This study aimed to investigate the effect of solid-state fermentation on the nutritional composition of Agaricus bisporus mushroom stalk and cap. Four homogenous test samples were prepared from the fermented mushroom stalk (Fermented MS), unfermented mushroom stalk (MS), fermented mushroom cap (Fermented MC), and unfermented mushroom cap (MC); each was independently analyzed in triplicates, providing a total of 12 independent measurements of all treatments. Nutritional changes in the mushrooms were determined by analyzing crude protein (CP), ether extract (EE), crude ash (CA), crude fiber (CF), hemicellulose, neutral detergent fiber (NDF), acid detergent lignin (ADL), and acid detergent fiber (ADF) contents. The best improvement in nutritional composition was obtained from the MS with increasing the crude protein (35 %). The results related to other parameters are similar among all the treatments, except for CF. To conclude, the fermented MS can be considered as an alternative protein resource in animal nutrition.

Bitkilerden elde edilen ekstrelerin birçoğunun biyolojik etkileri ve etki mekanizmaları hakkındaki bilimsel veriler hala yetersiz olmakla birlikte bu konuya olan ilgi her geçen gün artmaktadır. Bu çalışmada, Rumex crispus (Evelik) bitkisi mevsiminde Sivas yöresinden toplanarak kurutulmuş ve sonrasında yapraklı kısımlarından etanol, metanol ve su ekstraksiyonları elde edilmiştir. Çalışmanın amacı, elde edilen her bir ekstrenin bazı mikroorganizmalar üzerindeki antimikrobiyal aktivitelerinin değerlendirilmesi, toplam antioksidan seviyesi (TAS), toplam oksidan seviyesi (TOS), oksidatif stres indeksi (OSI) değerlerinin ve çeşitli hücre hatları üzerindeki anti-kanserojen niteliklerinin ortaya konulmasıdır. TAS, TOS ve OSI değerlerini tespit etmek için Rel Assay Diagnostics kitler kullanılmıştır. Bitki ekstrelerinin mikroorganizmalara karşı minimum inhibisyon konsantrasyonunu (MIC) belirlemek amacıyla mikrodilüsyon broth yöntemi kullanılmıştır. Çalışmada antimikrobiyal aktivite analizleri, Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212), Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922), Bacillus cereus (ATCC 11778), Klebsiella pneumonia (ATCC 13883), Candida albicans (ATCC 10231) ve Candida tropicalis (DSM 11953) mikroorganizmaları kullanılarak yapılmıştır.

Sonuç olarak, evelik bitkisinin etanol, metanol ve su ekstraklarının denendiği mikroorganizmalar üzerinde antimikrobiyal aktivitesinin bulunmadığı, yüksek düzeyde antioksidan aktiviteye sahip olduğu ve bazı hücre kültürlerinde sitotoksik aktivitesinin olduğu tespit edilmiştir.

Honey is the most known among the honeybee products. But apart from honey, there are other bee products that are nutritious and supportive of treatment. Pollen, royal jelly, and propolis are among the bee products that have the highest number of researches made in the last years. However, products such as bee bread (perga) and drone larvae (apilarnil) are very unknown products with little work. Apitherapy; bee and bee products as a method of complementary application in the protection and treatment of certain diseases. However, in order for these applications to be successful, the chemical and biological properties of these products need to be known. For this purpose, the definition, chemical and biological properties and therapeutic activities of bee products are included in this study.

Parsley leaves (Petroselinum crispum L.) weighing 100 ± 0.09 g were dehydrated from moisture content of 82.24 ± 0.07% to 10.01 ± 0.02 % (wet basis) using the microwave (MD), convective (CD), solar oven (SOD), sun (SD) and natural (ND) drying. Drying in MD, CD, SOD, SD, and ND was completed at 18±1.15, 61±0.58, 255±10, 330±5.29, and 1530±11.55 min, respectively. The energy consumption of MD and CD was measured as 0.213±0.009 and 0.427±0.015 kWh, respectively. In microwave drying, 700 W microwave output power was applied while convective drying was used with 50°C temperature and 1m/s air velocity. The sun and solar oven drying processes were carried out under the same conditions at the same time. The average temperature of the system during the solar oven drying was 81.7±1.5°C whereas the airflow in the system was 0.5 m/s. The data obtained from the experiments were also modeled using twelve different thin-layer drying equations, and thus the theoretical data were obtained. According to these theoretical data, the best model in the microwave and natural drying was Alibas’s equation while the most suitable model in the solar and convective drying was modified Henderson and Pabis’s model. On the other hand, it was seen that the best model in the solar oven drying was the Page equation. As a result, considering both quality and drying parameters, it was determined that MD and SOD were the most suitable method for drying of parsley leaves.

This research was conducted to determine the viticulture potential of Şırnak province. In the 6 districts including the provincial centre, an evaluation was made in terms of characteristics such as viticulture technique, cultivated varieties, pruning and cultivation forms, soil tillage, fertilization, disease and pest control and product usage methods. In addition, the climate and soil characteristics of the region were evaluated, and the viticulture profile of the province was revealed. As a result of the research, it was found that viticulture is essentially an important branch of agriculture in the province, especially in the province of Idil, but there is a decrease in the vineyard areas due to lack of care, terrorism etc. It is determined the tall of the existing vineyards are indigenous, as the climate structure is suitable for viticulture in general, high temperature and drought prevails in summer, excessive stoniness in some vineyards areas and water stress in most regions.

Phytogenic feed additives have replaced the use of antibiotic growth promoters (AGP) in the diet of poultry particularly broiler chickens. Researchers are moving towards the use of natural products such as herbs, spices, plants and plant products, which possess influential effects on growth performance parameters, immune response and treatment of various diseases. Aloe vera is a well-known medicinal plant and is being used for commercial and therapeutic purposes such as antimicrobials, antitumor, anti-inflammatory, immunomodulator, wound healing, antioxidant and antiprotozoal agents. From a few last decades, the use of Aloe vera has been increased as a natural additive to broiler diet. Based on the review of literature, Aloe vera can improve immune response, growth performance in the broiler, as well as an excellent alternative of AGPs and anticoccidial drugs. It can be used for broiler diet in the form of gel, powder, ethanolic extract and aqueous extract. This review provides information about the use of Aloe vera in broiler production with reference to the effects on growth performance, immune system, intestinal microflora and coccidiosis in broiler chickens.

This study was conducted to evaluate the muscles of the brisket region of the Eastern Anatolian Red (EAR) bulls in different ages subjected to different housing conditions and feeding style, and to determine the relationships among carcass traits, meat colour parameters and carcass measurements. Totally 25 bulls between 15 and 24 m of age were allocated to five groups (G1,G2,G3,G4,G5) according to feeding type, housing condition and age. The bulls were weighed fourteen days apart, feed consumption measurements were taken every morning, and slaughtered after 130 days of fattening. The differences were significant among G1-G3 for pelvic fat, total groups for conformation, among G1,G2-G3,G4,G5 for marbling, among G1,G2,G3-G4,G5 for LD area, among G1-G3,G5 for degree of fatten, among G1,G5-G2 for fat thickness over (LD) Longissimus Dorsi. The differences were significant in terms of meat colour parameters such as lightness (L*) in G1,G2,G3-G4,G5 and hue value (H*) in G1-G2,G3,G4,G5. Also, the differences among the groups are significant in terms of carcass length and width of the round. The correlation coefficients of carcass characteristic, colour score and conformation are negative with lightness (L*) and yellowness (b*). Degree fatten had a positive correlation with marbling score. Conformation were positively correlated with carcass length. Carcass ribeye area and L* showed a more desirable result in the G4 and G5 groups compared to other groups. Assessing the accumulated data of carcass traits with carcass components including carcass measurement during the slaughter or later phases of slaughter, it may be possible to use as a marker for the determining beef quality in EAR bulls.

This study was carried out to determine the concentrations of some heavy metals (Cd, Cu, Pb, Zn, Cr and Fe) in Solen marginatus (Pulteney, 1799) and sediments in the middle region of Izmir Bay. Metal concentrations in S. marginatus vary in the one-year period between summer 2005 and summer 2006. The order of accumulation of metal concentrates in soft tissue of razor clam was determined as Cd < Pb < Cr< Cu < Zn < Fe. Metal accumulations in the soft tissue of S. marginatus were compared with Provisional Tolerable Weakly Intakes (PTWI) and Provisional Tolerable Daily Intakes (PTDI) for human consumption. The results show that the maximum concentrations of metals were markedly below the limits of the FAO (Food and Agriculture Organization), WHO (World Health Organization) and TFC (Turkish Food Codex) for human consumption. The order of the metal concentrations detected in the sediment samples was Cd < Pb < Cu< Cr < Zn < Fe. In this study, the maximum heavy metal values determined in the sediment are below the criteria values of the stated for international sediment quality guidelines in the NOAA (The National Oceanic and Atmospheric Administration), OMEE (The Ministry of Environment and Energy of Ontario), ANZECC (The Australia and New Zealand Environmental on Conservation Council), CCME (The Canadian Council of Ministers of Environment). There was a statistically significant but weak correlation between concentrations of Cu and Cr in sediment and S. marginatus. The significant correlations have shown that Solen species can be used as a bioindicator species, such as mussels due to their ability to accumulate heavy metals.

This study was conducted in styrofoam trays placed on an aerated nutrient solution in vats in order to determine the effect of different nutrient solutions on rocket plant growth, yield and quality. Seeds of Bengi F1 rocket cultivar were sown into peat as inserting each seed to each hole (17 ccs) of trays with 210 cells (957 plant m-2). Following germination in the germination chamber, seedling trays were moved to a climate controlled greenhouse for adaptation. After emergence, the seedlings were transferred to water culture. The nutrient solution was applied as “full dose” (mg/L: N 150, P 50, K 150, Ca 150, Mg 50, Fe 5.0, Mn 0.50, Zn 0.05, B 0.50, Cu 0.03, Mo 0.02), “half dose” (macro elements reduced by 50%) and “without nutrients” (water). Cultivation was performed in 2 consecutive periods and in each period 3 harvests were done and quality analysis was done on the leaves from the first harvest. Results were given as the mean of two periods. Results showed that plant growth, yield and quality parameters vary depending on the concentration of the nutrient solution. It was observed that as the concentration of nutrient solution decreased, plant growth, biomass, yield values decreased, leaf color and total chlorophyll concentration did not change and while nitrate content decreased, vitamin C content increased. Leaf N, P, K and Fe element contents decreased with half dose, whereas Ca and Mg content did not change. However, there was no statistical difference between full dose and half dose treatments in many measured parameters. When all the data obtained from the study are evaluated together; it is suggested that rocket can be grown in a floating water culture and the dose of macro elements as reduced 50% can be preferred because it reduces the nitrate content, increases the vitamin C content and allows the use of less fertilizers without causing any significant reduction in yield compared with full dose.
