Fungal metabolites including regulated mycotoxins were identified by a validated LC-MS/MS method in 180 individual Turkish dried figs from 2017 and 2018 harvests. Hand-selected dried figs were subjectively classified based on the extent of fluorescence. Forty-three fungal metabolites including eight EU-regulated mycotoxins were identified and quantified. Figs classified as being uncontaminated mostly did not contain aflatoxins above 1 mu g/kg. Despite being "uncontaminated" from an aflatoxin perspective, kojic acid was present in significant quantities with a maximum level of 3750 mg/kg (0.375% w/w) and tenuazonic acid was also found (2 mu g/kg to 298 mg/kg) in some figs. Notable in the screening of figs has been the presence of significant amounts of aflatoxin M-1(AFM1) in figs also containing significant levels of aflatoxin B-1(AFB1), which is the first time that AFM1 has been reported as naturally occurring in dried figs.

Analysis of the genetic determinant for production of the pediocin P of Pediococcus pentosaecus Pep 1 Osmanagaoglu, O; Beyatli, Y; Gündüz, Ufuk; Sacilik, SC (2000-01-01) Pediococcus pentosaceus Pep1 is a vacuum-packaged Turkish sausage isolate which produces a potentially novel bacteriocin of the pediocin (anti-Listeria) family of peptides designated as pediocin P. Curing experiments and plasmid profile analysis indicated that both bacteriocin immunity and production determinants were linked and encoded by 9.0 MDa plasmid, pHD1.0. Attempts to transform purified plasmid pHD1.0 into recipient Escherichia coli JM109 cells by electroporation were successful but none of the E. c...
CHANGES IN PATTERNS OF ALKALINE SERINE PROTEASE AND BACILYSIN FORMATION CAUSED BY COMMON EFFECTORS OF SPORULATION IN BACILLUS-SUBTILIS-168 BASALP, A; Özcengiz, Gülay; ALAEDDINOGLU, NG (Springer Science and Business Media LLC, 1992-03-01) Bacilysin biosynthesis and alkaline serine protease production in Bacillus subtilis 168 were monitored and compared in batch cultures when various effectors of sporulation were added at different stages of growth in a medium containing sucrose and glutamate. Depending on the time of addition, glucose affected sporulation and serine protease formation to the same extent, but had no effect on bacilysin production. Ammonium and L-alanine additions suppressed all three processes. Casamino acids severely interfe...
Functional analysis of a mirna putatively involved in powdery mildew disease susceptibility in barley Dağdaş, Gülay; Akkaya, Mahinur S.; Department of Biotechnology (2009) Barley is one of the most important crop species in Turkey and powdery mildew is one of the most common pathogen decreasing yield in barley. For this problem, agricultural biologists apply breeding technologies in order to select and propagate resistant barley cultivars. However, this is not a permanent solution since pathogens evolve rapidly to overcome plant resistance mechanisms. On the other hand, molecular plant pathologists are trying to understand basic mechanisms underlying plant-pathogen interactio...
Identification and killer activity of a yeast contaminating starter cultures of Saccharomyces cerevisiae strains used in the Turkish baking industry Izgu, F; Altinbay, D; Yucelis, A (Elsevier BV, 1997-04-01) The yeast contaminating the starter cultures of Saccharomyces cerevisiae fermentation strains BSP 1-4, used in the Turkish baking industry, was identified as Candida tropicalis with a killer phenotype. The activity of the killer toxin against the industrial strains was optimum at pH 3.9 and 4.1 at 22-25 degrees C. The activities of some killer toxin-producing yeasts of known phenotypes against C. tropicalis were determined. Among the yeasts tested S. cerevisiae K3 and Hansenula anamola K8 were inhibitory to...
Levels, Distribution, and Sources of Polychlorinated Biphenyls in Sediments of Lake Eymir, Turkey Gedik, Kadir; İmamoğlu, İpek (Springer Science and Business Media LLC, 2013-08-01) Little information is available on the occurrence and fate of persistent organic pollutants in lakes of Turkey. The present study was performed as a first step to assess the occurrence, spatial distribution, and potential sources of polychlorinated biphenyls (PCBs) in surface sediments of Lake Eymir located in a special protection area. I 41PCB pound concentrations range from 1.09 to 2.33 ng g(-1) in 62 sediment samples collected from the lake. The spatial homogeneity of the PCBs along the whole lake sugges...
