Günümüzde bal arılarında dil çıkartma (PER) ve iğne çıkartma (SER) refleksleri gözlemlenerek koşullu şartlandırma araştırmaları yapılmaktadır. Araştırmalar sonucu narkotik maddeler, patlayıcılar, hastalıklar ve manyetik alanlar gibi olguların tespitinde bal arılarının biyo-sensör olarak şartlandırılarak kullanılabileceği gösterilmiştir. Bal arıları ile yapılan koşullu şartlandırma çalışmalarında doygun atmosfer spreyi ve dokunma yöntemleri dil çıkartma refleksi (PER) tespitinde yoğun olarak kullanılmaktadır. Bal arılarının farklı ırk ve ekotipleri ile yapılan bu çalışmada; doygun atmosfer spreyi ile şartlandırma yöntemi için, şartlandırma kabini içerisindeki işçi arılara aromatik bitki özütü içeren 50 cc atmosferik koku; yaklaşık 3 saniye içerisinde 5 cm mesafeden baş hizasına enjekte edilerek tanıtılmış ve arkasından 1/1 şeker-su (w/w) karışımı şurup ile ödüllendirilmişlerdir. Dokunma ile şartlandırma denemesinde ise yağlı aromatik bitki özütüne daldırılan ahşap kürdan işçi arıların antenlerine dokundurularak arkasından 1/1 şeker-su (w/w) karışımı şurup ile ödüllendirilmişlerdir. 15 dakika ara ile üç kez tekrar edilerek koşullu şartlandırılan bal arılarının şartlanma sonrası hatırlama oranları dil çıkartma refleksi (PER) davranışı gözlemlenerek şartlanma gösterip göstermedikleri tespit edilmiştir. Araştırmada kullanılan bal arısı ırk ve ekotiplerinin her iki yöntemle de şartlandıkları gözlemlenmiştir. Bal arılarının koşullu şartlanma uygulaması sonrası hatırlamada; dokunma uygulamasının doygun atmosfer spreyi uygulamasına göre daha fazla şartlanma ve hatırlanma oranına sahip olduğu tespit edilmiştir.

Kombucha is a beverage prepared from fermented traditionally-flavored black or green tea (Camellia sinensis L.) with symbiotic culture of bacteria and yeast (SCOBY). In this study, the changes in the physicochemical, bioactive components, microbial quality and sensory properties of black tea kombucha and different proportions of purple basil (Ocimum basilicum L.) kombucha after fermentation were evaluated. While the pH values decreased during storage, the total acidity value increased. Purple basil had higher total phenolic content at all storage times than the other samples. At the end of the study, it was concluded that the total amount of phenolic compounds and flavonoids in purple basil was highly conserved compared to the other samples. Antioxidant values on the 30th day determined highest DPPH (radical scavenging activity) (64.19%) and CUPCAC (cupric reducing antioxidant capacity) (41.48%) in the purple basil kombucha beverage. When the color values were examined, it was found that there were statistically significant differences in the overall storage process in all samples. There was no significant change inconsistency, smell, taste and general acceptance with the storage process. As a result, 30-day storage period was found to be more successful and favorable for 100% purple basil kombucha tea.

In this study, antioxidant activities of two macroalgae, Eucheuma sp. J.Agardh and Laminaria sp., J.V.Lamouroux used as food supplements were investigated. The antioxidant activity, free radical scavenging activity, the total content of phenolics, flavonoids and condensed tannins in extracts were determined. The IC50 values of the extracts of Eucheuma sp. and Laminaria sp. on DPPH scavenging activity was 2.26±0.03 mg/g and 2.63±0.03 mg/g of extract, respectively. The maximum total phenolic (5.31±0.04 mg GAE/g Ext.) were determined. According to our results, 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 48.45±0.06% (Eucheuma sp.) – 58.49±0.03% (Laminaria sp.). The highest flavonoid content was measured as 18.78±0.10 mg rutin/g of extract in Laminaria sp. The condensed tannins were not detected in Eucheuma sp. However, this value was measured as 6.24±0.60 mg CE/g of extract for Laminaria sp. According to our results, Eucheuma sp. and Laminaria sp., which are commercially sold in medicinal herb stores, are good sources of antioxidant components because of their phenolic and flavonoid contents.

In renewable system, to improve growth performance and enhance the stability of broiler meat may be alternative dietary garlic and its derivatives. The effects of dietary fresh garlic extract (FGE) or aged garlic extract (AGE) supplementation on performance, serum cholesterol and meat thiobarbituric acid (TBA) values and the organoleptic traits of cooked meats were investigated using 540 one-day-old Ross 308 broilers. Treatments: negative control (NC, basal diet), positive control (E200, basal diet + 200 mg vitamin E kg-1), FGE (FGE10, basal diet + 10 ml FGE kg-1) and graded levels of AGE (AGE5, AGE10 and AGE15, basal diet + 5, 10 and 15 ml AGE kg-1, respectively). Sensory appraisal was used to establish the consumer acceptability of boiled, grilled or roasted meats. FGE10 increased weight gain compared to NC, AGE5 and AGE10, whereas FGE10, E200 and AGE decreased serum cholesterol and meat TBA levels compared to NC. The alleviating effects of FGE10, AGE5 and AGE10 were higher than that of vitamin E. All garlic extracts did not affect the colour and nutritional quality of raw meat. Overall consumer acceptance of meat increased by FGE10, while it decreased by AGE10 and AGE15 compared to NC. Sensory scores of grilled meat were higher than for boiled and roasted meats. These results indicate that FGE proved an advantage for sustainable broiler production due to improve in the growth performance and consumer acceptance of cooked meat.

This study aims to fully controlled production of european catfish (Silurus glanis) and to increase fertilization and survival rates using different solutions and methods, enrichment of natural stocks with the obtained larvae and to provide participation as a new species in addition to species cultivated in Turkey. The study was carried out in Gürle Trout Farm in Manisa province. Eggs and sperm, that had been obtained from the broodstock, exposed to various fertilization methods and the fertilized eggs were put in the zuger jars and made triplicate trials. As a result, in this study, under the light of the findings obtained from different fish that was captured in different times and from two different regions; eggs that were treated with the urea-salt solution fertilization, eying and survival rates were higher than only salt solution application. Urea-salt solution for 10 minutes and the salt solution for 10 minutes were more successful. In addition, the time problem of working with living materials has become one of the biggest obstacles to this work. It is imperative that the reproductive cycle occurs once a year and in case of failure, it is needed to wait for the next cycle. In this context, it was not possible to tolerate the problems experienced in egg-taking, fertilization and survival activities in the last attempt. Therefore, the project had to be terminated here.
