Representative Case Studies

Case 1: Enzyme Activity in Nitrogen–Sulfur Metabolism During Sewage Sludge Composting

This study investigated the effect of thermotolerant nitrifying microorganisms and sulfur-oxidizing bacteria on enzyme activity during sewage sludge composting. Six key enzymes related to nitrogen–sulfur metabolism were monitored. While microbial inoculation had minimal impact on overall community diversity, it altered community succession, reduced Actinobacteria abundance, and enriched genera closely linked to nitrogen and sulfur conversion. Importantly, inoculated compost (TR) showed enhanced activities of enzymes driving nitrification and sulfur oxidation, particularly in later composting stages. These findings demonstrate that targeted microbial inoculation stimulates nitrogen–sulfur transformation by boosting key enzyme activities, thereby improving composting efficiency and nutrient cycling.

Case 2: Enzyme Activity Response to High Pressure Processing in Apple Juice

This study evaluated how static and multi-pulsed high-pressure processing (HPP, 300–600 MPa, 5–15 min) influences enzyme activity in apple juice. Polyphenol oxidase (PPO) and peroxidase (POD) activities were significantly reduced by HPP, with maximum inactivation observed at 600 MPa—95% for PPO and 26% for POD. Interestingly, multi-pulsed HPP at 300 MPa × 3 pulses achieved greater enzyme inactivation than single-pulse treatments at higher pressures (450 MPa). These results highlight the sensitivity of oxidoreductive enzymes to pressure conditions, demonstrating that multi-pulsed HPP can be more effective for controlling enzymatic browning in apple juice while minimizing quality loss.
