Anti-Quorum Sensing Effects of Some Medicinal and Aromatic Plant Extracts on Xanthomonas axonopodis pv. Phaseoli
2021
Tibebu Belete | Kubilay Kurtulus Bastas
Xanthomonas axonopodis pv. phaseoli (Xap) is known as one of the most important seed-borne destructive pathogens on beans worldwide. Nowadays, Xap is considered to acquire resistance to antibiotics and synthetic bactericides which concerns the scientific world for its future management. This has made the use of plant extracts, the best alternative in the control of plant disease pathogens by inhibiting the quorum sensing (QS) mediated virulence factors. This research was designed to investigate the antibacterial activities and the anti-QS effects of the 14 different aromatic and medicinal plants against QS-mediated virulence factors of Xap. The results revealed that Syzgium aromaticum showed the largest inhibition zone diameter and strongest antimicrobial (antibacterial) effect among the 14 plant extracts followed by Thymus vulgaris and Coriandrum sativum. Similarly, the lowest swarming, swimming, and twitching motility values were measured from the Syzgium aromaticum application followed by Coriandrum sativum, Thymus vulgaris, Brassica nigra, Lepidium sativum, and Ruta chalepenis. These results indicated that S. aromaticum, C. sativum, T. vulgaris, B. nigra, L. sativum, and R. chalepenis will be a potential candidates as anti-quorum sensing agents in preventing common bacterial disease of beans caused by Xap. Compounds derived from aromatic and medicinal plants have demonstrated successful control of diseases in crops and the use of these substances provides a valuable tool to the growers around the world for diseases management in organic production.

Sinan Dündar | Hüdaverdi Bircan | Hasan Eleroğlu
The compost product, which is a biologically active substance, emerges as a result of microbial decomposition of organic materials under controlled conditions. This product, which is used for the improvement of soil structure and the development of agricultural products, also offers opportunities in terms of minimizing the damage caused by organic wastes to the environment. It is important to encourage efforts for compost production, especially in terms of both disposal and economic evaluation of wastes generated in animal production farms. Determining the most suitable location of a facility for the utilization of animal wastes as compost, which will be obtained from livestock enterprises scattered in different geographical areas, will be an essential study in terms of minimizing operating costs. For such a facility, it would be an appropriate approach to use multi-criteria decision making methods to choose among predetermined facility location alternatives. In this study, a total of 17 facility location alternatives with 83,163 cattle potential in Çorum province were ranked according to the criteria determined and weighted by means of SWARA method. The optimal ranking of 17 alternatives determined by K-Means clustering analysis was carried out by COPRAS and MAIRCA methods. According to the ranking results obtained from both methods, it was determined that cluster number 6 was in the first rank, cluster number 4 was in the second rank, and cluster number 3 was in the third rank.

Güzella Yılmaz | Hakan Karadağ
In the study, it was aimed to increase the vase life of Basic, Ulaş and Terra Ozan cultivars of Gerbera sp. For this purpose, microcapsules containing lavender oil (1000 and 1500 ppm) and naturally obtained walnut tea (33% and 50%) were used. Sucrose (4%) was added to all vase solutions, including the control group solutions. The experiment was set up with 3 replications (three vases) for each treatment and one flower per replication. As a result of the experiment, it was observed that both walnut tea and lavender treatments did not cause a significant change in the vase life of the Terra Ozan cultivars. In the Basic cultivar, the vase life of the flowers in the solution containing lavender oil was longer than that in the solution containing walnut tea, but both treatments did not make a significant difference compared to the control. In Ulaş, both walnut tea and lavender oil applications caused significant increases in the vase life of the flowers. The applications made in the study caused significant changes in the water intake of the flower stems. The treatments that increase the water intake also increased the vase life.

Kerim Demirgül | Ergin Ozturk
Tomato pomace (TP), utilized improperly is not namely causes a waste of valuable resources but also increases environmental pollution. In this study, possibilities improving nutrient composition by fermenting dry TP with Aspergillus niger was investigated for the value-added utilization of this pomace in animal feed. The TP, dried at 65°C for 8 hours with a simple layer and under a laminar airflow drying oven, was subjected to solid-state fermentation. After unfermented and fermented dry pomaces were milled in 2 mm sieve, proximate analysis and the analysis of cellulosic fractions were performed. Roughage quality indices were calculated using cellulosic fractions. Fermentation of TP with Aspergillus niger inoculant increased the amount of dry matter (82.98 vs 91.47%), crude fiber (21.71 vs 23.00%), neutral detergent fiber (29.70 vs 35.92%), acid detergent fiber (25.22 vs 26.84%), acid detergent lignin (7.91 vs 10.77%), hemicellulose (44.71 vs 90.78), crude protein (13.70 vs 21.37%), ether extract (2.82 vs 3.52%) and ash (10.57 vs 13.24%) compare to unfermented TP. Fermentation process decreased nitrogen-free extract (51.19 vs 38.86%), non-fiber carbohydrates (46.03 vs 29.47%) and quality index as relative feed value (216.9 vs 176.1) and relative forage quality (242.5 vs 195.5) and metabolizable energy (2.66 vs 2.60). Ferric reducing antioxidant power (FRAP), DPPH free radical (2,2-diphenyl-1-picrilhydrazil) and total phenolic content of TP did not increase by fermentation. Concentration of β-carotene and lycopene of TP decreased after fermentation with A niger. The results indicate that the selected strains of A. niger can be used to enrich the chemical composition of TP, except for cellulosic fractions and also carotenoids and antioxidant activity.

Turkey is among the rare countries in terms of plant diversity, and thus, most plant species spread widely throughout the country. Apricot is one of these plant species. Due to the self-incompatibility seen in apricots, it is necessary to use a pollinator variety for a quality and efficient product. With this study carried out in 2021 year, the effects of different pollinators on fruit set and some fruit quality parameters of Casne Drenova, Ninfa and P. de Tyrinthe cultivars were investigated in Kayseri ecological conditions. In the study, early ripening apricot varieties were used as paternal parent. According to the results of the study, it was shown that fruit set values varied between 11.6% and 22.6%. In the pomological parameters examined in the study, in general (except for fruit firmness), differences were found in combinations using different pollinators compared to the open pollinated fruits of the maternal parent. It is foreseen that the results obtained will be guiding especially in the breeding studies to be carried out with these varieties and in the establishment of new orchards.

2021
Sema Yaman Fırıncıoğlu | Hatice Nur Kılıç
Despite positive effects on nutrition, it has been reported that milk causes allergic reactions and many health problems. Allergic reaction to milk is called lactose intolerance, but it is estimated that this is not caused by lactose, but by the β -casein structure of milk, which varies depending on animal species. Although there are many fractions of β-casein in the structure of milk, especially A1 and A2 casein attract attention. A1 β -casein causes many health problems because it plays a role in the formation of the bioactive opioid peptide β-casomorphin-7 (β-CM-7). These health problems are allergic reactions, weakening of the immune system and slowing down of the gastro-intestinal system and some systemic diseases (cardiovascular disease, type 1 diabetes, autism, schizophrenia). The underdevelopment of gastro-intestinal system, especially in newborns, causes us to encounter these health problems more frequently. For this reason, the consumption of milk containing A1 β-casein, especially cow’s milk from culture breeds, is not recommended. Since BKM-7 (β-casomorphin-7) formed by A1 β-casein cannot occur in A2 β-casein, these health problems cannot be expected to be observed. However, A2 β-casein causes DPP4 (dipeptidyl peptidase 4) enzymes to be regulated in the body and a non-opioid effect is observed. It is recommended to consume goat’s milk and dairy products containing A2 β-casein in newborns, people with celiac disease and stomach disorders. Despite the lack of studies on the subject of A1 and A2 β-casein and the ongoing discussions, in this review, the importance and differences of A1 and A2 β-caseins in cow and goat milk were discussed and their effects on human health.

The present research was carried out to determine the effects of the addition of cardamom powder at different levels (0, 1, 2, 3 or 4 g/kg) to diet on performance, egg quality, and serum parameters in laying quails. In the experiment, a total of 120 laying quails at the age of 20 weeks were randomly distributed to 5 treatment groups with 6 subgroups (4 quails each). Quails were fed with experimental diets for 10 weeks. In the experiment, the feed intake of quails significantly increased with the supplementation of cardamom powder at the level of 3 g/kg to the diet, while other performance parameters were not affected. Eggshell thickness advanced with the addition of 1 g/kg cardamom powder to diet. Egg yolk L* value increased at the level of 4 g/kg, but a* value decreased with the addition of cardamom powder. Other egg quality parameters were not affected by the addition of cardamom powder to the diet. In addition, the supplementation of cardamom powder to the diet significantly reduced serum cholesterol levels of quails. According to the results obtained from the experiment, the addition of cardamom powder at the level of 3 g/kg to the diet increased the feed intake of quails, while the supplementation of 1 g/kg was effective in improving the eggshell quality and serum cholesterol level.
