Microorganisms have various stress response systems to maintain their viability when exposed to different stress conditions. In this study, Lactobacillus acidophilus ATCC 4356 and Bifidobacterium bifidum ATCC 11863 strains, used in probiotic yoghurt production, were subjected to acid (lactic and hydrochloric acid) stress to induce acid tolerance response (ATR). Yoghurts produced with both acid-adapted and non-adapted strains were stored at +4°C for 21 days. During the storage period, the pH and titratable acidity values of the yoghurts were measured, and the viability levels of the probiotic strains in the yoghurts were determined. In all yoghurt groups, a decrease in pH values and an increase in titratable acidity were observed during storage. The highest viability levels of the probiotic strains were detected on the first day of storage. Lactic acid-adapted Lb. acidophilus ATCC 4356 and B. bifidum ATCC 11863 in yoghurt showed growth at a level of 8.08 ± 0.12 and 8.08 ± 0.09 log10 Cfu/g at the first day of storage, respectively. Additionally, hydrochloric acid-adapted Lb. acidophilus ATCC 4356 and B. bifidum ATCC 11863 in yoghurt exhibited growth at levels of 7.90 ± 0.08 and 5.99 ± 0.03 log10 Cfu/g, respectively. The viability of acid-adapted Lb. acidophilus ATCC 4356 and B. bifidum ATCC 11863 showed a decrease similar way to that of the control group (non-acid adapted) during the storage period.

In recent years, there has been a growing interest in herbal remedies for therapeutic purposes. Aromatic plants have become a significant source of raw materials for the fragrance, food, and cosmetics industries. Additionally, the emergence of new applications and the trend towards natural nutrition and alternative healing methods, often referred to as "going natural," have increased the interest in medicinal and aromatic plants in our country, as well as in other countries around the world. In this study were investigated to determine yield and quality characteristics of seven different lavender (Lavandula intermedia Emeric ex Loisel. = L. hybrida L.) (Grasso, Süper-A, Seguret, Dutch, Abrial, Akmeşe, English) cultivars under dry and irrigated cultivation in Kahramanmaraş conditions between 2019 and 2020. The research was carried out in a randomized block design with 4 replications. Fresh stem flower yield was the highest variety Grasso(672.81kg/da). The lowest fresh stem flower yield was found in Seguret variety with 611.33kg/da The highest dry stemless flower yield was determined in Grasso variety with 59,66 kg/da. There were significant differences determined between cultivars the end of 2 years. The highest average fresh stem flower yield (693.067 kg/da) and the highest average dry branched flower yield (252.588 kg/ha) were measured in GRASSO variety.

This study was conducted to evaluate the quality features, antioxidant capabilities, microbiological and sensory aspects of yogurt fortified with 2%, 5%, and 7% red dragon (RD) peel powder. The yogurt was formulated using the classical technology adapted to laboratory conditions. The results of the physicochemical properties showed significant differences in pH (4.73–4.36), acidity (0.18–0.16 g lactic acid/100 g), and ascorbic acid (1.17-1.34 mg/100 g) among different yogurt formulations (P<0.05). In addition, RD peel powder fortification showed increasing trends in crude fiber (1.53-3.34 g/100 g), ash (5.19-5.29 g/100 g), and moisture (76.70-80.19 g/100 g) content, respectively; while the reversed trend was observed for fat (3.48-2.36 g/100 g), and crude protein (4.49-4.07 g/100 g) contents, respectively. Furthermore, gradual progression of RD peel powder in fortified yogurt manifested an improvement of the overall antioxidant activity (1.30-1.57 µmol TE/mL). The analyses of the sensory properties demonstrated that yogurt with RD peel powder in proportions of 2% received the highest hedonic score for consumer approval. Moreover, no coliform was reported in any of the control and fortified yogurts. Therefore, it could be concluded that RD peel powder can be employed as a functional food constituent in yogurt with improved quality attributes and sensory properties compared to plain yogurt.

Conducted within the National Sheep and Goat Breeding “subproject: Akkaraman Sheep Breeding Project under farmer conditions in Nigde’s Bor district” between 2018 and 2022, the current study evaluated the reproductive characteristics of ewes as well as the livability and growth traits of lambs. This study investigated some ‘reproductive traits’ of an average of 6000 ewes per year and ‘growth performance and ‘survival traits’ of a total of 30051 head lambs. The birth weight (LBW), 60th-day body weight (BW60), 120th-day body weight (BW120), and 120th-day body weight gain (BWG120) of Akkaraman lambs during the study periods were 4.14±0.19 kg, 18.58±0.03 kg, 31.31±0.02 kg, and 246±2.23 g/lamb/day, respectively. In the study, among the factors affecting the growth characteristics of Akkaraman lambs, only the effect of gender on BWG120 and birth type on BW120 was found to be insignificant. In contrast, the other factors were found to be found to be statistically significant. In the study, it was determined that the number of lambs per Akkaraman ewe giving birth between 2018-2022 varied between 1.03-1.10. The highest livability in Akkaraman lambs was determined in 2018 (96.61%) and the lowest in 2020 (83.21%). As a result, it was found that liveability in Akkaraman lambs was dependent on birth year, the age of the ewe, gender, and birth type.

Atakan Koç | Mehmet Öner
The aim of this study was to determine the fertility, herd life and milk yield characteristics of Simmental (SIM) cows of Austrian origin, which have increased the interest of cattle breeders in Türkiye in recent years. From the records of the farm between 2011 and 2021, the first calving age (FCA), calving interval (CI), herd life (HL), productive life (PL), lactation length (LL), lactation milk yield (LMY) and 305 days milk yield (305-dMY) were calculated. A total of 307 FCA, 619 CI, 212 HL and PL, 447 LL, 271 LMY and 497 305-dMY data were used. The means of FCA, CI, HL, PL, LL, LMY and 305-dMY for SIM cows were 842.35±5.30 days (28.1 months), 422.98±3.18 days, 75.48±1.72 months, 47.15±1.73 months, 363.52±3.52 days, 10,596±152 kg and 8647.0±58.0 kg, respectively. Based on the long FCA and CI averages of Austrian-origin SIM cattle, although it can be interpreted that there are some problems in terms of reproductive efficiency in the farm, finding long HL and PL and high milk yield, it can be said that the farm contributes to the increase of milk yield per cow by turning the negativity caused by the reproductive efficiency into an advantage.

Barış Kahveci | Muzaffer Yücel
Today, environmental issues are rapidly increasing due to the growing population, rapid and unplanned urbanization, industrialization pressure, and advancing technology. Consequently, there is an accelerated search for solutions to environmental problems. As in the formation of these problems, humans will be a key factor in solving them. Therefore, individuals need to be developed and equipped in terms of environmental awareness, environmental consciousness, and environmental sensitivity. Many studies in the literature advocate the necessity of education to increase environmental awareness; however, first and foremost, individuals’ environmental awareness must be identified and their levels must be revealed. In this study, noise pollution, which has been increasingly impactful in the last 30 years and is ranked as the second-highest burden of disease by the World Health Organization after air pollution, with less awareness compared to other environmental issues, is evaluated. In this context, the research area is selected as the Çukurova District of Adana Province, and the awareness of noise pollution among the residents in the region is assessed through survey forms and SPSS software. Additionally, using the survey results, the proportional values of noise pollution as the most significant environmental issue are evaluated as spatial analysis and mapped.

Plant fungal disease pathogens cause significant yield and quality losses in onion growing areas. In addition to yield losses, they cause negative effects that reduce the quality and export potential of the product, resulting in significant economic losses during harvest, post-harvest, processing and marketing stages. In recent years, Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) has emerged as a rapid, cost-effective, reproducible, and powerful technique for identifying microorganisms, and its impact on microbiological diagnosis has transformed workflow in equipped laboratories. In this study, proteomic analyzes were performed on Alternaria, Aspergillus, Fusarium and Penicillium species isolated from onion growing areas in Hatay, Amasya, and Tokat provinces. After extraction of mycelium from single spore cultures of the isolates with ethanol-formic acid, the spectra of the individual fungal isolates were determined using the Flex control software program. These spectra were compared with Maldi Biotyper Real-Time Classification (RTC) and identification was performed. Of 519 different fungal isolates, 435 representative fungal isolates (83.8%) were identified by MALDI TOF MS. Eighty-four fungal isolates could not be identified because they were not in a satisfactory range of purity and identification. Of the 435 isolates, 269 (61.8%) were identified as Fusarium spp., 80 isolates (18.4%) were identified as Alternaria spp., 60 isolates (13.8%) as Aspergillus spp., and 26 isolates (6.0%) as Penicillium spp. Among the fungal isolates, 72.5% of the Fusarium isolates, 78.8% of the Alternaria isolates, 90.0% of the Aspergillus isolates and 84.6% of the Penicillium isolates were identified as “highly probable” species with score values between 2.000-3.000 (green color). These species are Alternaria alternata, Alternaria infectoria, Aspergillus flavus, Aspergillus niger, Fusarium culmorum, Fusarium moniliforme, Fusarium oxysporum, Fusarium proliferatum, Fusarium solani, Fusarium verticillioides, Penicillium commune and Penicillium glabrum. The results clearly demonstrate that MALDI TOF MS biotyping may be used as a highly reliable and economical diagnostic method for routine diagnosis of diseases caused by Alternaria, Aspergillus, Fusarium and Penicillium species.

2023
Nazlı Şahin
The oleaster (Elaeagnus angustifolia L.), also known as wild olive, is a small fruit with three parts: the outer peel or exocarp layer, the edible part or mesocarp layer, and the inner seed or endocarp layer. The mesocarp layer is rich in essential vitamins and has great potential for use in various food products. The flour made from the mesocarp layer has a moisture content of 8.99%, an ash content of 2.66%, a fat content of 0.55%, a protein content of 5.99%, a crude fiber content of 3.32%, and a total dietary fiber (TDF) content of 26.36%. The TDF content is divided into insoluble dietary fiber (IDF) and soluble dietary fiber (SDF), which are 21.35% and 5.01%, respectively. The flour has color values of L*: 75.14, a*: 2.86, b*: 23.87, and a water activity value of 0.314. The water solubility, water absorption, and oil absorption are 67.33%, 4.91 g water/g sample, and 2.26 g oil/g sample, respectively. Additionally, the mesocarp layer contains minerals such as Mg, P, K, Ca, Fe, and Na. The mesocarp layer significantly affected the thermomechanical properties of wheat flour. As the substitution level of the mesocarp layer increased from 10 to 30%, the water absorption capacity, dough development time and stability time of the wheat dough significantly decreased. Specifically, the water absorption capacity dropped from 53.5% to 47%, dough development time reduced from 1.10 to 0.75 min, and stability time decreased from 8.90 to 2.25 min. Substituting a mesocarp layer in wheat flour can significantly improve product shelf-life due to slower retrogradation. The mesocarp layer is an functional ingredient in the food industry.

2023
Elife Büyüköztürk | Murat Oral
Renewing and reuniting the regions of cities that have become collapse areas with the city; urban renewal, which enables the city to be restored, is a term frequently used today. These collapsed areas need to be physically and socially renewed and revitalized. The main purpose of urban renewal studies is to reintegrate the isolated living spaces with the city. This integration should be realized not only physically and economically, but also socially and culturally. Kreuzberg Region in Germany suffered great damage in the World War II and turned into a depression zone over time. The “Protective City Renewal” method, which has been applied in the region since 1961, has an important place in urban renewal studies with its 12 basic principles. Urban renewal works in Tepebağ-Kayalıbağ neighborhoods, which constitute the historical city center in Adana province, are still at the very beginning of the process. Several projects have been carried out within the scope of street rehabilitation studies in the area, but these are thought to be insufficient. The aim of this study is to evaluate the “Protective City Renewal” method and to conduct an experiment on how the 12 principles of this method can be applied to the Tepebağ-Kayalıbağ section, which is an important historical texture to be preserved in Adana.

Black cumin has been used in many countries for the treatment of diseases such as cancer and diabetes, and for thousands of years as a spice, flavoring in products such as bread, and as a food preservative in pickles. Too much delay in the sowing of black cumin has a negative effect on plant growth. In order to determine the most suitable sowing dates for different black cumin genotypes, an experiment was conducted in the open-field conditions of the Eastern Mediterranean region of Türkiye at Çukurova University, for two years, in 2020 and 2021, in three different sowing dates (October 15th, November 01st, and November 15th) with three different black cumin genotypes (Çameli cultivar (G1), Adana population (G2) and Iraq population (G3)). The findings of this research demonstrated significant differences in the agronomic characteristics and overall quality of black cumin. The main components were p-cymene (51.45%-66.33%), trans-4-Methoxythujane (8.40%-11.90%), thymoquinone (0.11%-19.26%), γ-Terpinene (1.28%-9.09%), and limonene (2.93%-4.50%). The main fatty acids were determined as linoleic acid (53.97%-57.56%), oleic acid (20.98-26.40), and palmitic acid (13.73%-15.02%). Consequently, the low number of flowers and the high temperatures observed in May, along with the early spring frosts, negatively affected the fertilization of the flowers. The seed yield was adversely affected because some of the seeds could not mature.
