Ecological Dynamics in the Face of Climate Change: Exploring Organisms, Habitats, and Behavioural Adaptations is a comprehensive exploration of the profound impacts of climate change on ecosystems and living things. It encompasses a broad spectrum of topics, from the pivotal role of microorganisms in combating global warming to the dramatic changes...

Polygonum cognatum Meissn, a perennial herbaceous belonging to the Polygonaceae family, is an aromatic plant. High‐performance liquid chromatography/diode array detector method was developed and validated for the phytochemical analysis of the plant. Also, various methods were used to investigate the antioxidant, antimicrobial, and cytotoxic activit...

Skates and rays, which are widely encountered in the by-catch of fisheries activities from the Sea of Marmara and banned for sale by regulation, are species that are discarded if caught. For this reason, in our study, we aimed to determine the bioactive potentials of these species, considered fishing waste, by investigating the skin secretions and...

The fact that foods can provide additional medicinal health benefits beyond basic energy requirements and nutritional needs for survival, has been proven through rigorous scientific researches over the years. Although Turkey is historically believed to be the ancient origin of a decent number of fermented probiotic foods and beverages, there is st...

Turkey is a home country for a good number of fermented beverages derived from milk, cereals, fruits and vegetables, and several studies have reported the probiotic potentiality of these beverages. Probiotics, otherwise known as beneficial microorganisms possess the ability to exert antimicrobial effects, which is one of the most important selectio...

İnsanların uzun vakit geçirdikleri kapalı olanlar olan okul, ev, hastane gibi iç mekanlarda mikroorganizmalar duvar, zemin gibi yüzeylerde kolonize olmaktadır. Yüzeylere temas mikroorganizmalar ile çapraz kontaminasyonlar oluşturmakta ve buna bağlı olarak enfeksiyonlar meydana gelmektedir. Enfeksiyonları önlemek için yüzeyler çeşitli yöntemlerle an...

Biofilms in industrial cooling tower systems is an important problem. The importance of the surface material in the response to an oxidizing biocide (chloramine T trihydrate) was substantiated in our study. Polyvinyl chloride (PVC; cooling tower fill material), stainless steel (SS; cooling tower construction material) and glass (G) surfaces were co...

The following correction should be noted to the Acknowledgment section of this article: “Project numbers T-953/06102006” should instead read “Project numbers FYL-2016-21280”.

This study aimed to investigate the antibiofouling activity of 3-(trimethoxysilyl)-propyl, alkyldimethylammonium chloride-based (SilQUAT)-treated glass fiber-reinforced polyester (GFRP) composite panels in model cooling tower system. All surface characterization analyses were performed by using FTIR and XPS and showed that surface chemical composit...

A model cooling tower system was experimentally seeded with Legionella pneumophila and real industrial cooling tower (CT) water has been run at the closest to full-scale system operating conditions. The water/biofilm samples were taken from the model system monthly, and the effectiveness of the different concentrations of Chloramine T trihydrate bi...

Cooling towers are potential sources for the amplification and dissemination of legionellae. Public health risks posed by legionellae may be eliminated via preventive methods. Biocide application in cooling towers is the most common and critical prevention strategy against legionellae. Successful results may be achieved by pre-determining microbial...

Biofilm formation in recirculating water systems such as cooling towers lead to many undesired conditions in terms of public health concern, operational damage and economic loss. Accumulation of pathogenic bacteria (i.e. Legionella pneumophila), increased resistance to antimicrobial compounds, a significant energy loss by increasing heat transfer r...

Cooling towers are heat rejection systems that are used in some industrial applications, and they have the potential to develop infectious concentrations of Legionella pneumophila. SANIPACKING® cooling tower fill material and standard polypropylene fill material were compared in terms of biofilm formation potential and anti-Legionella activity with...

Cooling towers are considered as amplifier and disseminator sources for spp. despite preventive treatments. Information which was obtained from biocidal tests could improve the effectiveness of treatments. Therefore, the choice of appropriate biocides and the applying of biocides in correct dosages and contact times are important. Various oxidizing...

Biofilms are complex communities of microorganisms attached to surfaces or associated with interfaces. Since biofilm formation is influenced by the type of surface materials, in the current study it was aimed to compare copper, stainless steel, galvanized stainless steel, polyvinyl chloride, polyethylene, polypropylene, ceramic and glass surfaces f...

The antibacterial materials such as fabrics, cloths are became important to avoid cross infection by pathogenic microorganisms, especially bacteria such as Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae, to control the infestation by microbes, and to arrest metabolism in microbes in order to reduce the formation odour. Textiles f...

Effectiveness of Chloramine T trihydrate (N-chloro-p-toluene sulfonamide) on both planktonic and sessile populations of different Legionella pneumophila strains was assessed. Although Chloramine T is a recommended commercial formulation for disinfecting cooling towers, there is a lack of published data about the efficacy of this compound against bo...

Efficacy of Gemacide PN-50TM (a quaternary ammonium compound) as a commercial formulation recommended for disinfecting heat exchangers was determined for both planktonic and sessile populations of variousLegionella pneumophila strains. The quaternary ammonium compound (QAC) was preferred as an alternative due to the emerging resistance of potential...

A hundred Enterococcus strains were isolated from seawater samples collected from coastal areas of Istanbul. Isolates were identified to the species level using standard biochemical tests specified by Facklam and Collins. The species distribution was as follows Enterococcus faecalis (96%), Enterococcus gallinarum (3%) and Enterococcus solitarius (1...
