Selective pseudosolubilization capability of

Fei HUA, Hongqi WANG

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 4,   Pages 539-551 doi: 10.1007/s11783-013-0498-z

Abstract: Pseudosolubilized ability of sp. DG17 on -alkanes, role of biosurfactants in -octadecane uptake and trans-membrane transport mechanism of -octadecane were studied by analyzing amount of pseudosolubilized oil components in water phase, and the fraction of radiolabeled C -octadecane in the broth and cell pellet. GC-MS results showed that pseudosolubilized oil components were mainly C to C of -alkanes. In -octadecane broth, pseudosolubilized -octadecane could be accumulated as long as pseudosolubilized rate was faster than mineralization rate of substrate, and the maximum concentration of pseudosolubilized -octadecane achieved to 45.37 mg·L . All of these results showed that sp. DG17 mainly utilized alkanes by directly contacting with pseudosolubilized small oil droplets in the water phase. Analysis of C amount in cell pellet revealed that an energy-dependent system mainly controlled the trans-membrane transport of -octadecane.

Distribution and removal of antibiotic resistance genes during anaerobic sludge digestion with alkaline

Mengli Wang, Ruying Li, Qing Zhao

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 3, doi: 10.1007/s11783-019-1127-2

Abstract:

Sludge digestion is critical to control the spread of ARGs from wastewater to soil.

Fate of ARGs in three pretreatment-AD processes was investigated.

UP was more efficient for ARGs removal than AP and THP in pretreatment-AD process.

The total ARGs concentration showed significant correlation with 16S rRNA gene.

The bacteria carrying ARGs could be mainly affiliated with Proteobacteria.

Degradation of extracellular genomic, plasmid DNA and specific antibiotic resistance genes by chlorination

Menglu Zhang, Sheng Chen, Xin Yu, Peter Vikesland, Amy Pruden

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 3, doi: 10.1007/s11783-019-1124-5

Abstract:

Extracellular DNA structure damaged by chlorination was characterized.

Integrity of extracellular ARG genetic information after chlorination was determined.

Typical chlorine doses will likely effectively diminish extracellular DNA and ARGs.

Plasmid DNA/ARGs were less readily broken down than genomic DNA.

The Bioanalyzer methodology effectively documented damage incurred to DNA.
