Characterization of a 2,2-dichloropropionic acid (2,2-dcp) degrading alkalotorelant bacillus megaterium strain bhs1 isolated from blue lake in Turkey

Yılmaz KAYA

An acid, 2,2-dichloropropionic acid (2,2-DCP) is an active ingredient in herbicide (DalaponÂ®). Using 2,2-DCP as a model substrate, an alkalotolerant bacterium was successfully isolated from the Blue Lake, Turkey. This bacterium is a potential bioremediation agent of recalcitrant xenobiotic halogenated compounds. This study aimed to prove the efficacy of the alkalotolerance Bacillus megaterium BHS1 in degrading 2,2-DCP as the sole source of carbon. Biolog GEN III system and 16S rRNA analysis were used for the identification of the bacterium. It was discovered that the strain BHS1 is Bacillus m ...Более

Sorption characteristics of zeolite and bentonite natural adsorbents modified complex

Zarlık MAYMEKOV

The main objective of our study is to obtain a complex compound from natural adsorbents to purify wastewater with simultaneous sorption of chemical and microbiological substances contained therein, which contribute to disinfection and softening of water, increasing the degree of treated water saturation with calcium, magnesium salts and trace elements, while not requiring the use of sophisticated equipment. The technical result is to create a complex of adsorbents with the sorbing ability of chemical and microbiological pollution, disinfecting and softening water, enriching it with calcium ion ...Более

The Effects of Arbuscular Mycorrhizal Fungi and Lead (Pb)Applications on Eggplant Seedling Growth and Nutrient Uptake

Mustafa PAKSOY | Önder TÜRKMEN

There are many factors, which negatively affect plant development. One of these factors is lead (Pb), which causes toxic effects on plants during the seedling period. Mycorrhizas (AMF) contribute positively to plant growth. In eggplant seedlings, it has been researched whether to tolerate the negative effects of lead with mycorrhizas. In the study, Gigaspora margarita (Gm) and Glomus intraradices (Gi) mycorrhizal races were applied before seeds were sown. After the first true leaves appeared, 5 different doses of Pb (0, 100, 200, 400 and 800 ppm) were given. As a result, the earliest true leaf ...Более

A Comparison of Various Ecological Indexes for Environmental Assessment of Vulnerable Mountain Ecosystems

Nurzat TOTUBAYEVA | Kanatbek KOCOBAYEV | Gülbübü KURMANBEKOVA | Ciyde TOKPAEVA

The aim of this work was to compare various ecological indexes to assess the state of urbanized ecosystems of the Issyk-Kul region in the Kyrgyz Republic. Soil samples were analyzed for Pb, Zn, Fe, Cu and Cd using AAS. Heavy metal contamination status was assessed using indexes for enrichment factor, geo accumulation, contamination factor, degree of contamination, pollution load, potential ecological risk and integrated risk using the Triad approach. Results show marked variations of heavy metal concentrations within the study area. The concentrations of heavy metals in soils of Issyk-Kul had ...Более

RK PROBABILISTIC HYDROGEOLOGICAL MAP

Kanatbek KOCOBAYEV

Hydrogeological maps are currently one of the most important elements of the image of the hydrogeological situation in both regional and local representation. In accordance with the existing instructions, they are compiled on the basis of t opographic, geological and tectonic maps of various scales based on the results of hydrogeological surveys and reflect the boundaries of the distribution of aquifers and complexes, confined, as a rule, to geological-stratigraphic and tectonic formations and their real manifestations on the ground (sources, wells, drilling wells). In addition to the General ...Более

Boron-containing magnetic nanoparticles from Co, Ni, and Fe chloride salts and their catalytic performances on 4-nitrophenol reduction

Nahit AKTAŞ

In this study, magnetic metal nanoparticles (MNP) were prepared by using Fe, Co and Ni ions and NaBH4 as reducing agents in oil-in-water microemulsion system. The prepared MNP were used as catalyst in 4-Nitro phenol (4-NP) reduction to 4-Aminophenol (4-AP). It was found that magnetic Co MNP performed superior catalytic performances than Fe and Ni MNP for 4-NP reduction. The catalytic reduction experiments revealed that as the concentration of reducing agent, NaBH4 that was used in the preparation of Co MNP was increased, the complete conversion time for 4-NP to 4-AP was decreased as the sizes ...Более

Ammonia removal from wastewater by air stripping and recovery struvite and calcium sulphate precipitations from anesthetic gases manufacturing wastewater

Mehmet KOBYA

Anesthetic gas plant wastewater (AGPW) contains high concentrations of ammonia (NH3-N) and sulphate ions, which is known to results in severe environmental pollution in aquatic ecosystems without treatment. In the first stage of this study, a lab-scale investigation was done to improve removal of ammonia from AGPW by air stripping and struvite (or MAP: magnesium ammonium phosphate) precipitation processes, separately. The main operating parameters such as pH, air flow rate (L/min) and operating time were optimized for air stripping. The theoretical amount of removed ammonia via the air strippi ...Более
