Article Citation - Scopus: 1Optimisation of the inhibitory effect of Lactiplantibacillus plantarum, nisin, and lysozyme to prevent the late blowing defect in a cheese model(Czech Academy Agricultural Sciences, 2024-10-30) Akbal, Sinan; Oner, ZubeydeThe present study employed response surface methodology (RSM) to optimise the prevention of late blowing defects in cheese during storage. The aim was to enhance the inhibition of Clostridium sporogenes in cheese by manipulating three independent variables: Lactiplantibacillus plantarum (utilising two different strains, labelled as A and B, the total cheese inoculation rate was 2% overall and the A : B ratio ranging from 25% to 75%), and lysozyme (ranging from 0 to 0.2 mg center dot L-1).The response variables considered in this model cheese study included the Clostridium count, pH, and titratable acidity. The results showed that the optimal conditions for inhibiting C. sporogenes and preventing late blowing defects in cheese were achieved with an L. plantarum A : B ratio of 49.54 : 50.46%, nisin at a concentration of 1.762 mg center dot L-1,and lysozyme at 0.2 mg center dot L-1.These results demonstrated not only effective inhibition of C. sporogenes, , a pivotal contributor to late blowing defects in cheese but also indicated favourable outcomes in terms of acidity parameters, which are crucial quality criteria for cheese production. The application of Response Surface Methodology revealed that late blowing defects can be prevented using relatively lower concentrations of antimicrobial agents, along with a judicious selection of appropriate cultures. This research highlights the potential for more efficient and costeffective strategies to maintain cheese quality by minimising the risk of late blowing defects.Article Citation - WoS: 3Citation - Scopus: 3New species of gall wasps (Hymenoptera: Cynipidae: Aulacideini and Phanacidini) inducing galls on plants of the genera Sonchus and Crepis (Asteraceae) in Romania (Dobrogea Province) and notes on their parasitoids(Magnolia Press, 2024-06-17) Schiopu, Ion; Tataroglu, Musa; Katilmis, YusufTwo new species of herb gall wasps (Hym., Cynipidae) developing on plants in the genera Sonchus L. and Crepis L.

The independent variables were drying temperature (50-70 degrees C) and microwave power (0-180 W), while the investigated responses were the drying time (D-t), the rehydration ratio (RR), the water-holding capacity (WHC), the antioxidant activity change (AA-PC), the total phenolic content change (TPC-PC), and the beta-carotene content change (BC-PC). The main criteria for the optimization of hybrid drying of sweet potatoes was to produce dried potatoes in the shortest drying time with a maximum RR and WHC and with minimum bioactive content (AA, TPC, and BC) loss. The optimum conditions were found to be a drying temperature of 54.36 degrees C with a microwave power of 101.97W. At this optimum point, the Dt, RR, WHC, AA-PC, TPC-PC, and BC-PC were 61.76 min, 3.29, 36.56, 31.03%, 30.50%, and 79.64%, respectively. The results of this study provide new information about the effect of the hybrid drying method (MW-HA) on the rehydration ability and bioactive compounds of sweet potatoes, as well as the optimum values of the process.Article The Physico-Chemical and Microbial Content of White Cheese Obtained Using Plant-based, Animal and Microbial Enzymes(2022-12-01) Arisoy, Zerrin; Ertürkmen, Pelin; Akbal, SinanIt is required to increase the amount of coagulant enzyme substitutes obtained from various sources that are equivalent to animal rennet in order to meet the rising demand for cheese. This study looked into the availability of plant-based enzymes as an alternative to rennet made from animals and microorganisms, which are frequently employed in the manufacturing of white cheese. Using animal (100% chymosin), microbial (obtained from Muchor miehei), and plant-based (Safflower seed, 80% chymosin-20 percent pepsin, purified from Cartamus tinctorius L.) enzymes, 6 varieties of raw and pasteurized milk cheese were made for this purpose. The values of SH, ripening index, water-soluble nitrogen (WSN), nitrogen dissolved in trichloroacetic acid (TCA), and yeast-mold increased after storage in cheeses made with various coagulant enzymes. During storage, the values for dry matter, pH, protein, Total Aerobic Mesophilic Bacteria (TAMB), lactobacilli, lactococci and coliforms all reduced. In terms of L*, a* and b* values, different rennet usage was discovered to be significant among cheese samples. The casein protein began to hydrolyze and the strength of the bands decreased in SDS-PAGE with the breakdown of the αs-casein and β-casein fractions on the 90th day of maturation in P1 and P4 numbered cheeses, which used plant-based enzyme made from raw and pasteurized milk. These changes in casein fractions resulted in a bitter taste in cheese made with plant-based enzymes. The use of plant-based enzymes in the manufacturing of white cheese was shown to produce results that were comparable to those of animal and microbial enzymes and did not have any negative effects on the cheese's physicochemical and microbiological quality parameters. When making fresh white cheese, the plant-based enzyme extracted from Carthamus tinctorius L. can be employed as a promising source of plant coagulants.Article SİYASETNAME’DE BÜROKRASİ(2023-04-04) Ergün, HüsnüBürokrasi, günümüzde bazen olumsuz sıfatlarla ilişkili olarak anılsa da işlerin düzenli bir şekilde yürütülmesine olanak veren bir yaklaşımdır. Siyasetname bu güne kadar birçok çalışmanın konusu olmuştur. Günümüzde de geçerliliğini koruyan öğütlere sahip bu eserin bürokrasinin öncüllerinden olabileceği düşünülmektedir. Bu çalışmada, çağında ve günümüzde hala isminden söz ettiren Nizamülmülk‟ün eseri Siyasetname‟de de bürokrasinin öncülleri araştırılacaktır. Hiç bir şeyin birden bire ortaya çıkmadığı, belli sebeplerle görüldüğü, belli aşamalardan geçerek ortaya çıktığı düşüncesinden hareket edildiğinde bürokrasinin de tarih içinde faklı şekillerde ortaya çıktığı söylenebilir. Bürokrasinin iş bölümü, uzmanlık ve liyakat, kurallar, hiyerarşik yapı, kişisel hak ve mülkiyet ile resmi hak ve mülkiyetin ayrılması özellikleri temel alınarak siyasetnamedeki öğütler incelenmiştir. Bu inceleme sonucu, bürokrasinin bahsedilen özelliklerinin Siyasetname içinde de varlığına rastlandığı anlaşılmaktadır.Article Citation - WoS: 1Citation - Scopus: 1DRIVERS OF EMPLOYEE DIS/SATISFACTION: A COMPARISON OF TOURISM AND SPORTS INDUSTRIES(Akdeniz Univ, Tourism Fac, 2023-06-01) Sevilmis, Ali; Kozak, Metin; Oezdemir, Ilknur; Ozdemir, IlknurThis study aims to identify the common and distinct factors affecting the dis/satisfaction of employees in two different industries, namely tourism and sports, and develop a model.

Moreover, these perceptions affect people's attitudes and behaviors on many issues. Especially, the increase of social media's influence has brought a new dimension to the interaction of individuals with brands, as well as influencing the factors that shape the relationship between them. This study attempts to observe how the perceptions of marketing activities carried out through social networks affect individuals' online opinion seeking and sharing behaviors. In addition, it is desired to discuss the effects of variables such as brand admiration, gender, online product purchase and online staying time that may have an impact on these perceptions. A quantitative research method was used. The questionnaire technique is a data acquisition techique of this method; this was used to obtain primary data. Difference tests (t-test, One Way Anova) and relationship test were performed in the analysis of the data obtained. The research conducted as part of the study confirmes that this perception is largely related to the behavior of seeking and transmitting opinions online. It was also found that the time spent online, the frequency of product purchases, brand admiration, and gender of users are related to this perception.
