Soil-derived prokaryotic gut communities of the Japanese beetle Popillia japonica Newman (JB) larval include heterotrophic, ammonia-oxidizing, and methanogenic microbes potentially capable promoting greenhouse gas (GHG) emissions. However, no research has directly explored GHG emissions or eukaryotic microbiota associated with this invasive species. In particular, fungi are frequently insect where they produce digestive enzymes aid in nutrient acquisition. Using a series laboratory field...
To isolate and identify TNT-transforming cultures from explosive-contaminated soils with the ability to produce biosurfactants.Bacteria (pure mixed cultures) were selected based on their transform TNT in minimum media as sole nitrogen source an additional carbon source. bacteria identified by 16S rRNA gene sequencing. transformation rates significantly lower when no or sources added. Surfactant production was enabled presence of TNT. Fourteen able explosive (>50%); these, five showed a high...
Invasive scarab beetles, like the Japanese beetle Popillia japonica Newman (JB), spend most of their lives as larvae feeding in soil matrix. Despite potential importance larval gut microbial community driving behavior, physiology, and nutritional ecology this invasive insect, role biological physicochemical characteristics shaping are relatively unknown. Our objectives were to (1) characterize degree which communities environmentally acquired, (2) examine combined effects region (i.e.,...
Metal oxide engineered nanomaterials (ENMs) in study influenced soil function and microbes, but we found no evidence that changes were caused exclusively by a nano-size effect.
<title>Abstract</title> Pentaerythritol tetranitrate (PETN) is a nitrate ester explosive, true xenobiotic, recalcitrant and persistent compound in the environment. Our main objective was to isolate bacteria from environmental samples collected at an explosive manufacturing plant with capacity transform PETN (100 mg L<sup>− 1</sup>) under aerobic and/or anaerobic conditions. Biotransformation of evaluated using mineral medium without (M-C) additional carbon (M + C) source conditions, Here we...
Abstract Pentaerythritol tetranitrate (PETN) is a nitrate ester explosive that may be persistent with scarce reports on its environmental fate and impacts. Our main objective was to isolate characterize bacteria transform PETN under aerobic anaerobic conditions. Biotransformation of (100 mg L−1) evaluated using mineral medium (M + C) without − additional carbon sources conditions Here, we report the isolation 12 PETN-transforming cultures (4 pure 8 co-cultures) from samples collected at an...
