Article Citation - WoS: 1Analysis of Alicyclobacillus Acidoterrestris Spores From Different Sporulation Media Subjected To Wet-Heat(PagePress Publications, 2015) Molva, Çelenk; Baysal, Ayşe HandanThe presence of Alicyclobacillus acidoterrestris endospores in fruit juices is a significant problem for the juice industry since they are able to survive pasteurization subsequently leading to the spoilage. To evaluate the mechanism of wet-heat, structural damage and the leakages of intracellular materials of A. acidoterrestris DSM 3922 spores from different sporulation media was studied at 90 degrees C (15-45 min). For sporulation, Bacillus acidoterrestris agar, Bacillus acidocaldarius agar, potato dextrose agar and malt extract agar were used. Based on the scanning electron microscopy, loss of internal volume and structural integrity were observed following heating which were further confirmed by the leakages of intracellular components. The obtained results suggest that the inactivation of A. acidoterrestris DSM 3922 spores by wet-heat is associated with damage to the coat and inner membrane depending on the sporulation medium composition and heating time.Article Citation - WoS: 4Prevalence and Diversity of Arcobacter Spp. in Retail Chicken Meat in Turkey(PagePress Publications, 2016) Molva, Çelenk; Atabay, Halil İbrahimArcobacters are food and waterborne pathogens associated with human and animal infections. The objective of the present study was to investigate the prevalence and diversity of Arcobacter spp. in commercially sold chicken meat in Izmir region of Turkey. For this purpose, 100 samples including legs (n= 40), 17 chicken quarters (n= 17), drumstickers (n= 16), breasts (n= 11), wings (n= 10), and carcasses (n= 6) were collected from different retail markets. A total of 65 isolates were confirmed as Arcobacter spp. from 55 samples by genus-specific polymerase chain reaction (PCR). The prevalence of Arcobacter spp. was 32.5, 81.3, 64.7, 72.7, 83.3, and 50% for legs, drumstickers, chicken quarters, breasts, carcasses and wings, respectively. Based on the multiplex-PCR, most of the isolates were identified as A. butzleri (n= 45, 80%), followed by A. cryaerophilus (n= 2, 3.6%), A. skirrowii (n= 1, 1.8%) and 17 isolates (30.9%) could not be identified at the species level.
