This study reports on the evaluation of the antioxidant of ethanolic extracts of Mytilus galloprovincialis and Ruditapes philippinarum collected from the Marmara Sea. The antioxidant activity of the two bivalve species was evaluated using the 2,2-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging method. The total carotenoid contents were also determined. In the DPPH method, all extracts exhibited low radical scavenging activity when compared to the standards used, i.e. -tocopherol and butylated hydroxytoluene (BHT) with the inhibition percentage in the range of 35.87±0.05 – 36.27±0.02%. In particular, M. galloprovincialis exhibited the highest radical scavenging activity with an IC50 value of 29.55±0.02 mg/g Ext. However, there are no statistically significant differences in the IC50 values of two species. The highest total carotenoid content was found in M. galloprovincialis as 1.13±0.02 µg/g sample. The statistically significant differences were found in total carotenoid contents of two bivalves. In this study in M. galloprovincialis was also found to be high in carotenoid content, while R. philippinarum was found to be almost nonexistent. More detailed studies are needed to determine relationship between the bioactive compounds of crustaceans and their antioxidant activities, distributed in our country.

According to World Health Organization (WHO), an estimated 600 million people fall ill after eating contaminated food and 420 000 die every year. Although various foods can serve as sources of foodborne illness, meat has been at the forefront of societal concerns in recent years. Meat is source of some foodborne pathogens which have an important role on human health. In this study, it was aimed to examine the microbiological quality of raw bovine meat samples sold in Tokat province and to evaluate the results in the context of food safety. For this purpose, 18 raw meat samples purchased from butchers and markets were analyzed for total mesophilic aerobic bacteria, total psychrophilic aerobic bacteria, yeasts-molds, lactic acid bacteria, B. cereus, S. aureus, C. perfringens, total coliform, and fecal coliform. The presence of E. coli, E. coli O157:H7, L. monocytogenes and Salmonella spp. were also investigated in these samples. The lowest and highest values determined for the parameters were as follows: total mesophilic aerobic bacteria 1.46×104-1.26×107 CFU/g, total psychrotrofic aerobic bacteria 1.01×104-2.65×106 CFU/g, yeasts-molds 3.00×103-1.70×104 CFU/g, lactic acid bacteria 2.70×103-3.60×104 CFU/g, B. cereus ˂102-7.20×104 CFU/g, S. aureus 2.60×103-2.57×105 CFU/g, C. perfringens ˂102-9.20×103 CFU/g, total coliform 3.80×101-2.90×104 MPN/g, and fecal coliform

Over the years, the growing concerns about the negative impact of anti-microbial growth promoters has triggered researches into the use of phytogenic feed additives in poultry production in order to ascertain better performance of birds as well as safety in the food chain. Phytogenic feed additives are compound derived from varieties of plants, its parts, extracts and essential oils which possess active substances that are of significant importance. Some of its functions include anti-microbial and anti-oxidative effects on the poultry feeds and carcass as well as enhancement of flavour of feeds. Despite the beneficial influences of PFAs, numerous controversial issues have emerged on the appropriate dosage to be used in poultry production. This may be due to the differences in edaphic and climatic actions on plants available in various part of the world and stage of harvesting of plants which makes standardizing inclusion levels of phytogenic feed additives in poultry diet seemingly difficult. However, it is crystal clear that phytogenic feed additives qualify as a better substitute to anti-microbial growth promoters as it is safe and ecologically friendly.

Sainfoin (Fabaceae) is one of the most critical animal forage crops. However, the tolerance of sainfoin is low against to salinity. This study aims to investigate biochemical responses of the shoot and root tissue of sainfoin seedlings to moderate salt stress under in vitro conditions. For this aim, the seed of sainfoin were sown MS medium containing 100 mM NaCl. Antioxidant enzymes (CAT, SOD, APX, and GR), proline and malondialdehyde (MDA) contents were measured in shoot and root tissue of 35-day-old seedlings of sainfoin. A significantly higher constitutive catalase (CAT) and superoxide dismutase (SOD) activity was observed in shoot tissues when compared to root tissues. Overall, salt stress caused significant more enhancement in the activity of antioxidant enzymes (CAT, SOD, APX, and GR) in shoot tissues than root tissue. On the other hand, among the antioxidant enzymes, SOD seems to be more active in both tissues of sainfoin. Interestingly, the activity of GR reduced in both tissue under salt stress. The content of proline and MDA has been increased under salt stress and this increase has been more in the root tissue. This study has revealed biochemical responses to salt stress in different organs of sainfoin.

Kurşun (Pb), belirli eşik konsantrasyonları aştığında insanlar, hayvanlar ve bitkiler için tehlikeli olan bir ağır metaldir. Tütün bünyesinde yüksek konsantrasyonlarda kurşun biriktirebilen bir bitkidir. Kurşun alımında tütün genotipleri arasındaki farklılıklar ve bitkilerin kurşuna verdikleri henüz cevap açıkça belirlenmemiştir. Bu çalışmanın amacı, Pb dozlarının (Pb 0; 0,25; 2,5 ve 10 mg kg-1) iki farklı tütün çeşidinin (Xanthi/2A ve Nail) biyomas (kök ve yeşil aksam) üretimi, Pb konsantrasyonu ve mikro besin konsantrasyonları üzerindeki etkilerini belirlemektir. Kontrollü koşullar altında yetiştirilen tütün çeşitlerine artan Pb dozları ile birlikte temel makro (N, P ve K) ve mikro (Fe ve Zn) besin elementleri verilmiştir. İki farklı tütün çeşidinde biomas üretimi (kök ve yeşil aksam kuru madde verimi), yeşil aksam Pb, Zn, Fe, Mn ve Cu konsantrasyonları belirlenmiştir. Artan dozlarda Pb uygulaması ile çeşitlerin kuru madde verimi önemli ölçüde etkilenmiştir. Kök ve yeşil aksamda ortaya çıkan azalmaya karşın, artan dolarda kurşun uygulamaları ile tütün çeşitlerinin yeşil aksam kurşun konsantrasyonlarında istatiksel olarak önemli artışlara neden olduğu ortaya çıkmıştır. Artan dozlarda Pb uygulaması ile tütün çeşitlerinin yeşil aksam Zn, Fe, Mn ve Cu konsantrasyonlarında istatiksel olarak önemli artış ve azalışlara neden olduğu ortaya çıkmıştır. Sonuç olarak en yüksek kurşun dozunda dahi Nail ve Xanthi/2A tütün çeşitlerinin yeşil aksamında 1,0 mg kg-1’ın altında Pb konsantrasyonuna sahip olduğu ortaya çıkmıştır. Buna rağmen kurşun ile kirlenmiş topraklarda yetişen tütün çeşitleri ile yapılan tütün mamulleri insanlar içim risk teşkil etmektedir.
