, & Salzano, ; Cachaldora, Fonseca, Franco, & Carballo, ; Kaban & Kaya, ; Kesmen, Yarimcam, Aslan, & Yetim, ; Landeta et al, ; Marty et al, ; Mauriello, Casaburi, Blainotta, & Villani, ; Resch, Nagel, & Hertel, ; Zdolec et al, ), as confirmed in this study.…”

The aim of this research was to detect antibiotic susceptibility patterns and amino acid decarboxylase activity of 61 presumptive coagulase‐negative Staphylococcus (CNS) strains from the Turkish dry fermented sausage (sucuk). The presumptive CNS strains were identified at species levels as 21 S. saprophyticus, 16 S. epidermidis, 10 Macrococcus caseolyticus, 4 S. xylosus, 3 S. sciuri, 2 S. hominis, 2 S. warneri, 1 S. cohnii, 1 S. pasteuri, and 1 S. vitulinus by 16S rDNA sequence analysis. S. saprophyticus and S. epidermidis species were found highly resistant to antibiotics than other species. In addition, most of the CNS and M. caseolyticus strains showed multiple antibiotic resistance profiles. None of the CNS and M. caseolyticus strains did not decarboxylate histidine, lysine, or ornithine, but only three CNS strains produced tyramine from tyrosine. A 100% correlation was found between the presence of tdc gene and tyramine production in tyraminogenic strains. Practical applications Coagulase‐negative Staphylococcus (CNS) strains play an important role in production of traditional fermented sausages such as sucuk. In this study, S. saprophyticus and S. epidermidis were found the most common isolated CNS species from sucuk. Antibiotic resistance was detected widespread in CNS and M. caseolyticus strains. Most of the CNS strains were found resistant to clinically relevant antibiotics. Antibiotic resistance strains may be dangerous for consumer health. These strains can be a potential reservoir to spread of antibiotic resistance gene between staphylococci and other species of bacteria. In addition, biogenic amine production was not found widespread in CNS strains.
