Both high-throughput cultivation dependent and independent tools are required for revealing and characterizing unexplored bacterial diversity and understanding their interactions with biotic and abiotic environmental factors. Castro et al. (2010) showed that precipitation influences the abundance of Proteobacteria and Acidobacteria in the soil environment. pH has been one of best studied abiotic factors affecting soil microbiota composition and function, both at local and continental scales (Lauber et al., 2009; Rousk et al., 2010; Chu et al., 2010). Research on soils from the Peruvian Amazon showed that both diversity and composition of soil bacteria were strongly affected by a diverse range of ecosystem parameters including mean average temperature, potential evapotranspiration, latitude and soil pH. They concluded that pH was the best predictor of both soil bacterial diversity and richness in acidic soils (Fierer & Jackson, 2006). On the other hand, more recently Faoro et al. (2010) showed that the bacterial diversity in southern Brazilian Atlantic forest soils was influenced by altitude, phosphorus and Ca +2 /Mg +2 , whereas pH had no significant effect. Lauber et al. (2009) indicated that the bacterial diversity is affected by the pH and soil texture, whereas the fungal diversity was strongly influenced by nutrient availability. Measurement of membrane phospholipid fatty acid (PLFA) profiles is a useful tool for the characterization of microbial composition, and it has been widely used to assess the effect of various physical-chemical parameters such as, pH, soil texture, aeration and the availability of nutrients, on the microbial diversity in soil

Totaly 33 different feeds supplied from 15 trout farms of Adana (Turkey) were analysed for moulds and aflatoxins (AFB1, AFB2, AFG1 and AFG2) between July-December 2010. To identify mould counts; the samples were incubated in the aerobic conditions at 25 ± 1 °C for five days by using Dichloran Rose Bengal Chloramphenicol Agar (DRBC). Aflatoxins were determined by using liquid-solid extraction and recoveries were obtained 70.00% to 112.20%. The precision of measured values of mould and aflatoxin analysis methods was calculated with the results of repeatability and reproducibility. The bias, expressing the accuracy value, varies between 4.312 and 12.909. Although moulds were found in 12 of 33 analysed samples (36.30%): aflatoxins were determined 8 out of 33 analysed samples (24.25%). Positive sample’s range were 3.08-4.86 log10 ko...

The virus, which spreads rapidly via respiratory tract and contact, causes many people to die. Biological warfare claims are still on the agenda as the reason for the emergence of the virus; However, population growth, industrialization, deforestation, urbanization, reduction of green areas, fossil fuels such as oil, coal and natural gas, which have found excessive doses since the 18th century, pollute the air by increasing carbon emissions in the atmosphere and cause global climate change. These human activities facilitate the spread of the epidemic by wild animals, which are known to be effective species in transporting viruses, while dragging them to find new habitats because they disrupt their natural habitats. It has been determined

Although extensive monitoring and controlling of tap water, people state that they do not consume tap water in Turkey. Realization of minor changes in parameters such as odour, colour and taste or misdirected news on the visual media led public to use either bottled water or household water filtration systems. The aim of the present study was to reveal the present situation of contamination in the waters obtained from residential water filtration device by analyzing physical, organoleptic, some chemical and microbiological parameters. Physicochemical properties of taste, colour, odour, turbidity, pH, temperature, conductivity, total hardness, iron, aluminum and nitrate values of 300 samples (inlet and outlet of water) were evaluated. Within the scope of microbiological analysis of Clostridium perfringens, Pseudomonas aeruginosa, coliform, Escherichia coli, colony counting at 22°C and 37°C were examined. The results of the physicochemical analysis showed that tested values stated in the regulation. Microbiological results of samples did not comply with required standards. In particular, E. coli outbreaks showed that water contamination and disinfection procedure were inadequate. According to the paired t test results, we found that E. coli, colonic counts at 22°C and 37°C were statistically significant (p < 0.05). As a conclusion, household water filtration devices cannot demonstrate the performance that they show for chemical pollution when it comes to microbiological contamination.

Strain ES5 fermented glycerol to 1,3-propanediol as main product, and lactate, acetate and formate as minor products. The strain was phylogenetically closely related to Tricho-coccus flocculiformis; the rRNA gene sequence simi-larity was 99%. However, strain ES5 does not show the typical growth in chains of T. flocculiformis. More-over, T. flocculiformis does not ferment glycerol. Strain ES5 used a variety of sugars for growth. With these substrates, lactate, acetate and formate were the main products, while 1,3-propanediol was not formed. The optimum growth temperature of strain ES5 ranges from 30–37°C, but like several other Tri-choccoccus strains, strain ES5 is able to grow at low temperature (< 10°C). Therefore, strain ES5 may be an appropriate catalyst for the biotechnological produc-tion of 1,3-propanediol from glycerol at low ambient temperat...

However because of the threat of water-borne diseases, many still think that it is not wise to drink tap water. This has increased the demand for "pointof-use" water treatment systems in Turkey. This study aims to assess public preferences on drinking municipal tap water amongst the inhabitants of Adana, Turkey, and to establish the awareness of filter replacement of point of use water treatment systems. 5,139 individuals were interviewed (women 44% and men 56%) and a high percentage of the respondents expressed a preference for using tap water rather than bottled or filtered water. The users of filtered water stated that they preferred the filtration system to remove the pathogens and to change the odor/taste/color of the water. As the age of consumers increased, the bottled and filtered water utilization increased while tap water utilization decreased. In terms of gender, men had a higher ratio to prefer drinking tap water than women. Consumption of tap water decreased as education level and income increased.

Bacterial communities are known to have the most effective role in biological deterioration in stones. The ancient city of Anazarbos (Anavarza), chosen as the study area, is the 1st Degree Archaeological Site in the vicinity of Dilekkaya Village, Kozan District, about 70 km north of Adana. The microbiological, chemical, mineralogical, and microstructural properties of stone samples taken from different places were studied in this research. Samples were taken from i) where no deterioration occurred, ii) where different forms of deterioration were observed, iii) archaeological deposits, iii) archaeological deposits that came from deteriorated stone samples area. Spectroscopic, thermal, and microscopic techniques applied included: X-Ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy-Energy Dispersive System (SEM-EDS), Thermogravimetric Analysis/Differential Thermal Analysis (TG/DTA). The bacterial biodiversity was analyzed by the application of Illumina-based next-generation sequencing methods. Results show intense biological colonisations with clay minerals on limestone surfaces. A patina of clay minerals was observed on newly excavated stone surfaces, while biological colonisations have not yet intensified. The metabarcoding analysis showed 15 bacterial phyla. The Proteobacteria and Actinobacteria were the most abundant phyla in both stones and archaeological deposits samples. Human activity (intensive agriculture, animal husbandry), accumulation of rainwater in excavated areas adversely affects stones, which leads to acceleration of biological deterioration in stones. Thus, all features of the site require multi-faceted studies prior to unearthing of archaeological remains.

Realization of minor changes in parameters such as smell, color or taste or misdirected news on the visual/written media led public to use bottled water or residential water filtration systems in the cases of crowded households for economical reasons to clean the tap water instead of buying bottled water. The aim of this study was to determine the microbiological and chemical state of water in the residential water filtration systems which are widely used in everyday life. Physicochemical properties of taste, color, odor, turbidity, pH, temperature, conductivity, total hardness, and iron and nitrate values of 300 samples were evaluated at the Adana Public Health Laboratory. In the microbiological analyzes of 300 samples , the presence of Clostridium perfringens, Pseudomonas aeruginosa, Coliform, Escherichia coli, colony counting at 72 ° C at 22 ° C and colony counting at 37 ° C were examined in the Adana Pu...

In the case of developing countries such as Turkey, inclusion in the UNESCO World Heritage List helps generate much needed income through grants and tourism activity. There are currently eighteen sites in Turkey that are on the World Heritage List, and another eighty-three on the tentative list, the majority of which have been inscribed in the last decade. However, such an acceleration of attempts to promote sites as world heritage because of their attributes can also lead to conflicts about the values of the sites, project management, community enhancement and the degree to which important related studies are carried out. The ancient city of Anazarbos is one that exemplifies such a situation. The site's history as cultural and military cross-roads in the Cilicia region, and the potential to reveal those who successively inhabited and controlled it paved the way to its inclusion in the tentative list in 2014 by meeting the outstanding universal values. In this context, this study aims to provide an accurate background of in the hope of raising its status so that further research can be carried out. The study first presents the case for the concept of world heritage and then offers a thorough assessment of the city in terms of its heritage significance. Following a discussion on the values associated with the site and the changing dynamics after its inclusion to the list, the study concludes with suggestions for its holistic conservation.

The projections on the effects of climate change are foreseen to be more severely affected by the Mediterranean Basin. The expected effects of climate change all over the world include increasing the number and severity of climate-related natural disasters such as floods, fires, storms and earthquakes; there are changes in precipitation pattern, emergence of invasive species due to excessive heat waves and global epidemics. In the last twenty years, climate disasters caused annual average 462 million of dollars’ economic damage. Therefore, it is really important in this struggle for everyone to take responsibility.

People's curiosity to access this information leads to tourism activity, in which caves constitute a significant place as sources of geotouristic attractions. In the case of Turkey, caves can also be considered as the major source of tourist attractions and thus economic gain providers for local communities. Focusing on the contribution of tourism to the economy, most local authorities allow tourism activity for the caves without adequate research. This leads to the construction of buildings for the needs of visitors and the installation of walking pathways, ladders, and luminaires inside the caves, which are in most cases harmful to cave ecosystems. Located on the Mediterranean coastline of Turkey, Gilindire Cave presents such a case. Unlike other caves in Turkey, it is among three caves that were found to occur in the Cambrian limestone caves literature. Thus, any data to be detected in this environment is of scientific importance. However, service buildings constructed in the upper elevation of the cave and visitor stairs and luminaires installed in the interior constitute major threats to accessing this valuable information. In this context, the study aims to examine the caves in the scope of geotourism and tourism-led constructions through the example of Gilindire Cave. As a result, the study underpins the importance of diligent investigation of cave ecosystems prior to any tourism-led activity and principles for the service structures to be built in such geoheritage sites.

Gilindire Cave, located in Mersin; Turkey, contains samples from Ice Age and is the only place known to represent evidence of the last climate changes in in the Eastern Mediterranean. Therefore, Gilindire Cave distinguishes itself from other caves in Turkey with its "representative" and "individual" features. In this study bacterial load of Gilindire Cave was investigated by using culture dependent and culture independent methods. Samples were cultured on R2A petri plates and distinct looking colonies were isolated. After isolation, 16S rRNA PCR analysis was performed. 58 isolates were obtained after cultivation experiments. However, further investigation was completed on 30 individual isolate due to elimination of isolates. Crystal formation was investigated with B-4 media and it was seen that 3 of the isolates was unable grow on this media while the rest 27 were able to grow successfully. Twenty of the isolates were chosen and send to analysis. Most abundant phyla included Actinobacteria (39%) followed by Proteobacteria (%33), Firmicutes (17%) and Bacteriodetes (5,5%) as well as uncultured organism (5,5%) was found, usable results could not be obtained from two of the isolates.

While aerobic SLES degradation is well studied, little is known about the fate of this compound in anoxic environments, such as denitrification tanks of WWTPs, nor about the bacteria involved in the anoxic biodegradation. Here, we used SLES as sole carbon and energy source, at concentrations ranging from 50 to 1000 mg L(-1), to enrich and isolate nitrate-reducing bacteria from activated sludge of a WWTP with the anaerobic-anoxic-oxic (A(2)/O) concept. In the 50 mg L(-1) enrichment, Comamonas (50%), Pseudomonas (24%), and Alicycliphilus (12%) were present at higher relative abundance, while Pseudomonas (53%) became dominant in the 1000 mg L(-1) enrichment. Aeromonas hydrophila strain S7, Pseudomonas stutzeri strain S8, and Pseudomonas nitroreducens strain S11 were isolated from the enriched cultures. Under denitrifying condit...

Reduced dissolved organic carbon and increased dissolved oxygen concentrations in surface water and reduced total organic carbon and total nitrogen content in the sediment were recorded in the post-WWTP samples. Pyrosequencing of bacterial 16S rRNA gene fragments in sediment cores showed reduced relative abundance of heterotrophs and fermenters such as Chloroflexi and Firmicutes in more oxic and nutrient poor post-WWTP sediments. Similarly, quantitative PCR analysis showed 1-3 orders of magnitude reduction in phylogenetic and functional genes of sulphate reducers, denitrifiers, ammonium oxidizers, methanogens and VC-respiring Dehalococcoides mccartyi. In contrast, members of Proteobacteria adapted to nutrient-poor condi...
