The purpose of the study was to determine if pomegranate (Punica granatum L.) peel contains polyphenolic compounds with antibacterial activity against Cronobacter sakazakii. Minimum inhibitory and bactericidal concentrations a methanolic extract were found increase significantly (P < .05) decreasing temperature (37, 21, 10 °C) pH (6.0, 5.0, 4.0). Chemical analysis by high pressure liquid chromatography revealed that elligitannins α- β-punicalagin most abundant hydrolysable in extract,...
The present study aimed to characterize the physical properties of nanoemulsion-based sodium alginate edible coatings containing myrtle (Myrtus communis L.) essential oil and determine its inhibitory effects on Listeria monocytogenes in fresh Kasar cheese during 24-day storage at 4 °C. GC-MS analysis showed that main components were 1,8-cineol (38.64%), α-pinene (30.19%), d-limonene (7.51%), α-ocimene (6.57%). Myrtle an effect all tested L. strains this significantly increased after...
Cronobacter sakazakii is an opportunistic food-borne pathogen that causes severe infections with high morbidity and mortality rates in neonates, the elderly, immunocompromised individuals. The plant extracts containing natural antibacterial compounds are currently under consideration as alternatives to synthetic artificial preservatives for control of C. sakazakii. There has been increasing interest using plant-derived antimicrobials combination mild heat pathogens preservative-free foods....
The thermal tolerance Cronobacter sakazakii was examined in sterile powdered infant formula (PIF) rehydrated at 58 °C water or apple juice supplemented with vanillin, ethyl vanillic acid. All three compounds decreased during-rehydration and the lowest decimal reduction time (D-value, 0.19 ± 0.01 min) measured PIF 20 mM At this level of supplementation no C. were detected stored for 48 h 10 24 21 subsequent to a sublethal heat treatment. Thermal during rehydration survival reconstituted...
A modified selective medium (modified Cetrimide Agar, mCA) consisting of 200 μg/mL benzalkonium chloride (BKC) was developed for the isolation Pseudomonas aeruginosa from raw milk. Initially, a total 55 isolates were obtained 14 milk samples collected several dairy plants in Ankara, Turkey. Among these isolates, 19 identified as aeruginosa, 28 fluorescens, 4 Acinetobacter baumannii, 2 Enterobacter intermedium, 1 asEnterobacter agglomerans, and Escherichia coli using Microbact biochemical...
Bu calismada farkli konsantrasyonlarda (%1, 2, 3, 4 ve 5) mercankosk ( Oreganum heracleoticum L. ) bahce kekigi Thymus vulgaris L .) ucucu yagi ilave edilerek hazirlanmis izole soya proteini bazli yenilebilir filmlerin Listeria monocytogenes , Salmonella Enteritidis Bacillus cereus uzerine antimikrobiyel etkileri belirlenmistir. Mercankosk iceren minimum konsantrasyonda (%1 w/v) tum test bakterilerine karsi etkin antibakteriyel aktivite gosterdigi, kekik icermeyen kontrol filmlerinin ise...
Cronobacter spp., bebeklerde ve cocuklarda hayati tehlike yaratan menenjit, sepsis nekrotizanenterokolit enfeksiyonlarinin onemli bir sebebidir. Cesitli klinik vakalarda spp. enfeksiyonuile bebek mamasi tuketimi epidemiyolojik olarak iliskili bulunmustur. Bu arastirmada mamasindapatojenin hizli tanisi icin direkt PCR yontemi uzerine modifikasyon calismalari yapilmistir. Bebekmamasinda ile 102KOB/mL duzeyinde 4 saatlik on zenginlestirme sonrasindauygulanan 1 KOB/mL seviyesinde...
Bu araştırmada, vanilin ve nisinin ılımlı sıcaklık koşullarında Listeria monocytogenes inaktivasyonu üzerine etkisi yanıt yüzey yöntemi ile incelenmiştir. L. inhibisyonunda konsantrasyonu (0.5–1.5 mg/mL), nisin (5–10 IU/mL), (45–55C) süre (2–6 dak.) bağımsız değişkenlerinin etkisini belirlemek için merkezi kompozit tasarımı kullanılmıştır. Elde edilen ikinci dereceden model ile, konsantrasyonu, sıcaklığın inhibisyon önemli bir etkiye sahip olduğu buna karşın sürenin ise önemsiz...
