Description

  • Application: Tuning Structural Characteristics of Corn Stover Through Ammonium and Sodium Sulfite (ASS) Pretreatment for Enhanced Enzymatic Hydrolysis.: This study demonstrates the effective use of sodium sulfite in pretreating biomass to enhance its enzymatic breakdown, crucial for improving biofuel production efficiency (Chen X et al., 2024). A Soy Protein-Based Film Based on Chemical Treatment and Microcrystalline Cellulose Reinforcement Obtained from Corn Husk Byproducts.: Highlights the application of sodium sulfite in the development of biodegradable films, showcasing its potential in creating sustainable materials in the food packaging industry (Zhang B et al., 2024). Sodium Sulfite as a Novel Hypoxia Revulsant Involved in Hypoxic Regulation in Escherichia coli.: Investigates sodium sulfite′s role as a hypoxia revulsant, providing insights into its biochemical applications for managing bacterial growth under low oxygen conditions, relevant for biomedical research and microbial management (Ye Q et al., 2024). Modelling energy-harvesting processes in primitive cells: Proton transport across bilayers driven by the oxidation of sulfite.: Explores the potential of sodium sulfite in facilitating proton transport across biological membranes, which is crucial for understanding cellular energy mechanisms and could lead to advancements in bioenergy and synthetic biology (Paula S et al., 2024).
  • Other Notes: Cleaves disulfide bonds to form the S-sulfonate derivative[1]; Inhibits gram positive bacteria in culture media;
