Transmission of pathogenic microorganisms from contaminated surfaces to hands could cause various diseases. In this study, the microbiological status of shopping carts was investigated in İzmir. To determine where the samples will be taken from and to get user’s opinions about hygiene, a survey was carried out. Total of 100 samples were taken from shopping carts in 20 different markets between February and April, and total viable counts and Escherichia coli counts were applied in samples. Total viable counts of shopping cart handles for 100 samples were found between 0,82– 4,88 log CFU/10 cm2. Coliforms and E.coli were not found in the analysed samples. According to the results, it is seen that the shopping carts have different levels of microbial load; the market environment and the users are effective on these profiles. It has been determined that cleaning and disinfection processes should be applied to improve the hygienic condition of shopping carts and high numbers of microorganisms in the shopping cars might be a potential risk for public health.

Ganoderma lucidum (Curtis) P. Karst., known as “Lingzhi” in China or “Reishi” in Japan, is a well-known medicinal mushroom and traditional Chinese medicine, which has been used for the prevention and treatment of bronchitis, allergies, hepatitis, immunological disorders and cancer. G. lucidum is rarely collected from nature and mostly cultivated on wood logs and sawdust in plastic bags or bottles to meet the demands of international markets. Diverse groups of chemical compounds with pharmacological activities, isolated from the mycelia and fruiting bodies of G. lucidum are triterpenoids, polysaccharides (β-D-glucans), proteins, amino acids, nucleosides, alkaloids, steroids, lactones, lectins, fatty acids, and enzymes. The biologically active compounds as primarily triterpenoids and polysaccharides of G. lucidum have been reported to possess hepatoprotective, antihypertensive, hypocholesterolemic, antihistaminic effects and antioxidant, antitumor, immunomodulatory, and antiangiogenic activities. Several formulations have been developed, patented and used as nutraceuticals, nutriceuticals and pharmaceuticals from G. lucidum’s water or ethanol extracts and rarely purified active compounds. As the result of clinical trials, various products have commercially become available as syrup, injection, tablet, tincture or bolus of powdered medicine and an ingredient or additive in dark chocolate bars and organic fermented medicinal mushroom drink mixes such as green teas, coffees, and hot cacaos. This review has intended to give and discuss recent knowledge on phytochemical and pharmacological compositions, therapeutic and side effects, clinical trials, and commercial products of G. lucidum.

Boron is an important micronutrient for growth and development of crop plants. Plant species differ in their requirement of boron for growth. This study was conducted to determine the effect of boron application on the plant characteristics of maize during early leaf stages. The experiments were conducted in Tel – Kaliş agricultural research area at the Mustafa Kemal University in 2015 and 2016 growing seasons. The field experiments were arranged in a split plot design with three replications. Four boron dosages (control, 4, 6 and 8 mg/m2) were applied at three growing stages (V2, V4 and V2V4 (at V2 and V4 stages in two equal parts) as foliar spray. The results revealed that the effects of foliar application of B were positive but statistically insignificant on plant characteristics. Further researches should be conducted for suitable boron application time at different growth stages of maize.

Burçak Kapur | Yeşim Şahiner
In this study, the effects of two different irrigation regimes (IR100 and IR50) and three different mulch materials (grey, black, transparent and control) on the soil moisture and some pomological characteristics on strawberry (Fragaria x ananassa cv. Fortuna) were examined under Spanish type high tunnels which Turkey is the fourth producer in the world. As a result of the study, soil moisture content under the grey mulch (34.3%) in IR100 (397 mm) applications was highest during the vegetation period and it was followed by black (33.4%), transparent (27.3%) and control (23.9%) applications respectively. The control application is very close to the wilting point in IR50 (288 mm) irrigation regime and the water content increases with mulching via the highest moisture content is in grey (26.3%), black (24.9%) and transparent (23.8%). In addition to the increase in the yield of strawberries with increasing amount of irrigation water, the average fruit weight increased significantly. As well as positive effects such as weed control, soil moisture preservation, of mulching also the fruit size were significantly increased. It was determined that the best fruit sizes were obtained from plants using gray mulch, followed by black mulch which was widely used commercially. The lowest value was obtained from control parcels. The amount of water-soluble dry matter (WSDM) increased significantly with decreasing irrigation water. The mulch types used had no significant effect on WSMD, and the value varied between 7.9 and 8.2%. Even if the effect of irrigation levels on the fruit hardness is insignificant, it is determined that the increasing irrigation water has a positive effect on the hardness of the fruit. Consequently, the most effective agricultural application in different mulch and irrigation water applications is Gary IR100. However, it is important to evaluate this judgment economically in order to be offered to the producer.

Pınar Sevim Elibol
Cucurbita pepo spp. pepo has a unique ability to phytoextract Persistent Organic Pollutants (POPs) such as p,p’-DDE from the contaminated soil to plant compartments. Although the uptake mechanism of the POPs by the plants still remains unknown, p,p’-DDE has been accumulated in the plants grown in the contaminated fields, posing the environmental and human health risks. In this study, p,p’-DDE accumulation was investigated in the plants grown in contaminated soils amended with of 0%(control), 0.1%, 1%, and 10% of biochar produced from activated sludge under greenhouse conditions. The p,p’-DDE concentrations in soil and plant samples were measured by an Agilent 7890A GC with μ-ECD detector. The p,p’-DDE concentrations in roots and shoots of the plants were decreased 94% and 87% compared to the control set, respectively by 10 % biochar amendments which are significantly different from the other sets. On the other hand, p,p’-DDE concentrations in roots were not affected by biochar amendments and measured between 7 ng/g to 8 ng/g for the all sets. Biochar from activated sludge will help sustainable usage of the sludge as soil amendments to the contaminated fields, highlighting the importance of some future studies on the products from waste materials.
