Phthalates, widely used in flexible plastics and consumer products, have become ubiquitous contaminants worldwide. This study evaluated the acute toxicity estrogenic endocrine disrupting activity of butyl benzyl phthalate (BBP), di(n-butyl) (DBP), bis(2-ethylhexyl) (DEHP), diisodecyl (DIDP), diisononyl (DINP), di-n-octyl (DNOP) their mixtures. Using a 72 h zebrafish embryo test, LC50 values BBP, DBP mixture six phthalates were found to be 0.72, 0.63 0.50 ppm, respectively. The other four did...
ObjectivesWe carried out a randomized multicentre study in China to investigate whether the clofazimine would improve efficacy of standardized regimen patients with multidrug-resistant tuberculosis (MDR-TB).MethodsPatients MDR-TB managed 17 TB specialist hospitals between September 2009 and 2011 were randomly assigned treatment groups at enrolment. In intervention group, 100 mg per day was added regimen. The primary outcome proportion successful outcomes.ResultsFrom 156 that screened, 74...
With the continuous growth of economic and population, generation food waste has significantly increased in recent years. The disposition waste, typically through incineration or landfill, can lead to severe health environmental problems, accompanied by high additional costs. However, leachate produced from during collection, transportation landfill operations predominantly contains levels nutrients necessary for microalgae growth. integration cultivation into treatment nutrient recycling...
Abstract Harmful algal blooms (HABs) are a global environmental concern, causing significant economic losses in fisheries and posing risks to human health. Algicidal bacteria have been suggested as potential solution control HABs, but their algicidal efficacy is influenced by various factors. This study aimed characterize novel bacterium, Maribacter dokdonensis (P4), isolated from Karenia mikimotoi (Hong Kong strain, KMHK) HAB assess the impact of P4 KMHK's doses, growth phase, mode...
Mangroves are important coastal wetlands along tropical and subtropical regions. Pneumatophore, a kind of aerial root, is among the prominent components mangrove ecosystem, which provides microhabitats for range prokaryotic (bacteria cyanobacteria) microbial assemblages, whose role in maintenance ecology often remains neglected. Very few studies available on pneumatophore-associated microorganisms (PAPMs). The majority them related to microscopic identification cyanobacteria, with very...
Nowadays, citizen science has become increasingly popular, especially in Western countries. In Hong Kong, projects are mostly used for public education, while utilizing scientists published scientific research is very rare. On the other hand, with increasing threats to global water security, Kong requires new adaptation and strategy facing impairment of local freshwater systems. However, unfortunately, number full-scale urban river appears be declining. this regard, can offer an alternative...
Abstract Background Mangrove tannins can participate in wetland biogeochemical cycling. However, their fate and dynamics during leaf litter leaching have yet to be elucidated coastal aquatic environments. Methods By using a simulated microcosm experiment, changes mass tannin compounds, including total phenolics (TP), extractable condensed (ECT), bound (BCT), were examined the litters leachates of four common mangrove species: Kandelia obovata (Ko), Aegiceras corniculatum (Ac), Sonneratia...
Microalgae-based biodiesel is increasingly recognized as an alternative to crop-based biodiesel. In this study, 10 local strains of dinoflagellates collected from Hong Kong waters, including a monoculture and field sample Scrippsiella sp. isolated algal bloom, were evaluated against the performance green alga Tetraselmis suecica. The specific growth rate, biomass production, lipid productivity, fatty acid profile investigated. total content ranged 16.2% 32.2% dry biomass, whereas palmitic...
Abstract Academic research on dinoflagellate, the primary causative agent of harmful algal blooms (HABs), is often hindered by coexistence with bacteria in laboratory cultures. The development axenic dinoflagellate cultures challenging and no universally accepted method suit for different species. In this study, we demonstrated a promising approach combined density gradient centrifugation, antibiotic treatment, serial dilution to generate Karenia mikimotoi (KMHK). Density centrifugation...
Some strains of the dinoflagellate species Prorocentrum hoffmannianum show contrasting ability to produce diarrhetic shellfish poisoning (DSP) toxins. We previously compared okadaic acid (OA) production level between a highly toxic strain (CCMP2804) and non-toxic (CCMP683) P. revealed that cellular concentration OA in CCMP2804 would increase significantly under depletion phosphate. To understand molecular mechanisms, here, we analyzed proteome changes both growing normal condition at...
Several studies have been conducted worldwide in order to develop a more economical method for mass algal cultivation so that cost-effective biomass production can be accessed. One of the directions is reduce costs by using wastewater as nutrient source cell cultivation. The growth ability red-tide causative dinoflagellate species, Prorocentrum minimum, various concentrations local urban was examined this study. highest exponential rate and maximum density (MCD) were achieved when autoclaved...
Kandelia obovata (S., L.) Druce and Sonneratia caseolaris (L.) Engl. are two dominant mangrove species in the subtropical coastlines of Pearl River Estuary, China. The main aim this study was to investigate specific causes K. mortality versus S. vitality on west coast Bao’an, Shenzhen, China propose sustainable management strategies for protection future ecological planting restoration. Results showed that although both mangroves possessed simple unstable community structures, had a more...
Karenia mikimotoi is one of the most damaging ichthyotoxic dinoflagellate species commonly found in China. However, its growth and ichthyotoxicity responses to salinity changes are still largely unknown. In this study, three K. strains, Hong Kong strain KMHK, Japanese NIES2411 New Zealand CAWD133, under different salinities (25 35 ppt), initial algal densities (5 40 thousand cells) phases were investigated. Results indicated that optimum for all strains was 30 ppt. The achieved highest...
Marine medaka is among the most popular models of fish species for ecotoxicology and environmental research proteomic studies are useful tools understanding molecular responses upon exposure to different stressors. The preparation high-quality protein samples key producing two-dimensional gel electrophoresis (2-DE) results analysis. In recent years, Trizol-based extraction has been gaining popularity because its promising performance in 2-DE as well convenience method.Three approaches...
