Potential of dissimilatory nitrate reduction pathways in polycyclic aromatic hydrocarbon degradation.

This study investigates the potential of an indigenous estuarine microbial consortium to degrade two polycyclic aromatic hydrocarbons (PAHs), naphthalene and fluoranthene, under nitrate-reducing conditions. Two physicochemically diverse sediment samples from the Lima Estuary (Portugal) were spiked individually with 25 mg L of each PAH in laboratory designed microcosms. Sediments without PAHs and autoclaved sediments spiked with PAHs were run in parallel.

Anopheles subpictus carry human malaria parasites in an urban area of Western India and may facilitate perennial malaria transmission.

Background: India contributes 1.5-2 million annual confirmed cases of malaria. Since both parasites and vectors are evolving rapidly, updated information on parasite prevalence in mosquitoes is important for vector management and disease control.

Isolation and characterization of a lipopeptide bioemulsifier produced by Pseudomonas nitroreducens TSB.MJ10 isolated from a mangrove ecosystem.

Pseudomonas nitroreducens TSB.MJ10 exhibiting growth and bioemulsifier production with 0.5% sodium benzoate as the sole carbon source was isolated from a mangrove ecosystem in the vicinity of a petroleum pump.
