Insight into how environmental change determines the production and distribution of cyanobacterial toxins is necessary for risk assessment. Management guidelines currently focus on hepatotoxins (microcystins). Increasing attention given to other classes, such as neurotoxins (e.g., anatoxin-a) cytotoxins cylindrospermopsin) due their potency. Most studies examine relationship between individual toxin variants factors, nutrients, temperature light. In summer 2015, we collected samples across...
Abstract Anthropogenic eutrophication threatens freshwater sources used for agricultural irrigation and increases the occurrence risk of cyanotoxins, such as cylindrospermopsin (CYN) saxitoxin (STX). These toxins accumulate in surface waters pose significant health risks, with CYN primarily affecting liver STX targeting nervous system. In this study, dsDNA was immobilized on a pencil graphite electrode (PGE), its interactions were investigated by means electrochemical impedance spectroscopy...
Increasing air pollutants significantly contributes to climate change, requiring innovative mitigation strategies. Microalgae provide a promising solution by absorbing CO₂ and like nitrogen oxides (NOx), sulfur (SOx), ammonia from agricultural industrial emissions, while also generating biomass for biofuels animal feed. This study investigated the effects of light intensity on growth biochemical composition Scenedesmus sp. AQUAMEB-57, Ankistrodesmus AQUAMEB-33, Synechococcaceae AQUAMEB-32...
DNA isolated from environmental samples often contains enzyme inhibitors disruptive to downstream molecular applications. Most of the existing methods cyanobacterial isolation do not effectively eliminate these sediment or cells collected freshwater ecosystems. We describe improved based on xanthogenate-SDS nucleic acid (XS) method Tillett and Neilan (2000). Our provided high-quality that could be amplified in PCR digested with a restriction enzyme. Results were superior several commercial...
One of the most common and widespread bloom-forming cyanobacteria associated with toxin production is Microcystis aeruginosa (Kutzing) Lemmerman. While normally fresh water environments, this toxigenic species has been observed at bloom concentrations in a number major estuaries worldwide. This study examined effect salinity on growth by M. strain PCC 7806 under controlled laboratory conditions. Salt above 12.6 ppt resulted total cessation growth. Toxin was similarly affected, cultures grown...
Bioresources are continually being explored as potential precursors for sustainable supercapacitor electrode materials. In this work, diatom-rich marine mucilage ( MM ) collected from the Marmara Sea, Turkey was used a biomass source and converted to SiO 2 /Carbon nanocomposite /C through pyrolysis acid etching. Diatom frustules acted highly porous silica while algal organic matter delivered carbonaceous part of composite. The natural salts found in served self-activating agent avoided use...
Abstract The mucilage that accumulated in the Sea of Marmara 2021 turned into an environmental disaster threatened not only marine life but also shipping and tourism industries. However, because partially organic structure mucilage, it has potential to be used as additive for polymer films. In this study, bioplastic films were prepared from PVA with a series content 0% 50% by mass, their properties investigated. FT‐IR spectra revealed shift hydroxyl peaks, suggesting interaction between PVA....
Abstract Cylindrospermopsis raciborskii is a potentially toxic cyanobacterium which has become increasingly prominent in algal blooms throughout the USA. Twenty strains of C. isolated from Florida, and one strain Indiana (USA), were tested for ability to produce three toxins, cylindrospermopsin, microcystin saxitoxin using newly developed Polymerase Chain Reaction (PCR) primers Enzyme Linked Immunosorbent Assays (ELISA). None these demonstrated any toxins. Phylogenetic analyses 16S rRNA gene...
ABSTRACT Aphanizomenon ovalisporum is the only confirmed cylindrospermopsin producer identified in United States to date. On other hand, Cylindrospermopsis raciborskii a prominent feature of many lakes Florida and regions States. To see variation cyrB gene adenylation domain sequences possibly discover new producers, we collected water samples for 3-year period from 17 different systems Florida. Positive amplicons were cloned sequenced, revealing that approximately 92% A. -like (>99%...
While global population growth drives increased production efficiency in animal agriculture, there is a growing demand for environmentally friendly practices, particularly reducing air pollutant emissions from concentrated feeding operations. This study explores the potential of cultivating microalgae photobioreactors (PBRs) as an eco-friendly and cost-effective approach to mitigate NH
Mucilage also called sea snot or saliva is a collection of mucus-like organic matter found in the sea. Although not harmful beginning, when mucilage increases over time, it covers creatures and forms thick layers Its existence long duration change oxygen balance seas, reduce biodiversity, fisheries, tourism. Since April 2021, has emerged as both an ecological economical problem Turkey, spreading area kilometers, clogging fishing nets, causing problems marine vessels, disrupting industry....
Microalgae present a massive and untapped natural source of biomass for various applications. The fresh-water microalgae was collected from Lake Uluabat in Turkey. Diatoms, which contain large amounts SiO2 the form cell walls, constituted 60%wt. biomass. SiO2/N-doped carbon nanocomposite (SiO2/NC) obtained by an efficient MgO templating conducted through hydrothermal carbonization successive calcination. Despite its moderate specific surface area (250 m2 g−1) low C content (18%wt.), SiO2/NC...
A major consequence of the sustained degradation coastal environment is progressive eutrophication, which makes Harmful Algal Blooms (e.g. cyanobacteria) more likely to happen and with potential production cyanotoxins may create health hazards. Qatar concerns have been rising following observations blooms in last years. Identifying relevant cyanobacteria species that grow extreme would help keeping records their diversity as well finding strains several positive biotechnological applications...
