Article
With the increase in world population and the associated increase in raw material, clean water and energy demands, seeking for innovative and sustainable methods to decrease human-made environmental footprint becomes a task of utmost importance to reduce emissions and waste generation. Uranium-based atomic energy generation has an enormous potentia...
Article
Microplastics (MPs) are among the contaminants that have been of considerable concern in the last decade. One of the most significant contributors to MPs pollution in the environment is the effluent from wastewater treatment plants (WWTP). Previous studies showed that high MPs removal could be achieved in WWTPs. However, the parameters affecting MP...
Article
The Anones Lagoon, located in the Island Municipality of Vieques, Puerto Rico (PR), received extensive bombing by the US Navy during military exercises for decades until 2003 when military activities ceased. Here, we employed shotgun metagenomic sequencing to investigate how microbial communities respond to pollution by heavy metals and explosives...

Pterostilbene, an analog of resveratrol, is a stilbene allelochemical produced by plants to inhibit microbial infection. As a potent antioxidant, pterostilbene acts more effectively than resveratrol as an antifungal agent. Bacterial degradation of this plant natural product would affect the allelopathic efficacy and fate of pterostilbene and thus i...
Preprint
The Anones Lagoon, located in the island municipality of Vieques, Puerto Rico (PR), received extensive bombing during military practices by the US Navy for decades. After military activities ceased in 2003, the bombing range was designated as part of a larger Superfund site by US EPA. Here, we employed shotgun metagenomic sequencing to investigate...
Article
Resveratrol is among the best-known secondary plant metabolites because of its antioxidant, anti-inflammatory, and anticancer properties. It also is an important allelopathic chemical widely credited with the protection of plants from pathogens. The ecological role of resveratrol in natural habitats is difficult to establish rigorously, because it...
Article
Nitroaromatic compounds are typically toxic and resistant to degradation. Bradyrhizobium species strain JS329 metabolizes 5-nitroanthranilic acid (5NAA), which is a molecule secreted by Streptomyces scabies, the plant pathogen responsible for potato scab. The first biodegradation enzyme is 5NAA-aminohydrolase (5NAA-A), a metalloprotease family memb...

Article
Accurate and convenient detection of explosive components is vital for a wide spectrum of applications ranging from national security and demilitarization to environmental monitoring and restoration. With the increasing use of DNAN as a replacement for 2,4,6-trinitrotoluene (TNT) in insensitive explosive formulations, there has been a growing inter...
Article
When anoxic polluted groundwater encounters the overlying vadose zone an oxic/anoxic interface is created- often near the capillary fringe. Biodegradation of volatile contaminants in the capillary fringe can prevent vapor migration. In contrast, the biodegradation of non-volatile contaminants in the vadose zone has received comparatively little att...
Article
Vapor intrusion from volatile subsurface contaminants can be mitigated by aerobic biodegradation. Laboratory column studies with contaminant sources of chlorobenzene and a mixture of chlorobenzene, 1,2-dichlorobenzene, and 1,4-dichlorobenzene showed that contaminants were rapidly degraded in thin reactive zones with high biomass and low substrate c...
Article
Volatile chlorinated compounds are major pollutants in groundwater, and they pose a risk of vapor intrusion into buildings. Vapor intrusion can be prevented by natural attenuation in the vadose zone if biodegradation mechanisms can be established. In this study, we tested the hypothesis that bacteria can use cis-dichloroethene (cis-DCE) or vinyl ch...

Benzalkonium chlorides (BACs) are disinfectants widely used in a variety of clinical and environmental settings to prevent microbial infections, and are frequently detected in non-target environments such as aquatic and engineered biological systems, even at toxic levels. Therefore, microbial degradation of BACs has important ramifications for alle...
Article
Monooxygenation is an important route of nitroaromatic compound (NAC) biodegradation and it is widely found for co-metabolic transformations of NACs and other aromatic pollutants. We investigated the C and N isotope fractionation of nitrophenol monooxygenation to complement the characterization of NAC (bio)degradation pathways by compound-specific...
Article
Much of the microbial activity in nature takes place at interfaces, which are often associated with redox discontinuities. One example is the oxic/anoxic interface where polluted groundwater interacts with the overlying vadose zone. We tested whether microbes in the vadose zone can use synthetic chemicals as electron donors and thus protect the ove...
Article
Plumes of contaminated groundwater often pass through an oxic/anoxic interface when they discharge into surface water bodies. We tested the hypothesis that contaminants recalcitrant under anaerobic conditions but degradable under aerobic conditions can be biodegraded at the interface resulting in the protection of the overlying water. Flow-through...
Article
The quantitative description of enzymatic or abiotic transformations of man-made organic micropollutants in rivers, lakes, and groundwaters is one of the major challenges associated with the risk assessment of water resource contamination. Compound-specific isotope analysis enables one to identify (bio)degradation pathways based on changes in the c...
