METHODS OF OBTAINING LIPIDS FROM A MICROBIAL CELL COMPOSITION
The present invention is directed to a process for obtaining a lipid from a composition comprising microbial cells, the process comprising: treating the composition comprising microbial cells to a temperature of about 60° C. to about 95° C. at a pH of about 9 to about 11; separating the treated microbial cells into a light phase and a heavy phase; sequentially, in one or more cycles, raising the pH of the concentrated microbial cell composition to 10 or above, followed by lowering the pH of the concentrated microbial cell composition to a pH of less than 6 to lyse the concentrated microbial cell composition, wherein the raising and lowering of the pH also demulsifies the concentrated microbial cell composition; separating the lipid from the demulsified cell composition, and recovering the lipid.
Process for purification of malonic acid from fermentation broth
A process for the preparation of bio-based malonic acid and crystalline calcium malonate is provided. The calcium malonate is highly pure and provides a source of malonic acid made from a renewable carbon source rather than existing processes which rely on the use of petroleum-based products. The calcium malonate provides an improved source of malonic acid, which is important to many industrial processes.

PROCESS FOR SEPARATING A CONSTITUENT/CANNABINOID USING A CHROMATOGRAPHIC RESIN
A method for purification and separation of cannabinoids, such as cannabidiol and tetrahydrocannabinol, e.g., from dried hemp and cannabis leaves can use a continuous simulated moving bed process, a batch column chromatography method, or a single column, and a combination of one or more of a sequence of purification steps including: filtration, decolorization, activation or decarboxylation, dewaxing, polishing, and crystallization to separate a cannabinoid from the cannabis plant and to provide various cannabinoid products. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.

ELECTRIC HEATING OF BOILER FEEDWATER IN THE MANUFACTURE OF PURIFIED AROMATIC CARBOXYLIC ACIDS
Processes for manufacturing purified aromatic carboxylic carboxylic acids includes: generating high-pressure steam (402) from boiler feed water supplied to a boiler (404); heating a crude aromatic carboxylic acid using the high-pressure steam (402), whereby the high pressure steam (402) is condensed to form a high-pressure condensate (426); and purifying the crude aromatic carboxylic acid to form a purified aromatic carboxylic acid. The boiler feed water includes at least a portion of the high-pressure condensate (426) and makeup boiler feed water from at least one additional source. The recycled high-pressure condensate (426) is pre-heated with an electric heater (480) using electricity generated in an off-gas treatment zone (350).

METHOD FOR PRODUCING ACETIC ACID
Provided is an acetic acid production method including an absorption step that enables efficient and energy-saving separation of methyl iodide in a downstream step, when provided, of separating methyl iodide from a solution after the absorption of methyl iodide. The acetic acid production method according to the present invention includes an absorption step in an acetic acid production process. In the absorption step, at least a portion of offgases formed in the process is fed to an absorption column, is brought into contact with an absorbent including an organic acid having a higher boiling point as compared with acetic acid to allow the absorbent to absorb an iodine compound from the offgas, and a gas having a lower iodine compound concentration as compared with the offgas, and a solution containing the absorbent and the iodine compound are thereby to be separated.
