Abstract: A process of making a fuel product as an additive from a non-auto-combustible high protein organic material for the destruction of polyfluoro compounds in a thermal process system is provided. Thermal reactions within thermal reaction equipment are controlled by controlling the moisture and oxygen in the reaction atmosphere of the equipment and energy inputs at or downstream of a thermal reaction chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy within the thermal reaction equipment environment are controlled to destroy hazardous polyfluoro compounds.

Abstract: The present disclosure is concerned with the production of high molecular weight hyaluronic acid suitable for medicinal administration to mammals without provoking an immune response from microbiological fermentation. The cultures may be prepared from specially developed strains of hyaluronic acid generating bacteria obtained by passaging in serologically negative host animal blood. The cultures are kept in log phase growth for an extended period by appropriate temperature, pH and glucose content adjustments. If the cultured strain is not hyaluronidase negative the hyaluronidase activity is inhibited. The hyaluronic acid is precipitated from the culture by the sequential addition of an anionic surfactant and then a cationic surfactant and extended from the precipitate with a high molarity aqueous calcium ion solution. The isolated aqueous hyaluronic acid solution may then be purified by passage through a nitrocellulose filter.
