The present invention includes a method of preserving cannabinoid concentration in a biomass comprising: providing a hemp biomass in an aqueous solution; adding a culture of a cannabinoid preservingbacteria to the hemp biomass solution; and culturing the hemp biomass with thebacteria under conditions in which the cannabinoid concentration is maintained.

Cannabinoid and terpene preservation in biomass using whole fermentation broth

Hydroxycarboxylic acids, e.g., 3-hydroxypropionic acid, and/or their ammonium salts are dehydrated to their corresponding unsaturated carboxylic acids, e.g., acrylic acid, by a process that uses a catalyst comprising ammonium bisulfate. The use of ammonium bisulfate reduces or eliminates the problems associated with processes that use sulfuric acid as a dehydrating catalyst, e.g, excess sulfuric acid consumption and/or recovery.

Ammonium bisulfate catalyzed dehydration of beta-hydroxy acids

Methods and systems for producing high purity 3-hydroxypropionic acid (3-HP) from an aqueous medium, such as a fermentation broth, are described. Aqueous 3-HP solution can be purified by flash evaporation wherein the 3-HP is vaporized at an elevated temperature without conversion to acrylic acid. This process can be integrated with downstream processes for producing other chemical and consumer products.
