Tuğba Kök Taş | Erkut İlay | Ayla Öker
The aim of this study is to determine the quality characteristics of kefir by developing different flavours in order to increase its consumption. Plum (10%) and molasses (7.5%) which are rich in phenolic contents are used to produce kefir in different flavours. Chemical analysis (pH, titratable acidity, dry matter and colour), microbial analysis (total microorganism, Lactobacillus spp, Lactococcus spp. and yeast counts), total antioxidant activity (by ORAC method), total amount of phenolic contents and sensorial properties of all kefir samples were carried out at the 1st, 7th and 14th days of storage. Consequently, the results of pH, titratable acidity and dry matter in the kefir samples were determined to change between the values 4.11-4.39; 0.22-0.30 and 11.9-17.02% respectively, during the storage. In the colour analysis, the redness colour parameter of the kefir sample produced using molasses was determined to be higher compared to the other kefir samples. At the first day of storage, the total antioxidant contents of the control group kefir, plum- added kefir and molasses-added kefir samples were determined as 13.30; 16.80 and 17.35 µmol ml-1; and the total phenolic contents as 945.70; 2535.8 and 2357.6 mg ml-1, respectively. Content of total microorganism in kefir samples varied between 8.91-9.80 log kob ml-1during the storage period. Lactobacillus spp. and Lactococcus spp. contents of kefir produced using molasses were determined to have the highest values with 9.11 and 9.91 log kob ml-1, respectively, at the first day. Yeast content of the plum kefir and the molasses kefir samples including sugar was detected to be higher than that of the controlled kefir sample. According to the results of the sensory analysis, the kefir produced with plum was approved the most by the panelists. As a result of this study, two alternative products with quite high total phenolic content and antioxidant activity were developed for consumers.

This study was carried out to determine the influence of diets including different levels of protein and supplemented with probiotic-enzyme mixed on performance parameters and eggshell quality in laying quails. Japanese quails (n=120), 10 wk of age, were divided into 6 dietary treatment groups and the experiment lasted for 10 weeks. In each experiment group there were 5 replicates, and in each replicates there were 4 birds. Six diets, arranged a factorial design with three protein levels (16, 18 and 20 (control) %) and two levels of supplemented probiotic-enzyme mixed (0.0 and 1.0 g/kg) were used. Dietary crude protein levels and supplementation of probiotic-enzyme did not effect on the body weight gain, egg mass, feed intake, feed conversion, cracked egg yield, specific gravity and shell strength. However, egg production, eggshell thickness and eggshell weight were significantly increased by the addition of probiotic-enzymes mixed. Egg weight in group containing 18% crude protein was significantly higher than the containing 16% crude protein group. Results of the present study indicated that laying quails should be fed 18% crude protein and 1.0 g/kg of supplemental probiotic-enzyme mixed improved egg production and eggshell quality.

Microbial population of soil and its structure is affected with chemical and biological changes such as plant-root secretions. Upper layer of the soil is exposed to mixture of stems, fruiting bodies and leaves of trees. Seven trees growing at same area were chosen. Their upper layers of the soil were collected from depth 5-10 cm as samples in spring and autumn. Their microbial populations were investigated in order to determine in terms of climate changes. In order to determine the number of the total microorganisms, gram-negative bacteria and spore-forming bacteria (cfu/g) were used by the serial dilution techniques. As a result, the highest numbers of microorganisms from the soil of the apple tree were determined as the total microbial count in the autumn, although the lowest number of microorganisms was obtained from the soil of the pine tree. However, the number of the gram-negative bacteria was the highest in the soil of linden tree, although the number of gram negative bacteria was the lowest in the soil of apricot, mulberry and apple trees. For spore - forming bacterium, the highest number from the mulberry soil and the lowest number from the linden tree have been obtained. In the spring, the highest numbers of microorganisms from the soil of the apple tree were obtained as the total microbial count, although the lowest number of microorganisms was obtained from the soil of the apricot tree. For the number of the gram-negative bacteria was the highest in the soil of walnut tree, although the number of gram negative bacteria was the lowest in the soil of apricot trees. However spore - forming bacterium, the highest number from the soil of the poplar tree and the lowest number from the mulberry tree have been obtained. In general, the rich diversity of the microbial population was shown morphologically in autumn.
