Brevibacterium spp. are aerobic, nonbranched, asporogenous, gram-positive, rod-shaped bacteria which may exhibit a rod-coccus cycle when cells get older and can be found in various environments. ​Several Brevibacterium species have industrial importance and are capable of biotransformation of various contaminants. Here we describe the draft genome sequence of Brevibacterium epidermidis EZ-K02 i...

While developed societies made significant progress in reducing the discharge of many wastes— including industrial wastes, organic matter in sewage, sludge, contaminated sediments and other material dumped at sea, toxic compounds, and oil— into coastal waters, nutrient over-enrichment intensified and spread widely among the planet’s coastal environments during the last half of the 20 century. T...

Aquatic nematode-trapping hyphomycetes have rarely been studied. The current study examined 1000 waterlogged soil samples in order to systematically investigate resources of aquatic nematode-trapping hyphomycetes and to compare species diversity and community similarities in polluted and unpolluted aquatic environments. Many nematode-trapping hyphomycetes live in shallow freshwater (at a water ...

Today, the role of aquaculture in food production, economic development and food security is well known, but this industry still faces many challenges, including the prevalence of pathogens in farming systems. So far, various chemical, physical and biological methods have been used to control and prevent the spread of pathogens in farming environments, some of which are unfortunately not widely...

Phytoremediation, a plant based green technology, has received increasing attention after the discovery of hyperaccumulating plants which are able to accumulate, translocate, and concentrate high amount of certain toxic elements in their above-ground/harvestable parts. Phytoremediation includes several processes namely, phytoextraction, phytodegradation, rhizofiltration, phytostabilization and ...

The transgenerational consequences of environmental contaminant exposures of aquatic vertebrates have the potential for broad ecological impacts, yet are largely uninvestigated. Bisphenol A (BPA) and 17a-ethinylestradiol (EE2) are two ubiquitous estrogenic chemicals present in aquatic environments throughout the United States and many other countries. Aquatic organisms, including fish, are expo...

Pond-breeding amphibians exhibit large intra- and interspecific differences in the duration of the aquatic larval phase. In contaminated aquatic environments, a prolonged larval phase means prolonged exposure to pollutants and, potentially, more severe toxic effects. In the laboratory, we tested this hypothesis by exposing green frog larvae (Rana clamitans) to commercial clean sand (control), s...
