Olive mill wastewaters (OMWW) are characterized by a large concentration of pollutants, among which polyphenols represent a large part. This study investigated the effect of different dilutions of a culture medium enriched with olive-derived phenolic compounds on Chlorella vulgaris growth and its ability to degrade each one of them. In particular, polyphenols were precisely identified and quantified by HPLC-DAD analysis, showing high removal efficiency by C.

Article Synopsis
  • The study optimized the production of collagenase and protease enzymes from Aspergillus heteromorphus URM0269 using submerged fermentation with soybean flour as the primary substrate, achieving maximum enzyme production under specific concentrations of substrate and yeast extract.
  • After scaling up the fermentation process in a stirred tank bioreactor, collagenase activity significantly increased while protease activity decreased, highlighting a shift in enzyme production dynamics.
  • The research found that collagenase functions best at 40°C and pH 6.0, indicating its potential use in biotechnology, and also provided thermodynamic parameters that suggest the feasibility of using soybean flour as a sustainable resource for enzyme production.

Food packaging, which is typically made of paper/cardboard, glass, metal, and plastic, is essential for protecting and preserving food. However, the impact of conventional food packaging and especially the predominant use of plastics, due to their versatility and low cost, bring serious environmental and health problems such as pollution by micro and nanoplastics. In response to these challenges, biotechnology emerges as a new way for improving packaging by providing biopolymers as sustainable alternatives.

Cardiovascular diseases, resulting from the deposition of clots in blood vessels, are the leading cause of death worldwide. Fibrinolytic enzymatic activity can catalyze blood clot degradation. Findings show that 36 fungal isolates recovered from Caatinga soils have the potential to produce fibrinolytic protease under submerged conditions.
