Article
Full-text available
The explosive hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), a major component of munitions, is used extensively on military training ranges. As a result, widespread RDX pollution in groundwater and aquifers in the United States is now well documented. RDX is toxic, but its removal from training ranges is logistically challenging, lacking cost-effe...

Main conclusion Transgenic western wheatgrass degrades the explosive RDX and detoxifies TNT. Contamination, from the explosives, hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine (RDX), and 2, 4, 6-trinitrotoluene (TNT), especially on live-fire training ranges, threatens environmental and human health. Phytoremediation is an approach that could be used t...

The indoor air in urban homes of developed countries is usually contaminated with significant levels of volatile organic carcinogens (VOCs), such as formaldehyde, benzene, and chloroform. There is a need for a practical, sustainable technology for the removal of VOCs in homes. Here we show that a detoxifying transgene, mammalian cytochrome P450 2e1...

Key message: Expression of the bacterial nitroreductase gene, nfsI, in tobacco plastids conferred the ability to detoxify TNT. The toxic pollutant 2,4,6-trinitrotoluene (TNT) is recalcitrant to degradation in the environment. Phytoremediation is a potentially low cost remediation technique that could be applied to soil contaminated with TNT; howev...

The deposition of toxic munitions compounds, such as hexahydro-1, 3, 5-triniitro-1, 3, 5-trizaine (RDX), on soils around targets in live-fire-training ranges is an important source of groundwater contamination. Plants take up RDX but do not significantly degrade it. Reported here is the transformation of two perennial grass species, switchgrass (Pa...
Article
The study describes the diversity of actinobacteria isolated from the marine sponge Iotrochota sp. collected in the South China Sea. Species and natural product diversity of isolates were analyzed, including screening for genes encoding polyketide synthases (PKS) and nonribosomal peptide synthetase (NRPS), and 16S rRNA gene restriction fragment len...

Full-text available
This study describes actinobacteria isolated from the marine sponge Haliclona sp. collected in shallow water of the South China Sea. A total of 54 actinobacteria were isolated using media selective for actinobacteria. Species diversity and natural product diversity of isolates from marine sponge Haliclona sp. were analysed. Twenty-four isolates wer...
Article

The alien addition line TAI-27 contains a pair of chromosomes of Thinopyrum intermedium that carry resistance against barley yellow dwarf virus (BYDV). A subtractive library was constructed using the leaves of TAI-27, which were infected by Schizaphis graminum carrying the GAV strain of BYDV, and the control at the three-leaf stage. Nine differenti...

The journal Environmental Science and Pollution Research (IF 4.223) (ISSN 1614-7499) is currently running a special issue entitled "Special Issue on Nano-bioremediation Approaches for Sustainable Agriculture". As we are acting as guest editors and inviting you to consider submitting your full paper to this special issue. Submission Period: 30 September 2021 up to 31 January 2022 The environmental pollution mediated by a variety of organic, inorganic, persistent, and non-persistent pollutants has a substantial impact on agriculture. To resolve this global concern, nanotechnological advances could provide significant potential for decontamination of polluted sites for sustainable agriculture. The critical appraisal on the integration of nanotechnology with bioremediation can be used for a variety of reasons, including the fact that nanoparticles have a large surface area per unit mass, which accelerates the remediation process to minimize pollutant concentrations to risk-based thresholds while also decreasing secondary environmental impacts. The prestigious journal “Environmental Science and Pollution Research” (ESPR) serves the international community in all areas of environmental research, especially on microbial bioremediation, phytoremediation and ecosystem restoration aspects. This special issue could be interesting for wide range of “ESPR” international scientific community and will improve the scientific gaps of nanotechnology-based remediation to make it less hazardous and reusable. In a nutshell, the special issues editors believe that the final outcomes distinctively will provide perspective on nanobioremediation, as well as detailed gaps and unforeseen issues. This special issue will be combined with original research and critical reviews related to environmental protection, resource conservation, soil remediation, sustainable agriculture, climate change mitigation and carbon emission reduction through nanotechnological approaches. All full papers must be submitted through the Editorial Manager system (https://www.editorialmanager.com/espr/default.aspx). When submitting your manuscripts, please specify that your paper is a contribution for the Special Issue entitled “Nano-bioremediation Approaches for Sustainable Agriculture”. Please also refer to the Submission Guidelines (via https://www.springer.com/journal/11356/submission-guidelines) prior to submission for the proper format of your manuscripts.

In this proposal, we propose a new approach: we will improve the ability of common houseplants to re-move toxins from air using biotechnology. Our goal is to engineer houseplants to break down all of the most common gaseous air pollutants found in American homes. Using methods we have developed for reducing water and soil pollution with transgenic plants, we will engineer houseplants to detoxify by deg-radation the common air pollutants found in American homes.
