PHB production by Bacillus megaterium strain MNSH1-9K-1 using low-cost media.

Plastics are widely used for diverse applications due to their versatility. However, their negative impact on ecosystems is undeniable due to their long-term degradation. Thus, there is a rising need for developing eco-friendlier alternatives to substitute fossil-based plastics, like biopolymers.

Characterization and cytotoxicity assessment of cadmium sulfide quantum dots synthesized with Fusarium oxysporum f. sp. lycopersici.

The potential of CdS quantum dots for biomedical and bioimaging applications depends on their cytotoxicity, which can be modulated by coating molecules. Using sulfur as a precursor can be used along with cadmium nitrate to synthesize CdS quantum dots with the fungus Fusarium oxysporum f. sp.

Biogenic Silver Nanoparticles and Stressors Generate Synergistic Growth Inhibition in Species through Cell Wall Damage, Osmotic Stress, and Oxidative Stress.

Nanotechnology, through the implementation of nanomaterials, has emerged as an infallible tool to treat various diseases caused by pathogens, where its mechanisms of action prevent the development of undesirable pharmacological resistance.

Objective: The antifungal activity and adjuvant properties of biogenic silver nanoparticles in different species (, and ) are evaluated.

Colorimetric Detection of Metals Using CdS-NPs Synthesized by an Organic Extract of Aspergillus niger.

The use of cadmium sulfide nanoparticles (CdS-NPs) synthesized by fungi presents highly stable chemical and optical characteristics; this makes them a promising alternative for development of colorimetric methods for metal detection. Moreover, application of CdS-NPs is challenging due to the biological material used to carry out synthesis and coating is highly diverse; therefore, it is necessary to evaluate if such components are present in the biological material. Thus, the objective of this work was to detect metallic ions in synthetic water samples using CdS-NPs synthesized by the extract of Aspergillus niger.

A new technique to evaluate Acidithiobacillus thiooxidans growth during a bioleaching process based on DNA quantification.

The potential of Acidithiobacillus (Thiobacillus) genus members, namely Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans, for bioleaching purposes is known. Specifically, previous studies have shown the potential of A. thiooxidans strain DSM 26636 used in bioleaching processes to remove metals in high-metal-content matrices.
