The main aims of this study were to observe the seasonal variations of physicochemical parameters and heavy metal content, to determine the water quality properties and the suitability level in terms of aquatic life, and also to classify the quality of water in accordance with the Surface Water Quality Management Regulation (SWQMR) criteria at Çiğdem Pond (Kastamonu/Turkey). In total, 21 physicochemical parameters and 7 heavy metals were investigated for water quality assessment of the studied pond between July 2015 and June 2016 in 3 stations. The water quality in Çiğdem Pond was found to be Class I according to SWQMR. The results of this study provide a data baseline for future studies on subsequent evaluations of possible future environmental contamination. Also, to protect the water quality and to ensure the health of aquatic life in this area, it is required to make regular observations.

The purpose of this study was to determine the antibacterial activity of plant derived compounds and essential oils of Corymbia citriodora against selected Gram negative and Gram positive foodborne pathogens in broth dilution assay. The combination of compounds (cineole, terpinen-4-ol and α-terpineol; CTαT) were further tested at three different concentrations (0.2, 0.4 and 0.8%) for the killing effect against E. coli O157:H7 and L. monocytogenes in milk including whole fat and skim fat. CTαT showed antimicrobial activity against all bacteria tested at minimum inhibition concentrations (MICs) from 0.125% to 1% in broth dilution assay. Linalool was also found to be antimicrobial at MICs between 0.25% and 2%, but not for Enterococcus casseliflavus. Further study carried out in milk showed that CTαT at concentrations of 0.4% and 0.8% significantly reduced the population of E. coli O157:H7 under detection limit in skim milk, whereas it was only effective at 0.8% in whole fat milk. CTαT, on the other hand, shown to be less active towards L. monocytogenes as only significant effect was observed at 0.8% in skim milk. Taken together results of the present study indicate that plant derived compounds could be valuable alternatives to inactivate foodborne pathogens in milk.

Pawpaw (Carica papaya Linn) seeds, peels and leaves are well known for their medicinal and potent pharmacological values. The plant belongs to the family Caricaceae and its fruit is commonly known for its food and nutritional values. Though the roots, bark, peel, pulp and the seeds had been shown to have medicinal properties, little is known about their nutritional properties. During the last few years, there had been series of research to explore further pharmacological and medicinal properties as well as it nutritional qualities of these plants parts, thus giving rise to it nutraceutical abilities. Scientific attempts have also been made over the decades to authenticate its nutraceutical properties. While nutritional constituents such as oil, proteins, and minerals haven been characterised from its seeds, little is known about other parts of the plant. Though the nutraceutical properties of papaya as drug or quasi-food product are not well understood or value, still it is an important gift of nature that is readily available in our eco-world and worth exploring. This review focuses on previous studies by various researchers on the medicinal, nutraceutical properties as well as the antioxidant potential of these plant parts and suggestions for further studies as regarding the optimisation of the potential of this plant.

In this study, genetic parameters, macro environmental factors and genetic, phenotypic and environmental trends for actual and 305 day milk yield of Brown Swiss cattle reared in Research Farm of Agricultural College at Atatürk University were estimated. Estimated breeding values that were used for calculation of the genetic trend and genetic parameters were estimated by using MTDFREML computer package program. Environmental factors affecting on actual and 305day milk yields were analysed by using Harvey statistic package program. While effects of the years and parities on the actual and 305-day milk yields were highly significant, the influence of the calving season was found to be insignificant. Environmental and phenotypic trends for actual and 305-day milk yields were determined as -33.2 kg and -29.0 kg; and -27.8±19.1 kg/year and -25.9±8.7 kg/year respectively. Genetic trends for actual and 305-day milk yields were calculated as 5.4±3.8 kg and 3.1±3.4 kg. Heritability’s for actual and 305-day milk yields were 0.21±0.12 and 0.16±0.14 respectively. Repeatability values for actual and 305-day milk yield were found as 0.29 and 0.33 respectively.

The economic evaluation for the production of fruit juice from the Africa star apple otherwise known as ‘Agbalumo’ in the south western part of Nigeria was evaluated using the NPV (Net Present value) and IRR (Internal Rate of Return) methods assuming a uniform cash flow over a 10-year plant life. Sensitivity analysis was conducted by varying the number of production days (330, 300 and 250 days) at 100% plant capacity and varying the plant capacity (100, 85 and 70%) for a 330-day production schedule. Some components of the operating cost reduced with number of days and plant capacities. The production cost and product cost per unit increased with either plant capacity utilization or the number of days. It was observed that product cost/ 500ml Tetra Pak of Agbalumo juice at 85% and 70% stood at ₦37.48 while payback time/profitability percent had better index at 300 and 250 days compared to 330 days of plant operation. The results further indicated that the plant should not be operated for less than 250 days and plant capacity utilization of 70% in the year. Flexibility in the plant capacity utilization in the range of 70%-85% for 330 days shows a good economic performance as well as result of the NPV and IRR for this operating condition.

Five strains of Lactococcus, including L. garviae K2, L. piscium SU4, L. lactis subsp. cremoris E22, L. plantarum L7 and L. lactis subsp. hordinae E91 were screened for production of antimicrobial agents. The strains were also analysed for antimicrobial activities against spoilage and pathogenic organisms, including Staphylococcus aureus, Salmonella Typhimurium, Escherichia coli, Yersinia enterocolitica, Pseudomonas aeruginosa, Klebsiella pneumoniae, Listeria monocytogenes, Bacillus cereus and Pseudomonas fluorescens.

In this study, the cattle and small cattle presence in Turkey and in the area of TR83 which consists of Amasya, Çorum, Samsun and Tokat provinces were analysed. Trend analysis were carried out using the data obtained from cattle and small cattle presence with the help of the values of the period of 1996 – 2014 and estimated values for 2020 were specified. It is seen in the projections for the 2020 that, domestic cattle breeds are expected to be decreased in number whereas it is expected to be increased in the TR83 area. Also it is estimated that the number of the whole animal existence which are investigated by the study will increase by the year 2020. It is beyond question that the positive effects of the present policies supporting stockbreeding on this increase is apparent. In this sense, the determination of the contribution of present stockbreeding support policies to the sector and their effectiveness and the investigation of their faulting aspects are important in order to develop more accurate and effective policies.

Increasing of industrialization and population has resulted in the accumulation of a wide variety of chemicals. Especially, widespread use of synthetic and toxic chemicals have led to an effort to improve new technologies to reduce or eliminate these contaminants from the environment. Chemical methods that used for the treatment of toxic materials are expensive, time-consuming and difficult, especially in extensive agricultural areas. Furthermore these methods led to formation of new chemical pollutants. Recent years, one promising alternative treatment method is to use of microorganisms for the biodegradation of these toxic chemicals. This method is effective, minimally hazardous, economical, versatile and environment friendly. In this study, we thought that microflora of insecticide resistant insects may be a potential reservoir for the isolation of new bacteria that can be used for the biodegradation of insecticides. In this research work, totally 24 bacterial isolates capable of biodegradation α-endosulsan were isolated from the body microflora of insects belong to Orthoptera, Dermaptera, Mantodea and Hymenoptera orders. Based on the some morphological, physiological and biochemical characteristics and fatty acid profiles they were identified as Stenotrophomonas, Pseudomonas, Acinetobacter, Bacillus, Brevibacillus, Flavimonas and Rhodococcus. As a result, these isolates can be used for the treatment of α-endosulfan residues at different environments.
