Keban Baraj Gölü ülkemizin en büyük ikinci baraj gölüdür. Bunun yanı sıra gerek su ürünleri potansiyeli gerekse elektrik üretimi açısından ülkemizin en önemli baraj göllerinden biri olma özelliğine de sahiptir. Bu çalışmada, Keban Baraj Gölü Örencik mevkiinden yakalanan Capoeta trutta balık örnekleri kullanılmıştır. Bazı ağır metallerin (bakır, demir, çinko, krom, nikel, kadmiyum, arsenic ve civa) Capoeta trutta’nın kas dokusundaki konsantrasyonları ile bu balığın insanlar tarafından tüketilmesi durumunda sağlık riski oluşturup oluşturmadığı araştırılmıştır. Ayrıca, ağır metal birikimi ile balığın bazı biyolojik özellikleri (ağırlık, uzunluk, cinsiyet) arasındaki ilişki de belirlenmiştir. Çalışma sonucunda Capoeta trutta’nın kas dokusunda en fazla birkim gösteren ağır metalin çinko, en az birikim gösteren ağır metalin ise kadmiyum olduğu tespit edilmiştir. Capoeta trutta’nın kas dokusundaki ağır metal konsantrasyonlarının balığın ağırlığına, uzunluğuna ve cinsiyetine bağlı olarak değişiklik gösterdiği bulunmuştur. Capoeta trutta’nın kas dokusundaki ağır metal düzeylerinin EPA, WHO ve FAO tarafından önerilen değerlerin altında olduğu, dolayısıyla bu balığın insanlar tarafından tüketilmesi durumunda sağlık riski oluşturmayacağı tespit edilmiştir.

The present study was conducted to determine the seed morphologies and macromorphological characteristics of fifteen local faba bean (Vicia faba L.) genotypes collected from different region of Northern Cyprus. The characteristics in the seeds were evaluated using a light microscope (LM) and scanning electron microscope (SEM). SEM pictures were taken of the whole seed and its details. The scope of the research was examined comparatively using LM and SEM, and the seed shapes, surface ornamentation, and quantitative measurements were determined. Different characteristics for seed size and surface were found among the local faba beans accessions. Seed dimensions were between 12.44 and 24.26 mm long and between 9.49 and 17.45 mm wide, colors ranged from yellowish-brown to dark brown, and ornamentation of the seed coat varied. The local faba bean seeds were of subprolate and prolate types. We believe that using this technique to determine the differences among the seeds of different genotypes may play a role in helping to create different programs that can choose specific genotypes to improve cultivars based on the seed characteristics.

Today, the honeybee parasite Varroa destructor is thought to be the most dangerous creature in the beekeeping industry worldwide. In this study, the efficacy of using drone brood cells (known to have no residue concerns in bee products and harmless on bee health) as traps against V. destructor was investigated. A total of 16 honeybee (Apis mellıfera) colonies with V. destructor infestation percentage of less than 5% were used for the trial. The treatment group consisted of 8 colonies that were randomly assigned to molded drone comb (comb with 5.4 mm hexagonal cells). The other 8 were assigned to unmolded comb to form the control group. In the trial groups, after 20 days (from 10th May), all drone combs with complete pupation were removed and destroyed on 30th May, 20th June, 10th July, 30th July, and 20th August. During the trial, varroa mite infestation rate (mean abundance), colony development, and varroa mite preference for drone and work bee brood cells were determined. The results showed that the application of drone brood cells as a control method was statistically significant against V. destructor, and did not negatively affect colony development. On the other hand, V.destructor's preference for both drone and worker bee brood cells among the groups was not statistically significant. In conclusion, drone brood cells ensured an approximately 43% success rate as traps against V. destructor compared to the control group. The effective application of drone brood cells as traps in combination with other Varroa mite control methods should be investigated.

Ethiopia has enormous potential for wheat production, yet it remains a net wheat importer. This paper aims to examine the efficiency of wheat production in Debra Libanos district, Ethiopia. Two stages sampling technique was used to randomly select 150 farmers for the study. A stochastic production frontier and two-limit Tobit estimator was utilized in the study. The study reveals that technical (78.5 %,), allocative (85.6%), and economic (66.7%) efficiencies. The yield gap was 5.13 quintal/ hectare showing a room to increase efficiencies. The study identified the determinants of wheat production efficiency in the area. Hence, to improve wheat production efficiencies strengthen extension services, improved technology utilization, and proper land ploughing. Besides, natural resource conservations that improve soil fertility should be the focus of the policymakers.

In this study, it was investigated the total amounts of phenolic and flavonoid substances and antioxidant activities in different solvent extracts of Lonicera iberica M. Bieb. wild fruit. Total phenolic contents of the extracts were determined as equivalent to gallic acid using Folin-Ciocalteu reagent, and total flavonoid contents as equivalent to quercetin by aluminium nitrate method. In addition, the antioxidant properties of the extracts were determined using free radical scavenging (DPPH) and reducing power (FRAP) methods. The amount of total phenolic substance of L. iberica fruits in hexane and methanol extracts was calculated as 30.96 ± 0.67 mg of GAE / g and 23.70 ± 1.56 mg of GAE / g, respectively. In addition, the amount of total flavonoid substance was calculated as 46.50 ± 8.54 mg of QE / g and 42.09 ± 2.58 mg of QE / g, respectively. It was determined that DPPH radical scavenging activity correlated with total phenolic and flavonoid amount of substance, and L. iberica had a strong antioxidant effect. It is predicted that our study will shed light on new researches, since it is the first study done with L. Iberica fruits in this field.

The aims of this study were to evaluate the total phenolic and pigment contents of five edible plants collected from Eastern Black Sea region and to test the storage stability of extra virgin olive oils aromatized with traditionally consumed plants. Aromatized extra virgin olive oils were prepared by addition of dry forms of local plants such as mendek (Aegopodium podagraria L.), çalıçilek (Vaccinium myrtillus L.), galdirik (Trachystemon orientalis L.), sakarca (Ornithogalum umbellatum L.) and hırnık (Diospyros lotus L.). Changes in the quality status of extra virgin olive oil were monitored with free fatty acid, peroxide value, total phenol content, pheophtyin a, lutein and beta carotene analyses during 5-month storage period at 24°C. Furthermore, hue and chrome values, total phenolic, chlorophyll and carotene contents were also analysed to determine the characteristic properties of plant samples. The addition of mendek and çalıçilek have remarkable effects on the transfer of phenolic compounds and pigments from plants to oil during all storage. It was determined that the addition of plant materials can improve the oil stability and cause to a lower free fatty acid and peroxide values in aromatized extra virgin olive oils. Obtained findings suggest that the aromatized olive oils with local plants is sensorial and nutritionally acceptable and can be used safely in aromatization and preparation of healthy and tasty foods at non-thermal process.

Mushrooms have been used as food and medicinal purposes for centuries. In this study, some edible Ascomycota were collected in 2018 and 2019 from Niğde, Turkey. Molecular identifications of the samples were performed afterward. PCR products were sent for sequence analysis after ITS fragments were amplified with suitable primers concerning DNA isolation of samples. The obtained data were compared with the Genbank database for samples’ determination. The mushroom samples were determined to be Terfezia claveryi Chatin and Morchella esculenta (L.) Pers. Samples were extracted by ethanol and methanol to determine antimicrobial activity using the disc diffusion method. Antimicrobial zones against microorganisms were measured. Then DPPH radical scavenging effects and total phenolic content of T. claveryi and M. esculenta mushroom samples were studied. The highest antimicrobial activity was observed in ethanol extracts of M. esculenta. When the DPPH radical scavenging activities are taken into account, the activity is increased depending on the concentration. The highest DPPH scavenging activity was found in the extract of M. esculenta with 40.86%. It was determined that the total phenolic substances in methanol extracts of mushroom samples varies between 533.28 ± 1,15-537.34 ±2.20 μg GAE / mg extract.

Probiotic yoghurt with fruit was produced to enrich the intestinal flora of infants and to prevent various ailments in infants when the flora is inadequate. Peach, apple and pear purees (10% and 20% each), cow milk, milk powder, starter culture (combination of Streptococcus thermophilus, Lactobacillus delbrueckii ssp. bulgaricus, Bifidobacterium infantis, Bifidobacterium bifidum, Bifidobacterium longum and Lactobacillus paracasei) were used in the production of probiotic yogurt for babies. Some properties of yoghurt samples were investigated during fermentation and on the 1st, 7th, 14th and 21st days of storage. After ten hours of fermentation, the lowest pH was observed in samples with apple puree. It has been determined that syneresis increases with increasing concentrations of fruit purees. The water holding capacity was less in yoghurts containing fruit puree compared to control yoghurt and in 20% fruit puree compared to yoghurts containing 10% fruit puree. The number of L. bulgaricus generally increased in all samples during storage. It was determined that the number of S. thermophilus in control sample was higher than other samples during storage. The number of L. paracasei and Bifidobacterium spp. decreased during storage. While the control sample remained probiotic until the 14th day of storage, other samples lost its probiotic properties before the 7th day of storage. Considering that the number of probiotic microorganisms in a probiotic product should be at least 106-107 CFU/g according to FAO, it has been decided that the most suitable fruits for probiotic yogurt with fruit puree are peach and apple, respectively. Considering the structural features, it is more appropriate to use 10% fruit puree, and considering the probiotic feature, it is more appropriate to use 20% fruit puree. Choosing the appropriate packaging and fixing suitable storage conditions will help probiotic microorganisms to preserve their vitality for a long time.
