  • Microbial process for the production of D(-)-N-carbamoylphenylglycine
    Patent number: 6280979
    Abstract: A microbial process for the preparation of D(-)-N-carbamoylphenylglycine from DL-5-phenylhydantoin which comprises culturing the strain pseudomonas sp. having Accession No. NCIM 5070 (ATCC 55940) and deposited in National Collection of Industrial Microorganisms (NCIM), National Chemical Laboratory (NCL) (India), having hydantoinase activity, in a medium for 16-20 hours, separating the cells by centrifugation, treating the solid cells obtained with DL-5-phenylhydantoin in buffer, at a temperature in the range of about 25-30° C. for a period of about 2-6 hours, acidifying the mixture to obtain solid D(-)-N-carbamoylphenylglycine, and separating the product by filtration.

  • Process for the recovery of tartaric acid and other products from tamarind pulp
    Patent number: 5994533
    Abstract: The invention provides Potassium bitartrate, pectin, L(+) tartaric acid and fruit sugars present in tamarind pulp, which are recovered sequentially by extracting the pulp in water, concentrating and chilling the extract, filtering out potassium bitartrate, precipitating out pectin from the filtrate by addition of acetone, extracting L(+) tartaric acid selectively by complexation with tertiary amine and recovering from the amine layer by back extraction into aqueous layer in the presence of a diluent at around 70.degree. C. followed by concentration and drying of the aqueous layer and treating the raffinate layer from solvent extraction with activated carbon, anion exchange resin, and concentrating to yield sugar containing 70% sugars.
