Oils constitute a major source of plant-based protein. A major limitation to optimal oil consumption in sub-tropical region is fungal infestation and consequent mycotoxin contamination. Ten refined and eight unrefined vegetable oils were randomly purchase from open markets and screened for microbial contamination using standard microbial procedures. Twenty six fungi isolates were obtained from the vegetable oil samples, the isolates were identified as Aspergillus fumigatus (43.0%), Mucor (17.9%), Saccharomyces cerevisiae (10.7%), Aspergillus niger (7.1%), Aspergillus flavus (7.1%), Penicillium spp (7.1%), Aspergillus oryzae (3.6%), Mucor (17.9%) and Rhizopus spp (3.6%). Five out of the ten refined vegetable oil samples had no fungal contamination. A. flavus and A. oryzae were absent in all the refined oil samples while A. niger was absent in all the unrefined oil samples. Isolation of mycotoxigenic fungi such as Aspergillus spp. is of vital importance in the food industry. Education and training of processors and consumers is recommended.

The present study was conducted in the province of Duhok (Northern Iraq) between 2011-2012. The study attempted to determine the use of certain indigenous and cultivated plants in Duhok province in alternative medicine and place of these plants in systematics. Thus, 49 taxa in 27 genera and 46 species were identified. Two taxa belonged to Coniferophyta, one belonged to Pteridophyta and 46 belonged to Magnoliophyta dividions. It was determined that the family with the most numerous taxa in the region was Rosaceae with 5 taxa, followed by the Fabaceae and Lamiaceae family with 4 taxa and Apiaceae, Asteraceae, Cucurbitaceae and Poaceae family with 3 taxa each. Certain ethnobotanical features of the identified taxa, such as systematics, habitats, flowering times, local names and alternative uses in medicine were presented.

The aim of this study was to determine the effect of deficit irrigation on yield for cabbage grown under unheated greenhouse condition. The research was carried out at the Agricultural Research Station of Yenişehir High School of Uludağ University in Bursa, Turkey, in 2008. In the study, water was applied to cabbage as 1.00, 0.75, 0.50, 0.25 and 0.00% (as control) of evaporation from a Class A Pan corresponding to 2 day irrigation frequency. Irrigation water applied ranged from 70 to 520 mm and water consumption ranged from 90 to 548 mm. The effect of irrigation water level on the yield, head height, head diameter, head weight and dry matter were found to be significant. The highest yield was 72.8 t ha-1. Crop yield response factor for cabbage (ky) was found as 1.036. The highest values of water use efficiency (WUE) and irrigation water use efficiency (IWUE) for 2008 year of K2cp treatment was calculated to be 0.143 kg m-3 and 0.137 kg m-3, respectively. K2cp application (75%) can be recommended as the most effective irrigation level for the cabbage to which drip irrigation is applied under scarce and unheated greenhouse conditions.

Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity. However, many plant genetic resources, including geophytes, are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Lilium ciliatum is endemic to North East Anatolia. IUCN (International Union for the Conservation of Natural Resources) Red List Category of this species is Endangered (EN). Lilium ciliatum naturally grown in Zigana pass, Bayburt, Trabzon, Bulancak, Giresun and Gümüşhane is endangered and major threats of L. ciliatum are road construction and human disturbance related to ecotourism and recreation. It was reported that Lilium carniolicum naturally grown in Turkey is endangered although it isn’t in the IUCN Red List. Distribution areas of L. carniolicum are Trabzon, Rize, Artvin and it is also endemic to North East Anatolia. These species have high potential for use as ornamental plants with their colorful big flowers. In addition, the bulbs of these species are also used in the cosmetic industry and medicine. These are the main properties that increase the importance of L. ciliatum and L. carniolicum species. Therefore it is very important to protect the habitats of these species, ensure the continuity of their generations. The disappearance of these endemic species from our country means to disappear from the world. This review has been given in order to give some information about the endangered Lilium species of Turkey and conservation actions on these species in Turkey flora and take attention to the issue.

The most common honey bee diseases are American foulbrood (AFB) caused by the bacterium Paenibacillus larvae, Chalkbrood caused by fungus Ascosphaera apis and diseases caused by parasitic mites such as Acarapis woodi, Varroa destructor. These diseases and pests not only cause economic loss but also cause ecological problems related to the role of honey bees, as the most important pollinators on Earth. Synthetic acaricides and antibiotics are used to keep the diseases and mites in control. Use of the drugs lead to the development of drug-resistant organisms, detrimental effect on non-target organisms and the residue problem in bee products. For this reasons, the need for alternative control methods has become compulsory in recent years. It has been known that some plant oils used widely in perfumery and food industry for flavor and smell have been used as repellent to certain insects, bactericide and fungicide. Therefore, intensive studies have been carried out on plants with anti-mites, antibacterial and antifungal potentials and these studies are still going on. Recently, studies in this area have shown that essential oils of plants such as thyme, cloves, mint, lemon grass, cinnamon, grapefruit, rosemary, marigold, are lethal to some mites, bacteria and fungi. In addition, it has been reported that some components, isolated from these plants such as sanguinarine, thymoquinone, capsaicin, carvacrol, citral, eugenol, thymol, show these effects on the organisms. As a result, in countries rich in biodiversity due to endemic plant species, the essential oils used in control of these diseases should be favored instead of or in combination with conventional drugs in integrated the disease management programs because of the lack of harmful effects of essential oils on non-target organisms and environment.

In this study, effects of propolis on immunological parameters of rainbow trout were investigated. For this purpose, propolis was intraperitoneally injected to fish 4 times at doses of 2.5, 5 and 10 mg / kg fish weight. Blood samples on 3, 9, 15 and 21 days were collected from fish of the control and experimental groups and analysed to determine oxidative radical production [nitroblue tetrazolium (NBT) activity], total plasma protein and total immunoglobulin levels. At the end of the experiment, there was a statistically significant increase in oxidative radical production, total protein and immunoglobulin levels of propolis treated groups when compared to the control group.

This study investigated the prevalence and concentration of antibiotic residues in twenty brands of milk. Determination and quantification of antibiotic residues was done using High Performance Liquid Chromatography. Aerobic plate count was carried out and the associated bacteria isolated. Identification of bacteria was done using standard microbiological methods. Molecular characterization and identification of bacterial isolates was done using 16S rRNA gene sequencing method. Antibiotic sensitivity was carried out on bacterial isolates using disc diffusion method. Plasmid profile of drug resistant isolates was done using alkaline analysis method. Comparison of means was done using Analysis of Variance. Antibiotic residues were detected in 10 (50%) of the 20 milk brands analyzed. The residual levels of tetracycline, oxytetracycline and chlortetracycline ranged between 5ng/kg and 1569ng/kg while none of the samples had doxycycline residues. The prevalence of tetracycline residues in evaporated milk brands and powdered milk samples were 100 and 23 % respectively. The aerobic plate counts ranged from 2.5 × 102 to 6.5 × 102 CFU∕mL for evaporated milk and 2.5 × 101 to 6.0 × 101 CFU∕mL for powdered milk. A total of ten bacterial species were isolated and identified. Susceptibility result showed that 95% of the isolates were sensitive to erythromycin, cefuroxime and gentamycin; 12.5% were resistant to tetracycline and ampicillin, 10% were resistant to ofloxacin and 7.5% to doxycycline and penicillin. Five of the bacterial isolates were resistant to more than one class of antibiotics. Resistant isolates subjected to plasmid profiling had detectable plasmids with estimated sizes between 120bp and 1000bp. The obtained results provide evidence that the presence of antibiotic residues in evaporated and powdered milk is an indication that the public is exposed to the harmful effects of the residues.

Food insecurity in Sub - Saharan Africa (SSA) is on the rise due to soil fertility depletion and in Kenya, Nitrogen (N) is one of the widely deficient nutrients. Biological nitrogen fixation (BNF) can replenish N into the soil system. A study was carried out in acid soils at Koyonzo and Ligala sites of western Kenya to determine the effectiveness of different inoculants after agricultural lime application in enhancing BNF and yields of groundnuts (Arachis hypogea L.) and maize (Zea mays L.) intercrop. Red Valencia groundnut variety was intercropped with Hybrid 513D maize variety. A6w, W1w and V2w indigenous rhizobia strains were tested alongside a commercial rhizobia strain called biofix. Nitrogen treatment was included as a positive control. The results showed that inoculation significantly increased nodule number and weight per plant. There were significant differences among indigenous rhizobia in fixing N. Rhizobia inoculation accounted for 58.91% and 78.95% increase in the amount of N fixed above the control at Koyonzo and Ligala respectively. The strain that fixed the highest amount of N was A6w followed by V2w and W1w at both sites under the dolomitic soil amendment with the values of 14.67, 9.56, 3.53 and 11.37, 8.20 and 1.50 kg N ha-1, respectively at Koyonzo and Ligala sites. Rhizobia inoculation accounted for 80.96% and 47.09% maize yield increase at Koyonzo and Ligala respectively. The best inoculant A6w, gave maize yields of 3.76 and 2.78 t ha-1 at Koyonzo and Ligala, respectively. In conclusion soil amendment with dolomitic lime and inoculating groundnuts with rhizobia strain A6w resulted in increased groundnut and maize yields. This practice can, therefore, be adopted by farmers in western Kenya to improve the productivity of the groundnut maize intercropping systems.
