Dissimilatory reduction of Fe(III) by a novel Serratia marcescens strain with special insight into the influence of prodigiosin.

A novel pigmented bacterium, initially identified as 11E, was isolated from a site historically known to have various iron-related ores. Phylogenetic analysis of this bacterial strain showed that it belongs to Serratia marcescens. This pigmented S.

Electrospun Membranes Based on Schizophyllan-PVOH and Hamamelis Virginiana Extract: Antimicrobial Activity Against Microorganisms of Medical Importance.

Electrospinning is a micrometric or nanometric scale fiber manufacturing technique with structural factors such as greater contact surface and pore size that allows the incorporation of biological agents in its structure, increasing their potential for medical applications. Due to the conditions required for the electrospinning process, such as high voltage, in the present work, the evaluation of the antimicrobial activity of schizophyllan-based membranes elaborated by electrospinning at 20 kV incorporated with Hamamelis virginiana was carried out against Staphylococcus aureus, Candida albicans and Pseudomonas aeruginosa. The schizophyllan production was 1.

Microbial Competition of Rhodotorula mucilaginosa UANL-001L and E. coli increase biosynthesis of Non-Toxic Exopolysaccharide with Applications as a Wide-Spectrum Antimicrobial.

Bacterial species are able to colonize and establish communities in biotic and abiotic surfaces. Moreover, within the past five decades, incidence of bacterial strains resistant to currently used antibiotics has increased dramatically. This has led to diverse health issues and economical losses for different industries.

Reduction of chromium (VI) from aqueous solution by biomass of Cladosporium cladosporioides.

The capacity of Cladosporium cladosporioides biomass for removal of Cr(VI) in aqueous solutions was evaluated. A 2 × 2 factorial experiment design was used to study the effects of pH and biomass doses. Lower pH values and larger biomass doses increased the capacity of C.

Metal-Induced Production of a Novel Bioadsorbent Exopolysaccharide in a Native Rhodotorula mucilaginosa from the Mexican Northeastern Region.

There is a current need to develop low-cost strategies to degrade and eliminate industrially used colorants discharged into the environment. Colorants discharged into natural water streams pose various threats, including: toxicity, degradation of aesthetics and inhibiting sunlight penetration into aquatic ecosystems. Dyes and colorants usually have complex aromatic molecular structures, which make them very stable and difficult to degrade and eliminate by conventional water treatment systems.
