2022
Veysel Doğan | Armağan Hayırlı
Mycotoxin is a worldwide problem threatening animal health and performance as well as public health. The objective of this experiment was to test the effect of ammonization on elimination of common mycotoxins in laying hen compound feed (CF) and dairy cattle total mixed ration (TMR). The CF for laying hens and TMR for dairy cows were contaminated with commonly occurring mycotoxins [aflatoxin B1 (AFB1), ochratoxin A (OTA), and zearalenone (ZEA)] at 25 times of their accepted legal limits (20 ppb, 200 ppb and 500 ppb, respectively). They were then subjected to ammonization with ammonium bicarbonate (NH4HCO3) at 50C for 24 hours under the atmospheric pressure. Mycotoxin levels were analyzed using the LC-MS/MS technique. The elimination levels in CF and TMR were 53% and 54% for AFB1; 31% and 31% for OTA and 22% and 22% for ZEA, respectively. In conclusion, ammonization was effective in destroying common mycotoxin, at an order of AFB1 > OTA > ZEA.

Fatih Mehmet Gür | İbrahim Aktaş
Kanser tedavisinde kullanılan ilaçların etkileri yalnızca kanser hücrelerine özgü olmayıp sağlıklı hücreleri de olumsuz etkilemektedir. Bu çalışmada antikanser bir ilaç olan paklitaksel’in (PAX) böbrek dokusundaki olası zararlı etkilerine karşı antioksidan etkileriyle öne çıkan silimarin’in (SLY) olası koruyucu etkilerinin ortaya konulması amaçlandı. Toplam 28 adet Sprague-Dawley cinsi dişi sıçandan rastgele bir seçimle: Kontrol, PAX, SLY ve PAX + SLY olmak üzere dört grup (n=7) oluşturuldu. PAX grubuna 2 mg/kg intraperitoneal yolla PAX, SLY grubuna oral gavaj sonda ile 100 mg/kg SLY, PAX + SLY grubuna ise önceki gruplarla aynı doz ve yolla PAX ve SLY uygulandı. Deneysel işlemlerin sonunda hayvanlardan alınan kan ve böbrek dokularında yapılan biyokimyasal analizlerde PAX’ın, böbrek dokusunda oksidatif stresi, serumda ise kreatinin (Cr) ve kan üre azotu (blood urea nitrogen, BUN) seviyelerini artırdığı tespit edildi. Böbrek dokusunda yapılan histopatolojik incelemelerde PAX’ın renal korpüskül atrofisi, fırçamsı kenarda hasar, vakuolar dejenerasyon ve deskuamasyon gibi patolojik değişikliklere yol açtığı gözlendi. Antienflamatuar, antiapoptotik ve antioksidan etkilere sahip bir farmakolojik ajan olan SLY uygulanması ise, PAX kullanımı sonucu meydana bu gelen patolojik değişiklikleri büyük oranda engelledi. Mevcut çalışmada elde edilen sonuçlar PAX ile yapılacak tedavilerde böbrek dokusunda şekillenecek zararlı etkilere karşı koruyucu olarak SLY’nin kullanılabileceğini gösterdi.

Yusuf Solmaz | Aydın Adiloğlu | Metin Turan
Wheat, which is one of the most widely cultivated crops in the world, has great importance in terms of economy. Wheat is one of the basic food sources of human beings, is one of the first cultivated plants. In order to meet the nutritional needs in parallel with the increasing human population, agricultural production needs to be increased. Fertilization is the most important factor in increasing the yield. Innovations in fertilizer technology and improvement of use efficiency are of great importance. In this study, different doses of mineral (0, 15, 20, 40 kg/da DAP and 0, 20, 30, 40 kg/da AS) and organomineral fertilizers (0, 15, 20, 40 kg/da 20: 20: 0 and 0, 20, 30, 40 kg/da 25: 0: 0) were applied with or without microbial encapsulation to wheat (Triticum aestivum L.) plants (Rumeli cv.) in pots. Some of macro and micro plant nutrients were analysed in three different harvest periods from seed sowing to compare the fertility of the applied fertilizers. According to the results of the research, all applications showed significant differences in terms of all examined parameters. Organomineral fertilizers were found to be more effective than mineral fertilizers. It has been observed that microbial encapsulation is effective at varying levels according to changing fertilizer type and dosage.

Dereje Haile | Bizuayehu Tesfaye | Fassil Assefa
Phosphorous is an essential macronutrient for plant growth and development. Most of the soil is deficient in plant available phosphorous and due to economic limitations majority of Ethiopian farmers applied inadequate fertilizers. It is essential to stabilize a mechanism to access P for plants with an efficient, cheap, and eco-friendly approach for enhanced crop growth and production. The main objective of this study was to screen efficient phosphate solubilizing bacteria from tomato rhizosphere soil. Using halo zone formation on PVK agar medium, more than 400 PSB isolates were isolated from 13 rhizosphere soil samples. By evaluating SI, texture in the culture-re-culturing process, liquid medium pH change efficiency and growth rate, upmost three promising PSB isolates (K-1-29, K-10-27, and K-10-41) were selected. Incubation of the isolates in PVK broth for five days showed significant pH reduction. For instance, isolate K-10-41 showed significant pH change (4.02) which indicates the organic acid production. Isolation and evaluation of efficient phosphate solubilizing bacteria maintain soil fertility, promote plant growth, induce plant response to pathogens, reduce agrochemical consumption and promote sustainable agriculture. Therefore, these selected PSB isolates need further detailed study for taxonomic identification, plant growth promotion, host range, and phytopathogen response. Local isolation improves environmental adaptation and indigenous competition.
