“…As the reaction progresses, the amount of methyl ester and glycerin also increases. Decreases in the yield may have been observed due to the purification problems that emerge during the separation of increasing glycerin from the product [13], [15].

In this study, the methyl ester production process from neutralized waste cooking oils is optimized by using alkali-catalyzed (KOH) single-phase reaction. The optimization process is performed depending on the parameters, such as catalyst concentration, methanol/oil ratio, reaction temperature and reaction time. The optimum methyl ester conversion efficiency was 90.1% at the optimum conditions of 0.7 wt% of potassium hydroxide, 25 wt% methanol/oil ratio, 90 min reaction time and 60°C reaction temperature. After the fuel characteristics of the methyl ester obtained under optimum conditions were determined, the effect on engine performance, CO and NOx emissions of methyl ester was investigated in a diesel engine with a single cylinder and direct injection. When compared to diesel fuel, engine power and torque decreased when using methyl ester, and specific fuel consumption increased. NOx emission increases at a rate of 18.4% on average through use of methyl ester.

“…Balık anestezisinde kullanılmak üzere karanfil yağı [13], nane yağı [14], kekik yağı [15] ve lavanta yağı [16] gibi bitkisel yağlardan elde edilen doğal ajanlar üzerine çalışmalar gerçekleştirildiği bilinmektedir. Sedatif ve anestezik etkileri yapılan çalışmalar ile ortaya konulan; alıç [17], limon otu [18], haşhaş [19], biberiye [20] bitki yağlarının balık materyalinde süre ve doz miktarının araştırıldığı bir çalışmaya rastlanmamıştır. Bu nedele sedatif ve anestezik bitki yağlarının konsantrasyonuna ve balıkların bu konsantrasyona hangi süreyle maruz kaldıklarına bağlı olarak kan indekslerindeki değişimler ile bunların fizyolojik önemleri bu çalışma ile ortaya konulmaya çalışılmıştır.…”

In this study, the oil obtained from hawthorn (Crataegus monogyna), lemon balm (Melissa officinalis), opium poppy (Papaver somniferum), rosemary (Rosmarinus officinalis) known to have sedative and anesthetic efficacy in traditional medicine were determined biochemical and hematological changes in blood of rainbow throut (Oncorhynchus mykiss) in 96 h and a concentration of 25 mg/L. There were statistically significant increases in the levels of ALT (alanin aminotransferaz), ALP (alkalen fosfataz), AST (aspartat aminotransferaz), LDH (laktat dehidrogenaz), glucose, cortisol, total protein, urea and creatinine levels in the groups treated with hawthorn, lemon balm and opium poppy when compared with the control group (P<0.05) and total cholesterol, triglyceride, sodium, potassium and iron levels were found significant reductions (P<0.05). In hematological parameters; there were significant increases (P<0.05) in erythrocyte, hemoglobin and hematocrit levels of fish treated with hawthorn and opium poppy oil and decrease in leukocyte count (P<0.05). Biochemical and hematological results have shown that hawthorn, opium poppy and lemon balm oil can also be used for sedation and anesthesia when compared to blood parameters obtained from studies with 25-50 mg/L concentration of clove oil commonly used as a natural agent in fish anesthesia. It is believed that hawthorn, opium poppy and lemon balm oil applied in concentration of 25 mg/L for 96 h may be used as an alternative antioxidant supplement in the regulation of the physiological functions of fish and may provide positive contributions to the health of the consuming organisms.
