Nezahat Turfan | Mertcan Karadeniz | Sabri Ünal
Ganoderma lucidum (Curtis) P. Karst (Reishi mushroom) is one of medicinal mushroom species. The chemical content of the mushrooms shows significant changes depending on the physical and chemical properties of their growing place. In this study; total soluble protein, total soluble carbohydrate (glucose, fructose and sucrose) and some mineral elements (P, K, Mg, Mn, S, Fe, Zn, Ca and Na) of Ganoderma lucidum collected from the nature and cultured on orange stump were investigated. According to the results; total protein, glucose, fructose, sucrose and starch content of the G. lucidum cultured on orange stump were found higher than G. lucidum collected from nature. Phosphorus, iron, sodium, potassium and sulfur content were determined to be higher in mushroom samples cultured on orange stump. Calcium, magnesium, manganese and zinc values were found as higher in mushroom samples collected from nature. According to these results, G. lucidum cultured on orange stump had higher nutritional value than mushrooms collected from nature.

2016
Hatice Kizilay | Handan Akçaöz
The purposes of this study were to determine the socio-economic characteristics of dairy farmers in Antalya, in Turkey, calculate the gross income, variable costs and gross margin of dairy farms, determine the probability distributions of consequences for alternative decisions to enable dairy farmers as decision makers to make a good and well-informed choice, to determine cross effects of milk prices variations on the productive strategy of dairy farms. The data were gathered via face to face interviews in Korkuteli, Dosemealtı, Elmalı, Manavgat and Serik counties of Antalya province in Turkey. The survey study was conducted with 80 farmers, who were member of Dairy Cow Breaders Union, in the 2011 production period. In this study, on the basis of previous experience, dairy farmers assigned minimum, maximum and most likely values of milk price and yield over the next period of 5 years. Then, triangular and cumulative distributions were defined by using these values. Moreover, Monte Carlo Stochastic Simulation model was developed to obtain distribution of expected gross margin per cow. The model and triangular and cumulative distributions were built in Excel with @Risk add-in software. The relationship of mean risk aversion coefficient, calculated by using negative exponential function, with both average gross margin and gross margin standard deviation values determined for each farm was examined. The results show that the relation between average gross margin and mean risk aversion coefficient was negative and significant at 5% level. But, although the relation between gross margin standard deviation and mean risk aversion coefficient was found to be negative, it was not significant at 5% level.

Leafy vegetables are highly perishable and often subjected to post-harvest wastes. Among the various methods of preservation, the effect of shadow drying on the nutritive value and antioxidant properties of five (5) leafy vegetables species widely consumed in Northern Côte d’Ivoire was investigated. These species were Amaranthus hybridus, Andasonia digitata, Ceiba patendra, Hibiscus sabdariffa and Vigna unguiculata. Experiment was conducted as follow: portions of washed and drained fresh leafy vegetables (500 g) were spread on clean filter paper and kept in a well-ventilated room of the laboratory at 25°C for 5, 10 and 15 days. The results of proximate composition after 15 days of shadow drying were: moisture (15.19 – 20.36%), ash (9.14 -19.54%), crude fiber (11.04 – 27.40%), proteins (11.14 - 17.94%), lipids (2.41 – 5.86%) and carbohydrates (16.59 – 45.14%). The concentration of minerals increased with respective values after 15 days of shadow drying: calcium (68.14-408.09 mg/100 g), magnesium (50.62-317.23 mg/100 g), iron (27.52-92.03 mg/100 g) and zinc (10.17-16.73 mg/100 g). During shadow drying, vitamin C and carotenoids were subjected to losses estimated to 35.52 – 70.50% and 22.82 – 45.63%, respectively. Contrary to these losses, antioxidant activity increased and ranged from 57.45 to 75.55 % after 15 days of shadow drying. All these results suggest that the considerable nutrient contents of shade dried leafy vegetables make them good source of food supplements in order to meet the nutritional requirements of Ivorian population.

Asuman Arslan Duru | Şerafettin Kaya
In this study, corn silage with different ratios of by adding olive pomace olive industry by-product under laboratory conditions was aimed to determine the effects on nutrient contents, fermentation characteristics and in vitro digestibility. Olive pomace used in the research, was added in 0% (control), 20 and 40 levels in corn silage and ensiling period continued during 56 days. At the end of the ensiling period, differences seen in terms of dry matter content, organic matter, crude fat, acit detergent fiber, acid detergent lignin, in each level consisting of corn silage is added to olive pomace were found significant but the crude protein content of the olive pomace-added silages decreased. The highest crude fiber value was determined in the silages added with 40% olive pomace. Crude ash, lactic acid, acetic acid, pH and CO2 differences seen in terms of rates were not found significant. Propoionic acid wasn’t found in the groups to which olive pomace was added, while butyric acid and ammonia nitrogen weren’t observed in all silage groups in the study. At the same time, in vitro organic matter, dry matter and neutral detergent fiber digestibility of silages increased in each level consisting of corn silage is added to olive pomace. As a result, it was considered result that olive pomace the oil industry by product can be a silo feed quality. In particular, the corns by adding 40% of the olive pomace made silage were obtained satisfactory results in terms of both physical and chemical properties.

In Côte d’Ivoire, the most fermented cassava food product is “attiéké”. Various microorganisms involved in this fermentation process. Bacillus spp. are well-known for their multi-potential enzymatic activities. In this study, Bacillus spp. strains were studied for their ability of growing in environmental stress as follow: NaCl (2 to 9%) and lactic acid (0.1 to 1%). The growth of the studied strains was inhibited at 5% (1 strain), 7% (2 strains) and 8% (7 strains) for NaCl and beyond 0.25% for lactic acid. The ability of the isolated Bacillus strains to ferment cassava dough for “attiéké” production was also tested. The results of sensory tests showed that “attiéké” produced with Bacillus spp. strains was quite similar to “attiéké” control (traditional “attiéké”) except for the brilliance and granulation for which the control obtained the highest scores. The present research indicated that cassava dough fermentation, initiated by the inoculation of Bacillus strains associated with or without lactic acid bacteria should be useful to improve and standardize the quality of “attiéké” produced in Côte d’Ivoire.

Gülsüm Yaldiz | Muhammad Sameeullah | Mahmut Çamlıca | Faheem Shehzad Baloch
Genetic variation is prerequisite for plant breeding. Nothing information existed in the literature for available diversity of Coriander accession in Turkey. Plant breeding activities are negligible in Turkey. So in order to start effective plant breeding program in Turkey, information on the available genetic diversity is viable. Therefore we planned to study the genetic variation and population structure of 29 Coriander accessions by seed storage protein (SDS). SDS analysis elaborated the lack of population structure and genetic bottleneck in the Coriander accessions in Turkey. Based on the results of this study, it was clear that sampling strategy was not appropriate and plant introduction should be made from different sources and diverse genotypes should be used as parents to initialize the effective Turkish Coriander breeding program.
