“…Earthworms are an important element of the soil environment, they participate in the processes of soil formation, the circulation of organic matter and affect the physical and chemical properties of soil 69 . During the introduction of earthworms into the containers, the escape reaction was observed at the first contact with the soil contaminated with diesel oil, hence the containers were secured with gauze.…”

Fuels and their components accumulate in soil, and many soil organisms are exposed to this pollution. Compared to intensive research on the effect of conventional fuel on soil, very few studies have been conducted on soil ecotoxicity of biofuels. Considering the limited information available, the present study evaluated the changes caused by the presence of biodiesel and diesel fuel in soil. The reaction of higher plants and soil organisms (microbial communities and invertebrates) was analysed. Conventional diesel oil and two types of biodiesel (commercial and laboratory-made) were introduced into the soil. Two levels of contamination were applied—5 and 15% (w/w per dry matter of soil). The plate method was used to enumerate microorganisms from soil contaminated with biodiesel and diesel fuel. Phytotoxicity tests were conducted by a 3-day bioassay based on the seed germination and root growth of higher plant species (Sorghum saccharatum and Sinapis alba). Fourteen-day ecotoxicity tests on earthworm were performed using Eisenia fetida. Based on the results of the conducted tests it was found out that the organisms reacted to the presence of fuels in a diverse manner. As to the microorganisms, both the growth and reduction of their number were noted. The reaction depended on the group of microorganisms, type of fuel and dose of contamination. The lipolytic and amylolytic microorganisms as well as Pseudomonas fluorescens bacteria were particularly sensitive to the presence of fuels, especially biodiesel. Fuels, even at a high dose, stimulated the growth of fungi. Monocotyledonous sugar sorghum plants were more sensitive to the presence of fuels than dicotyledonous white mustard. There was also a significant negative impact of contamination level on plant growth and development. Biodiesel, to a greater extent than conventional fuel, adversely affected the survival and volume of earthworms.

Phytoremediation of polluted environments has received attention and developed rapidly in recent decades. Plant performance assessment is conducted around the effectiveness and efficiency of reducing the concentration of pollutants and certain plant-associated organisms. While supporting these advances, this paper aims to develop integrated phytoremediation as a pollutant treatment reactor involving all processes and multi-kingdoms of organisms, referred to as phytoreactor. The data collected comes from the results of previous studies related to various kinds of phytoremediation processes. Screening and selection of data were based on criteria for differences in plant processes, involvement of various plant-associated organisms, and aesthetics. An arsenic pollutant, one of the most toxic metalloids and ubiquitous, the kingdom’s involvement of plant-associated organisms between aboveground and belowground plant parts. A new perspective in phytoremediation is creating a phytoreactor that integrates three sequential processes. Starting with the containment of toxic pollutants, followed by a primary process consisting of physicochemical and biological processes, and completed by a secondary process in plants, which produces nontoxic environmental media conditions. The primary biological processes are carried out in the rhizosphere and phyllosphere. The involvement of the plant-associated organism kingdom is different in the rhizosphere and phyllosphere due to the suitability of the habitat, the type of pollutant, and the aesthetics of the application of the phytoreactor. Phytoreactor for the remediation of polluted environments involves synergistic multi-kingdoms of plant-associated organisms for specific types of pollutants in the rhizosphere and phyllosphere.

Son yıllarda yapılan araştırmalarda organik atıkların geri kazanılarak farklı sektörlerde (kompost, gübre, enerji, vb) değerlendirilmesi konularında yürütülen araştırmalar artarak devam etmektedir. Bu çalışmanın amacı; kırmızı Kalifornia (Eisenia fetida) solucanının farklı tip yemle beslenmesinin, solucan sayısı ve ağırlığına etkisinin belirlenmesidir. Bu amaçla üç farklı besi ortamında A: fındık atığı (% 100); B: fındık atığı (% 50) + organik çay lifi (% 50); C: fındık fındık atığı (% 30) + organik çay lifi (% 30) + inek gübresi (%20) + gürgen ağacı talaşı (%15) + gazete kağıdı (%5) tesadüfi deneme desenine göre denemeler kurulmuş ve farklı besi ortamlarında Eisenia fetida türü solucanlar 175 gün beslenmiştir. Ortalama değerlere göre en yüksek solucan sayısına 91. günde ve C besi ortamında; en düşük solucan sayısına 133. günde ve C besi ortamında rastlanmıştır. Solucan sayısı bakımından A-B ve B-C besi ortamları arasındaki farkin istatistiksel olarak (p< 0,05) önemli seviyede olduğu belirlenmiştir. Farklı besi ortamlarında 1 adet solucanda en yüksek ağırlığa 49. günde ve C besi ortamında, en düşük solucan ağırlığına ise B besi ortamında rastlanmıştır. Farklı besleme materyallerinde 1 solucanın ortalama ağırlığındaki zamana göre meydana gelen değişimin düzensiz olduğu belirlenmiştir.Anahtar sözcükler: Eisenia fetida, fındık atığı, çay lifi, inek gübresi, solucan sayısı, solucan ağırlığı. Abstract:Recycling of organic waste is extremely important for the sustainable use of natural resources. In recent years, research on organic waste in different sectors (compost, fertilizer, energy, etc.) has been going on. The aim of this study is to determine the effect of different types of feeding materials on the number and total weight of the red worm (Eisenia fetida). For this purpose, experiments were carried out according to the random trial design with four replicates in three diffrent feeding materials; A: hazelnut husk (100%); B: hazelnut husk (50%) + organic tea fiber (50%); C: hazelnut husk (30%) + organic tea fiber (30%) + cow fertilization (20%) + hornbeam sawdust (15%) + newspaper paper (5%) and Eisenia fetida were fed for 175 days. The highest number of worms were found at day 91 and in C feeding materials; while the lowest number of worms was found at day 175 and in B feeding materials. It was determined that the difference between the B and C feeding materials was statistically significant in terms of worm number. In the time dependent change of worm number, it w...
