This study aimed to evaluate two selected lactic acid bacteria strains, namely <em>Lactiplantibacillus plantarum</em> LWQ17 (LWQ17) and <em>Pediococcus pentosaceus</em> LWQ1 (LWQ1), on their antifungal activities and potential applications in CSB making. The results showed that both strains, especially LWQ17, displayed remarkable inhibition against <em>Aspergillus niger</em> and <em>Penicillium polonicum</em>, the representative species found in CSB spoilage. LWQ17 and LWQ1 destroyed the cell membranes of the fungi and caused a loss of intracellular substances. When applied in CSB making, both strains could delay the germination of mold on the surface of CSB in a season-dependent way. LWQ17 delayed the germination of mold by 4 d in Spring and Winter, while 1 d in Summer and Autumn. Further study revealed that their antifungal activities were greatly influenced by temperatures and humidity. Both strains could completely inhibit the germination of mold during two weeks of storage under 37 °C but with different humidity levels. Moreover, our results demonstrated that acidic substances were crucial in inhibiting the fungi, while proteinic substances and hydrogen peroxide played an auxiliary role. Analysis of their acids by targeted metabolomics showed that LWQ17 produced more kinds of acids, and the amount of phenyllactic acid produced by LWQ17 was 60 times higher than that produced by LWQ1, which may explain its better antifungal efficacy. This study provides a reference for employing lactic acid bacteria in CSB preservation under different conditions.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"168 ","pages":"Article 110940"},"PeriodicalIF":5.6,"publicationDate":"2024-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142438343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we isolated and identified a bacteriophage called vB_Kp_Z57 that targets K57 serotype <em>K. pneumoniae</em> isolates from human and bovine sources. The phage has a latent period of 4 min and can produce approximately 233 phages per infected bacterial cell. vB_Kp_Z57 is stable over a temperature range of 4 °C to 60 °C and a pH range of 5–11.

The results of bacteriostatic experiments show that vB_Kp_Z57 has a good effect on inhibiting bacterial growth.

To that end, a literature review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol, using specific key terms to identify relevant articles on food hygiene in SSA. Results showed that while there are variations across countries, the overall trend reveals that most catering services in the region do not meet critical hygiene standards.
