Article Synopsis
- * They altered different conditions such as carbon and nitrogen sources, salt levels, and pH, discovering that these changes significantly affected both biomass yield and the chemical diversity of the metabolites produced.
- * The findings revealed that while adjustments altered the metabolites involved, the resulting extracts showed strong antibacterial activity against common pathogens like Staphylococcus aureus and Escherichia coli, regardless of the specific conditions used.
Fungal laccases are promising for biotechnological applications, including bioremediation and dye biotransformation, due to their high redox potential and broad substrate specificity. However, current bioprospecting methods for identifying laccase-producing fungi can be challenging and time-consuming. For early detection, it was developed a three-step, multi-criteria weighting system that evaluates fungal strains based on: First, the biotransformation capacity of three dyes (i.

There is little evidence of research advances to generate alternatives for using these wastes.

Herein, the heterotrophic cultivation of was systematically studied, allowing us to detect a nutritional deficiency other than the carbon source through assessing the oxygen transfer rate for glucose or acetate fermentation. Consequently, a mathematical model of the iron co-limiting effect on heterotrophic microalgae was developed by exploring its ability to regulate the specific growth rate and yield.

- Endocrine disruptors (EDs) are environmental pollutants that interfere with hormonal functions and are found in items like synthetic fertilizers, electronic waste, and food additives.
- They can act as obesogenic compounds, affecting lipid metabolism and the formation of fat cells (adipogenesis).
- The review examines recent evidence on various EDs such as persistent organic pollutants, heavy metals, triclosan, and others, discussing their effects on adipocyte differentiation in various models.
