What is the production process of sodium hyaluronate raw material?

Production process of sodium hyaluronate API1、 Upstream fermentation (strain+seed cultivation+fermentation tank cultivation)a. Preservation and activation of bacterial strainsSelect engineered strains of Streptococcus suis that have been domesticated, have low endotoxins, and low hyaluronidase; Slope activation, step-by-step expansion cultivation (shaking bottle → primary seed tank → secondary seed tank), to ensure the purity of the bacterial species and prevent contamination by miscellaneous bacteria.b. Fermentation tank cultivation (core, determining molecular weight)Culture medium: glucose (carbon source), yeast powder, […]

Application Characteristics of Levothyroxine

1、 Characteristics of Pharmaceutical API Applicationsa. Efficacy matching natural musk: Levothyrone is the active chiral monomer in natural musk, which is the core raw material of artificial musk and meets pharmacopoeia standards. It can replace natural musk in compliance and protect wild musk resources.b. Fat soluble advantages of suitable formulations: high LogP, easy to penetrate biological membranes, suitable for making fat soluble traditional Chinese medicine formulations such as tinctures, ointments, drop pills, aerosols, etc; Poor […]
