Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

Polymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Time‐Resolved Effects of Cold Atmospheric Plasma on E. coli GW‐AmxH19 Transcriptome and Proteome in an Emulated Wastewater Environment

PROTEOMICS, EarlyView.
ABSTRACT Cold atmospheric plasma (CAP) is effective against a variety of microorganisms. Here, we described effects on an Escherichia coli strain isolated from hospital wastewater caused by treatment with physical plasma. E. coli GW‐AmxH19 was incubated in artificial wastewater and treated for 15 min with CAP.

A mathematical model for genetic regulation of the lactose operon

, 2005
In this paper we construct a mathematical model for the genetic regulatory network of the lactose operon. This mathematical model contains transcription and translation of the lactose permease (LacY) and a reporter gene GFP.

Floristic condition drives differential response to cultural burns in grassy woodlands for ectomycorrhizal and arbuscular mycorrhizal fungi

PLANTS, PEOPLE, PLANET, EarlyView.
Cultural burns are a critical Indigenous land management practice with diverse cultural and biodiversity benefits, now being reintroduced by Indigenous communities to Australian grassy woodlands after long post‐colonization suppression. How these burns influence soil fungi, critical partners in plant nutrition, remains poorly understood.

Herbal Therapeutics in Osteoporosis: Mechanisms, Evidence, and Translational Potential

Phytotherapy Research, EarlyView.
Schematic overview of bone remodeling dysregulation in osteoporosis and the multi‐target protective role of herbal therapeutics. ABSTRACT Osteoporosis is a chronic bone disease marked by reduced density and increased fracture risk. Current treatments face limitations in safety, efficacy, and long‐term adherence, prompting interest in alternative ...

Supplementary Material for: Fucose-Mediated Transcriptional Activation of the fcs Operon by FcsR in Streptococcus pneumoniae

, 2015
In this study, we explore the impact of fucose on the transcriptome of S. pneumoniae D39. The expression of various genes and operons, including the fucose uptake PTS and utilization operon (fcs operon) was altered in the presence of fucose.

Larvae of the Solitary Bee Epicharis bicolor Are a Rich Source of Yeasts, Including Four Novel Species of the Genera Starmerella, Wickerhamiella and Zygoascus

Yeast, EarlyView.
Four novel yeast species are described associated with larvae of the ground‐nesting solitary bee Epicharis bicolor in Brazil. These yeasts are described based on sequencing of the ITS‐5.8S region and D1/D2 domains of the large subunit of the rRNA gene and phylogenomic analyses.

Alternative transcriptional start sites of the PQS operon.

, 2012
A) Model of the PQS biosynthetic operon (pqsABCDE) with the three alternative TSS indicated by arrows. The TSS are named by the next downstream gene with subscripts indicating the TSS position relative to the start of the associated gene.

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

Characterization of the Bacillus subtilis pur operon

, 1988
The Bacillus subtilis pur operon was characterized to better understand genetic organization and regulation in this gram positive bacterium. Over 13 kilobase pairs of DNA containing the pur operon were cloned and sequenced.
